==============================================================================
Q. What was the Atari Jaguar/Jaguar64?
A. The Atari Jaguar was the world's first 64-bit home console video game
system. Developed after three years of research, manufactured by IBM, the
Jaguar was released in Fall 1993, and offered high-speed action,
CD-quality sound, and polygon graphics processing beyond most other
machines available at the time.
Orignally released as the Jaguar, Atari had, at times, referred to the
machine as the "Jaguar64" for marketing purposes. For the sake of
simplicity in this document, the term "Jaguar" will be used.
==============================================================================
Q. What was included when you bought a Jaguar?
A. The Jaguar was first sold for $250. It came with the Jaguar itself, one
controller, an AC adapter, a television RF switch box, and the CYBERMORPH
video game. Later on, the Jaguar was sold without a game, and as time
progressed, the Jaguar was sold for $150, then $99.
==============================================================================
Q. What happened to Atari, anyway?
A. The trials and tribulations of Atari could fill a small book (and, in
fact, once did). To summarize VERY briefly, the history of Atari is as
follows:
1972 Atari Inc. founded by Nolan Bushnell from a $250 investment.
Pong arcade game becomes a smash sensation.
1976 Atari Inc. sold by Bushnell to Warner Inc. for $28 million.
1980 Atari Inc. posts record sales. $2 billion profits annually.
Atari occupies 80 offices in Sunnyvale, CA.
1983 Decline of video games and irresponsible spending by Atari Inc.
results in record losses ($536 million, up to $2 million
daily).
1984 Warner divides Atari Inc. Home division (Atari Corp.) is sold to
Jack Tramiel.
1985 Atari Corp. releases Atari ST home computer.
1989 Atari Corp. releases Atari Lynx, the world's first color
hand-held video game system (see the Atari Lynx FAQ).
1993 Atari Games becomes Time-Warner Interactive.
1993 Atari Corp. releases Atari Jaguar, the world's first 64-bit home
video game system.
1996 Time-Warner Interactive (Atari Games) sold to WMS.
1996 Atari Corp. announces reverse merger with JTS Corporation.
1996 Atari Corp. and JTS connsumate deal on July 31 1996.
1998 Hasbro acquires the rights to Atari Corp.'s name and properties
1999 Hasbro releases their rights to the Jaguar to the public; Atari
is reborn as their new home video game label.
2000 Infogrammes Entertainment purchases Hasbro Interactive,
including all of Hasbro's rights to the Atari name and all of
its properties, for $95,000,000 in Infogrames stock and
$5,000,000 in cash.
2003 Infogrammes changes its name to Atari.
==============================================================================
Q. What was IBM's role in the Jaguar?
A. IBM had a $500 million contract with Atari Corp. to assemble, test,
package, and distribute Jaguar units. Manufacturing was done at IBM's
Charlotte, NC facility, and the Jaguar was IBM's first attempt at
producing a consumer-grade product for an outside vendor. By mid-1994,
Jaguar units were also manufactured by Comptronix in Colorado Springs.
Jaguar circuit boards were manufactured and assembled by an IBM
subcontractor; IBM then cased, tested, and packaged final Jaguar units,
which were then sent to Atari. IBM had no participation in the actual
design of the Jaguar chipset.
==============================================================================
Q. Okay, who did design the Jaguar?
A. The primary designers of the Jaguar were Martin Brennan and John
Mathieson. They started their own company in 1986 called Flare 1, and
designed an original multiprocessor game console. After the system was
finished, Flare wanted to "evolve" the system, but needed funding for the
job. Atari was contacted, believed in the idea, and agreed to
participate. Atari, Brennan, and Mathieson started a new company called
Flare 2 to develop the system. As Jaguar development moved along, it
became apparent that the machine would leapfrog the then-new systems from
Nintendo and Sega (the Super Nintendo and Sega Genesis, respectively), so
they decided to bring the machine to light. The entire process took three
years, from initial design to production-ready models.
The proprietary Jaguar chipsets were manufactured by Toshiba and Motorola.
According to Chris Gibbs, Attention To Detail was asked to write
technology demos for the Jaguar chipset. The company opted to develop a
game instead, resulting in the first Jaguar title, CYBERMORPH.
The Flare design was was reportedly based on a project called "Loki,"
developed by Sinclair Research. Information about the Loki project can
be found at http://www.nvg.ntnu.no/sinclair/planet/lokifram.htm
According to Jaguar developer Andrew Whittaker, "Some of that [Loki]
technology also found a home in a machine called the SAM Coupe, which was
manufactured and produced in the UK by MGT technologies (Bruce Gordon and
Alan Miles, both ex-Sinclair staff also). It shared many interesting
features with the Jaguar in terms of its video chip, but the machine sold
very badly in Europe and the company folded."
==============================================================================
Q. What are the specifications of the Jaguar?
A. Physical dimensions:
Size: 9.5" x 10" x 2.5"
Controls: Power on/off
Display: Programmable screen resolution. Horizontal resolution is
dependent on the amount of scanline buffer space given to the
"Tom" graphics processor. Maximum vertical resolution varies
according to the refresh rate (NTSC or PAL). Reportedly, a
stock Jaguar (without additional memory) running NTSC can
display up to 576 rows of pixels.
24-bit "True Color" display with 16,777,216 colors
simultaneously (additional 8 bits of supplimental graphics
data support possible)
Multiple-resolution, multiple-color depth objects (monochrome,
2-bit, 4-bit, 8-bit, 16-bit, 24-bit) can be used
simultaneously
Ports: Cartridge slot/expansion port (32 bits)
RF video output
Video edge connector (video/audio output)
(supports NTSC and PAL; provides S-Video, Composite, RGB
outputs, accessible by optional add-on connector)
Two controller ports
Digital Signal Processor port (includes high-speed synchronous
serial input/output)
Controllers: Eight-directional joypad
Size 6.25" x 5" x 1.6", cord 7 feet
Three fire buttons (A, B, C)
Pause and Option buttons
12-key keypad (accepts game-specific overlays)
The Jaguar has five processors which are contained in three chips. Two of
the chips are proprietary designs, nicknamed "Tom" and "Jerry". The third
chip is a standard Motorola 68000, and used as a coprocessor. Tom and
Jerry are built using an 0.5 micron silicon process. With proper
programming, all five processors can run in parallel.

Communication is performed with a high speed 64-bit data bus, rated at
106.364 megabytes/second. The 68000 is only able to access 16 bits of
this bus at a time.
The Jaguar contains two megabytes (16 megabits) of fast page-mode DRAM,
in four chips with 512 K each. Game cartridges can support up to six
megabytes (48 megabits) of information, and can contain an EEPROM
(electrically erasable/programmable read-only memory) chip to save game
information and settings. Up to 100,000 writes can be performed with the
EEPROM; after that, future writes may not be saved (performance varies
widely, but 100,000 is a guaranteed minimum). Depending on use, this
limit should take from 10 to 50 years to reach.
The Jaguar uses 24-bit addressing, and is reportedly capable of accessing
data as follows:
Six megabytes cartridge ROM
Eight megabytes DRAM
Two megabytes miscellaneous/expansion
All of the processors can access the main DRAM memory area directly. The
Digital Signal Processor and the Graphics Processor can execute code out
of either their internal caches, or out of main memory. The only
limitations are that
(1) "jump" instructions in main memory have certain restrictions; the JMP
(unconditional jump) command is longword-aligned, while the JR
(jump-indexed-by-register) command must be either word- or longword-
aligned. And
(2) running out of the cache is much faster (up to four times faster) and
efficient.
Some believe that the inability to jump/branch in main memory makes the
main memory feature useless.
Swapping data between the caches and the main memory is a quick, low
overhead operation, and therefore the main memory is often used as "swap
space" for cache code. The RISC compiler included in the latest Jaguar
developer's kit produced code that transparently swaps code through the
cache. This effectively allowed developers write RISC code without
concern for the cache size limits.
Compressed cartridge data can be uncompressed in real-time, and ratios of
up to 14:1 have been cited. In theory, a Jaguar cartridge can store up to
84 megabytes (672 megabits) of data, though actual results will vary
widely (most often, images are compressed, while sound and code are not).
Compression is performed with BPEG, an enhanced JPEG image decompression
mechanism. BPEG supercedes the former JagPEG algorithm, working up to 10
times faster and with more flexibility.
Other Jaguar features:
- Support for ComLynx I/O for communications with the Atari Lynx hand-held
game system and networked multiconsole games (on DSP port, accessible
by optional add-on connector). Networking of up to 32 Jaguar units
available.
- The two controller ports can be expanded to support "dozens" of
controllers
- Digital and analog interfaces
- Keyboards, mice, and light guns are possible
- Expansion port allows connection to cable TV and other networks
- Digital Signal Processor port allows connection to modems and digital
audio peripherals (such as DAT players)
- One megabyte per second serial interface
- 9600 baud, RS-232 serial port (accessible with optional interface)
- General-purpose I/O bits via the cartridge port
- Can accomodate future expansions of different processor types, I/O
types, video types, and memory types and/or quantities.
==============================================================================
Q. Was the Jaguar really a 64-bit system?
A. The question is hard to resolve, largely because the definition of what
constitutes an "N-bit" system has not been set. Of the five processors in
the Jaguar, only the object processor and the blitter are "true" 64-bit
components. Because the blitter and the object processor are in the Tom
chip, by extension Tom is a 64-bit chip. Furthermore, the Jaguar also
used a 64-bit memory architecture, according to Jez San of Argonaut
Software.
Some say the Jaguar should be considered a 32-bit system, as that is the
maximum register size in the programmable processors (the 68000, the
graphics processor, and the DMA sound processor). Others say the Jaguar
can be considered a 64-bit system, because 64-bit components are used, and
the GPU can access 64 bits of data if required. Again, the lack of an
agreed-upon definition serves to complicate the issue.
According to Jaguar designer John Mathieson, "Jaguar has a 64-bit memory
interface to get a high bandwidth out of cheap DRAM. ... Where the system
needs to be 64 bit then it is 64 bit, so the Object Processor, which takes
data from DRAM and builds the display is 64 bit; and the blitter, which
does all the 3D rendering, screen clearing, and pixel shuffling, is 64
bit. Where the system does not need to be 64 bit, it isn't. There is no
point in a 64 bit address space in a games console! 3D calculations and
audio processing do not generally use 64-bit numbers, so there would be no
advantage to 64 bit processors for this.
"Jaguar has the data shifting power of a 64 bit system, which is what
matters for games, so can reasonably be considered a 64 bit system. But
that doesn't mean it has to be 64 bits throughout."
For the record, the opinion of most third party developers and observers
is that the Jaguar is indeed a 64-bit system. The emphasis is on the word
"system"; while not every component is 64 bits, the Jaguar architecture,
as a COMPLETE SYSTEM, is.
==============================================================================
Q. The Jaguar used a 68000. Isn't that the CPU?
A. Again, quoting from Jaguar designer John Mathieson, "It may be the CPU in
the sense that it's the centre of operation, and boot-straps the machine,
and starts everything else going; however, it is not the centre of
Jaguar's power. ... The 68000 is like a manager who does no real work, but
tells everybody else what to do."
And...
"Atari were keen to use a 68K family device, and we looked closely at
various members. We did actually build a couple of 68030 versions of the
early beta developers systems, and for a while were going to use a 68020.
However, this turned out too expensive. We also considered the
possibility of no [Motorola 680x0 chip] at all. I always felt it was
important to have some normal processor, to give developers a warm feeling
when they start. The 68K is inexpensive and does that job well. I
maintain that it's only there to read the joysticks."
In rebuttal, Jaguar developer Andrew Whittaker notes, "In practice, what
many of us did with our titles was use the 68000 for AI and gameplay
logic, and have the custom chips drive the rendering to screen and 3D
code."
==============================================================================
Q. How could a graphics processor be the CPU?
A. The 64-bit custom graphics chip was a good general purpose RISC unit, but
it had been optimized for graphics work. Developers were free to specify
which processor(s) to use in a program, as desired.
==============================================================================
Q. What kind of special effects could the Jaguar do?
A. The Jaguar was capable of doing the following visual effects:
- High-speed scrolling (Object Processor).
- Texture mapping on two- and three-dimensional objects (GPU and Blitter).
- Morphing one object into another object (GPU).
- Scaling, rotation, distortion, and skewing of sprites and images
(Object Processor).
- Lighting and shading from single and multiple light sources (GPU and
Blitter).
- Transparency (Object Processor).
- "Rendering" up to 850 million one-bit pixels/second (35 million 24-bit
pixels/second, 26 million 32-bit pixels/second), or 50 million Goroud
shaded pixels/second. "Rendering" is believed to mean transferring a
pixel from a frame buffer to the screen.
- Sprites of "unlimited" size and quantity. Realistically, sprites can be
over 1,000 pixels wide/tall, and the number of sprites allowed is
limited by processor cycles instead of a fixed value in hardware
(Object processor).
- Programmable screen resolutions, from 160 to 800 pixels per line. The
resolution can be increased even further with additional hardware up
to a reported 1350 pixels per line.
One of the Jaguar modes is called "CRY mode", which supports lighting and
effects in 3D graphics. Red, green, and blue color elements are ranged
from 0 to 255, and the lighting level for any pixel can be changed by
setting one byte linearly. E.g., the relative proportions of red, blue,
and green are indicated with one byte, while a second byte selects an
overall intensity of 0 to 255. CRY allows much smoother shading of single
colors, but doesn't allow blending between colors as smoothly.
Actual graphics performance is hard to measure, as there are no industry-
standard benchmarks. Rebellion Software has claimed that the Jaguar can
render "10,000 Gourard shaded, large, 65536 color, any shape polygons per
second," while still performing other tasks. Presumably this level can
be increased further with optimized programming; indeed, some unofficial
calculations speculate that FIGHT FOR LIFE may generate between 20,000 to
40,000 texture-mapped polygons per second.
A key to understanding the Jaguar's performance is to realize that most
effects are accomplished by programming one of the processors to do the
job. To perform texture-mapping, for instance, required a developer to
write a texture-mapping routine for the GPU and/or blitter, then call it
as needed. The general-purpose nature of the Jaguar architecture gave
developers a lot of flexibility; unfortunately, the drawback was that
software routines for such effects are invariably slower and less
efficient than dedicated hardware chips and components.
==============================================================================
Q. How come the Jaguar claims to have "32-bit" graphics, when only 24 bits
are needed to render 16 million colors?
A. The additional 8-bits was for programmers to implement whatever visual
effects might be desired. Examples cited include Z-buffering (for polygon
graphics) and an alpha channel (for transparency).
==============================================================================
Q. Who were the third-party publishers/developers for the Jaguar?
A. The following companies have, at one time or another, been announced as
official developers, licensees, or publishers for the Jaguar. Note that
an official announcement was not an obligation for a company to produce
Jaguar-related products; many times, it merely meant that the company made
a commitment to "consider" producing product(s) for Atari.

Q. What were the unreleased Jaguar games?
A: The following games were announced at one time or another as being planned
for the Jaguar. With the dissolution of Atari, the chances are very slim
that any of these games will ever be produced or released. However, a few
enterprising companies and individuals have considered plans to either
finish their Jaguar titles for release, to sell finished-but-unreleased
games, or to produce new games on their own.

Q. Where can I get a review and/or comments about ?
A: Robert A. Jung ([email protected]) has reviews of some Jaguar games and
peripherals. They are available on the world-wide web at his web site,
at http://www.digiserve.com/eescape/atari/Atari.shtml
==============================================================================
Q. Where can I find secrets, tips, and hints for ?
A. A comprehensive list of Jaguar cheats and codes is available from "The
Mage," at http://users.aol.com/TheMage1/jaguar/jagcodes.txt or
http://members.aol.com/TheMage1/jaguar/jagcodes.txt
Clay Halliwell maintains the Atari Jaguar Cheats and Codes FAQ, which he
updates regularly. It can be found on the world-wide web at
http://www.atarihq.com/jaglynx/jag/jagcheat.txt
==============================================================================
Q. Is there a Jaguar emulator available?
A. The world's first Atari Jaguar emulator has been unleashed! "Project
Tempest" is written by Ville Linde, and is available for Microsoft Windows,
Apple Macintosh, and Linux systems. It's still an early version, but
already plays several games. Visit http://pt.emuunlim.com/ for details,
downloads, and a discussion forum.
==============================================================================
Q. Some of my Jaguar games don't have overlays for the keypads. Where can I
get them?
A. Not all Jaguar games used overlays for the keypad; some titles didn't use
the keypad at all, while others used the keypad, but the developers did
not feel that an overlay was needed. Making your own keypads is certainly
possible; simply use an existing keypad for a template, draw whatever
designs you like, then cut and to fit.
Tony Price has made a number of overlays for Jaguar games that didn't
include them, dust covers for the keypads, and overlays for third-party
titles. He can be reached by mail at [email protected], or on the
internet at http://home.earthlink.net/~mfmurdock/jaguar/jaguar.htm
==============================================================================

instructions can be printed with additional equipment. Details are
available from local FSN service providers.
==============================================================================
Q. What's the information on the CD-ROM drive?
A. A double-speed CD-ROM drive was available. The CD drive has an access
time of 210 milliseconds, and has a sustained data transfer rate of 352.8K
per second. The CD-ROM drive features a modified data bus interface for
access to the Tom and Jerry chips almost directly, allowing for a higher
throughput rate on sound and graphics. Storage on a disc is approximately
790 megabytes (6,320 megabits). The CD-ROM drive plugs into the Jaguar's
cartridge slot. A pass-through cartridge slot allows cartridges to be
used with the CD-ROM attached. Separate memory cartridges allow Jaguar CD
games to be saved for later play.
The Jaguar CD format is a non-standard format that is not compatable with
the ISO-9660 standard. It uses audio-format sectors for data, which
allows for 2352 bytes of useable space in each sector. Unfortunately,
this leaves no provision for error correction or file system management
(though errors are detected by the CD drive hardware). Each disc is
copy-protected with encrypted data that is specially formatted to look
like an error. Attempts to copy a Jaguar CD will fail because it cannot
read the encrypted data, which means the copy will not work.
The Jaguar CD allows delivery of full-screen, full-motion video. The
CinePak video decompression system has been licensed from SuperMac
Technologies. It is a 7K routine in the GPU and can be included in any
CD-ROM software that needs it, allowing full-screen video at 24 frames per
second. Movie quality pictures can then be overlaid on the screen with
computer generated graphics if the game demands it. Time-Warner has
licensed a library of film clips from its movies to Atari.
The Jaguar CD has "Virtual Light Machine" built in. This program plays
audio CDs and generate accompanying color and visual effects that react to
the music and sounds. The user can control and select effects with the
Jaguar controller. Regular audio CD playback features (volume control,
track programming, etc.) are also available.
The Jaguar CD can also display CD+Graphics discs. Supplimental cartridges
for Kodak PhotoCD and MPEG-1 (Motion Picture Experts Group) compression
were considered. The MPEG cartridge would reportedly include extra RAM
for buffering and support the whitebook video format.
The drive was being manufactured by Philips in the United States. Its
dimensions are 6.5" x 10.5" x 3.5", and it weighs 1 pound, 10 ounces. The
price was $150, and includes the TEMPEST 2000 soundtrack audio disc, a
sampler for the CD game MYST, and two CD-ROM games: VID GRID and BLUE
LIGHTNING.
Atari also developed and patented (#5,607,356) a technology for the Jaugar
CD called "GameFilm". Essentally, GameFilm allowed different video clips
to be mixed and matched in real-time, with seamless integration of video,
subtitles and soundtracks. The player would control the movie by making
choices throughout the game, with multiple choices available at each point.
The only known GameFilm title was "Caves of Fear", where the player was
cast as a CIA agent on a mission in Uraguay to stop the development of a
deadly new virus. Though the game was neveer finished, its themes and
situations (up to and including assassinations) would probably have earned
it a Mature rating.
Gavin Fance ([email protected]) has confirmed that Jaguar CD
games are not region-specific; he was able to buy a North American (NTSC)
version of MYST and play it on his European (PAL) Jaguar.
==============================================================================
Q. What's the information on the virtual reality headset?
A. Atari Corp. and the Virtuality Group had signed a contract whereupon
Virtuality would develop virtual reality hwardware and software for the
Jaguar. In return, Virtuality would get the rights to port Jaguar VR
games to their Virtuality arcade consoles.
Though announced, the Jaguar VR was never produced. Unofficial reports
conflict on whether the unit was cancelled, suspended, and/or reworked.
Reasons given for the inaction ranged from Atari's needs to reassess their
investments and focus on core business, to the high suggested retail price
of the Jaguar VR headset, to Virtuality's problems in trying to create
a mass-market headset that could track head movement fast enough to avoid
motion sickness after a few minutes of play.
As originally reported, the Jaguar VR package consisted of two components:
(1) A lightweight headset (weighs less than one pound). It can be
adjusted for fit and works with or without glasses. Game graphics are
provided by a single 7", TFT active-matrix color LCD screen, with a
resolution of 260 by 400 pixels and up to 65,000 colors. Dual temple
speakers provide sound, and a built-in microphone allows player
communication in future networked games. A custom optical system
projects a binocular image to both eyes; it is aligned at infinity, so
focus adjustment is not needed. Two degrees of freedom (left/right
and up/down) are available. Field of view is 52 degrees horizontal by
40 degrees vertical.
(2) A tabletop-mounted tracking station. The station senses the position
of the controller and the headset with "V-Trak" infra-red tracking.
The tracking speed is 250 Hz, with a lag time of 4 milliseconds, four
times faster than Virtuality's arcade hardware. The tracker has a
range of approximately 100 degrees; multiple trackers can be daisy-
chained together to provide a complete 360-degree tracking range, but
most Jaguar VR games will not require a full 360 degrees.
The Jaguar VR equipment was designed to be played while sitting down, so
as to avoid injuries. if a player moves out of the tracking station's
range, a safety cutoff would have been triggered to suspend the game.
Jaguar VR games would have been written for use with the regular
controller, as well as a two-button "virtual gun" hand-held joystick. The
licensing agreement between Atari and Virtuality permitted authorized
Jaguar third-party software developers to write their own VR titles.
One product did come out of the Atari/Virtuality agrement. MISSILE
COMMAND 3D for the Jaguar provided virtual-reality type play, without the
need for special equipment or controllers. The game was later transported
to Virtuality's arcade systems.
Two working Jaguar VR prototypes are known to exist; both are owned by
Jason Smith ([email protected]). The headsets (and other Atari
Jaguar prototypes) can be seen on his web site, at
http://home.attbi.com/~jasonmissysmith/
==============================================================================
Q. What's the "Panther"?
A. Quick history lesson: Sometime in the late 1980s, Atari Corp. was doing
research and development on "next generation" video game consoles. There
were two systems, a 32-bit machine called the Panther, and a 64-bit
machine called the Jaguar. It is reported that work on the Jaguar was
progressing better/faster than expected, so Atari abandoned the Panther to
focus their energies on the Jaguar instead. Supposedly, if both machines
were fully developed, the Jaguar would have followed the Panther only two
years later.
Reports of development work on the Panther have been whispered since 1988;
some people have erroneously mistaken those rumors to be about the Jaguar.
The Panther reportedly was considered a "32-bit" machine by Atari, though
for reasons unknown. It featured three chips, consisting of a Motorola
68000 running at 16Mhz, an object processor called the Panther, and an
Ensoniq sound processor called Otis, featuring 32 sound channels. The
Panther could supposedly display 8,192 colors from a palette of 262,144
colors, and could display 65,535 sprites of any size simultaneously.
According to Jeff Minter, the Panther's sprite hardware was very similar
to the object processor in the Jaguar, to the point where both had the
same limitations. Putting too many sprites on a single scan-line, for
instance, would require too much time to draw the line and caused a
"tearing" effect in the affected row.
Stefan Walgenbach is the proud owner of a working Panther prototype. He
has a web page at http://www.HomeComputer.de/ devoted to all sorts of
information on the Panther.
==============================================================================
Q. What's the "Jaguar II"?
A. There's been a little confusion with this topic, since at least two
separate machines have been called a "Jaguar II." The first was to have
been an integrated Jaguar/Jaguar CD-ROM unit. That project has since been
cancelled, making the point moot.
The other Jaguar II was Atari's next video-game console. Though a final
design was never reached, initial prototypes were assembled, yielding the
following information:
* Main chipset (codename "Midsummer") developed by Motorola.
* Fully backwards compatable with the existing Jaguar. Would have been
able to play all Jaguar games and use all Jaguar peripherals.
* Uses new "Oberon" and "Puck" chips. "Oberon" was the next generation of
the Jaguar's "Tom" chip, and "Puck" (also identified as "Thesus") was
a redesigned "Jerry".
* "Oberon" was so large that it required a dedicated cooling fan, powered
by a separate power supply. It's uncertain if this inefficiency was
simply due to the unfinished nature of the chip or not.
* Processing speed "two to four times faster than the Sony PlayStation."
* Full C/C++ development package available.
The following is one set of proposed specifications for the Jaguar II:
Size: 10.5" x 12" x 3.5"
Controls: Power on/off
Display: Resolution up to 1600 x 600 pixels (50 Hz/interlace)
32-bit "Extended True Color" display with 16,777,216
colors simultaneously (additional 8 bits of supplimental
graphics data support possible)
Multiple-resolution, multiple-color depth objects
(monochrome, 2-bit, 4-bit, 8-bit, 16-bit, 24-bit) can be
used simultaneously
Ports: Cartridge slot/expansion port (64 bits)
RF video output
Video edge connector (video/audio output)
(supports NTSC and PAL; provides S-Video, Composite, RGB
outputs, accessible by optional add-on connector)
Four controller ports
Digital Signal Processor port (includes high-speed
synchronous serial input/output)
Controllers: Eight-directional joypad
Size 5" x 4.5" x 1.5", cord 7 feet
Six fire buttons (A, B, C, D, E, F)
Pause and Option buttons
12-key keypad (accepts game-specific overlays)
The Jaguar 2 has seven processors, which are contained in three chips.
Two of the chips are proprietary designs, nicknamed "Tom" and "Jerry".
The third chip is a standard Motorola 68EC020 used as a coprocessor.
Tom and Jerry are built using an 0.3 micron silicon process. With
proper programming, all seven processors can run in parallel.

time. The Jaguar 2 contains eight megabytes (64 megabits) of fast
page-mode DRAM, in eight chips with 1024 K each.

Q. What's the information on the CoJag and CoJag games?
A. To briefly recap, after the Jaguar was released, Time-Warner Interactive
(now a subsidiary of WMS/Midway known as Atari Games) licensed the Jaguar
architecture for use in arcade games. These systems were called "CoJag"
games, and consisted of a Jaguar chipset with additional memory, extra
storage, and other architectural changes.
Two CoJag games have been released:
* Area 51: A light-gun shooting game for two players. The Jaguar's 68000
was replaced with a 68020 or SGI R3K, and ran at 25 MHz. It was also
equipped with a four megabytes of RAM and a one gigabyte hard drive.
* Maximum Force: Another light-gun shooting game. The 68000 was replaced
with an SGI R3K, and came with six megabytes of RAM and a two gigabyte
hard drive.
While it was rumored that the TWI games "Primal Rage" and "T-Mek" were
also CoJag games, this is false; developer Al Vernon has confirmed that
those titles did not use any aspect of the Jaguar design or chipset.
One gamer ([email protected]) reports that he playtested a CoJag
game, "Freeze," that was never released. Here's a slightly-edited version
of his report:
"I saw Freeze a couple weeks ago at a local arcade pinball/video
game expo. The game made it to field test but didn't do well, so
Atari Games axed it early this year.
"Freeze was a puzzle game, most closely related to Bust-A-Move or
Super Puzzle Fighter II Turbo. You controlled a character at the
bottom of a rectangular grid, five wide and eight deep. You had
the following controls: move left, move right, throw, and special.
You start with a fish in your hands; when you press 'throw,' you
threw it into the grid, where it goes up until it hits something.
Once your hands are empty, a fish launcher gives you another.
"The goal is to get groupings of three or more similarly-colored
fish to touch each other, at which point they disappear. Holes
are filled in by reverse gravity -- the fish fall up. The game is
over when your grid is full of fish or ice.
"Here's where it gets original: when you get a group of fish to
disappear, you "freeze" a couple of fish on your opponent's field,
starting at the top and working down. A frozen fish doesn't work
for groupings; fish are unfrozen by making a group nearby. Empty
slots get frozen too (the ice is empty).
"The 'special' button is for a special attack. When you start the
game, you pick a character, which also decides which special attack
you get. I didn't play that much of the game, so I don't know how
the special works or when you get it. You could play one or two
players simultaneously. One player meant playing against computer
opponents, along with a bizarre story -- I usually played the
monkey character, who was searching for an alarm clock so he
wouldn't oversleep, and he asked his opponents for a clock.
"The game was pretty fun, and the graphics were nice. It had a
look like Trog -- simple 3D, bright saturated colors. It's a shame
it didn't fare better in field test."
Pictures of the Freeze prototype cabinet and game screen can be found at
http://www.cyberroach.com/cyromag/two/woa.htm
Scott Walters ([email protected]) claims that the unreleased Atari
fighting game, "Vicious Circle", was also developed as a CoJag game.
Images and information on this title is available at
http://www.klov.com/V/Vicious_Circle.html
In a really interesting twist to the CoJag legacy, Scott also reveals that
unmodified Jaguars were used as the main controller for two "kiddie rides".
The Jaguar was used in three rides by Carousel International -- Speedster
II, Skycopter II, and SpaceGuy (never released). All of the rides were
programmed by Mario Perdue, who wrote Breakout 2000. The rides are no
longer manufactured, but can still be found near supermarkets, K-Marts,
and some Chuck E. Cheese pizza parlors to this day.
==============================================================================
Q. Was there a difference in Jaguar games/units sold in different countries?
Do I need to keep track of PAL and NTSC versions of a game?
A. There is no difference in the Jaguar game software. A properly-written
Jaguar game detects PAL or NTSC at startup and changes the playfield size
and game speeds accordingly. A properly-written Jaguar game will run at
the same speed on either machine. There are no regional or national
market lock-outs as there are for other game consoles.
The Jaguar consoles themselves were configured differently, according to
the country they were sold in. The primary differences were in the video
output format (NTSC or PAL) and the power adapters (110 volt or 220 volt).
Due to the Jaguar's use of an external adapter, a step-down transformer is
not needed. A local PSU can be used so long as it matches these
specifications:
1. 9 volt direct current (DC)
2. 1.2 amps
3. Center pin negative
To use an American (NTSC) Jaguar in the UK, the PSUs from old Sinclair
computers and Sega Game Gears can be used without problems.
To use an American (NTSC) Jaguar in Europe, you will need a new power
adapter and a SCART lead to supply the Jaguar's RGB signals to the TV.
Some European TV sets might have also required changing the Jaguar display
from a 60Hz frame rate to 50Hz.
The 50Hz/60Hz frame rate is set by soldering pads on the bottom of the
Jaguar PCB. On an NTSC Jaguar, they're located on the bottom of the PCB
near the controller ports. The set labelled "R140" determines between
50Hz and 60Hz.
Finding R140 depends on which motherboard is in your Jaguar. As "Stone"
([email protected]) writes, "The location of R140 and whether it
is labelled or not depends on the revision of the Jaguar chipset. I
have two Jaguars, both PAL, one K-series and one M-series. The K series
has no silk-screen printing on the underside of the circuit board (and
thus the links are not labelled). The M-series has them labelled so
it's easy to figure out which resistor to remove.
"My BJL FAQ contains a section on building a 50/60Hz switch; the URL is
http://addie.voicegateway.com/bjl.asp -- please note that this mod is
dependent on your TV being able to accept the signal; you may find it
'letterboxes' it so you can see the whole screen, which isn't what you
want. :)"
If you have a K-series motherboard (which does not label the links), Russ
Juckes ([email protected]) gives instructions for finding them:
"Hold the Jaguar PCB with the Joystick ports to the bottom. On the
underside of the board, near the joystick ports, and to the left of centre
there are four links, the top and the bottom one bridged. (Both with zero
ohm resistors). Above them there is another link, with a brown resistor.
"The bottom link is the one that needs to be broken. I used a penknife to
scratch away the solder, and then a needle-nosed pair of pliers to break
the resistor.
"The links are *not* labelled in any way. As another guide to make sure
you are about to snip the correct link, they are placed directly
underneath a chip (which is obviously on the top of the PCB!) so if you
use a soldering iron, be careful!"
Once you have located R140, connect the two points for 50Hz, or leave them
disconnected for 60Hz, as follows:
60Hz 50Hz
o-o R135 o-o
o o R136 o o (Information courtesy of Martin Zimmer,
o o R137 o o [email protected])
o o R140 o-o
PAL Jaguars sold in Europe have the R140 pads connected with a zero ohm
SMD resistor, which can be removed with a soldering iron. It is possible
to wire a switch to the points, allowing the Jaguar to be toggled between
50Hz/60Hz. This is mainly useful for PAL Jaguars to play games at the
original speed and screen resolution of the NTSC version.
==============================================================================
Q. Hey! My Jaguar makes a quiet hissing sound! What's going on? Is it
dangerous?
A. Early Atari Jaguars had a rumored problem with the console hissing softly.
Atari had cited several reasons for the hissing noise. Some have said
that the sound is from the RF generator. The RF shield has holes in it
(ostensibly to help air flow and keep the unit cool), and it is believed
that the holes produce the noise.
Others said the sounds are produced by coil L29 which is responsible for
the proper voltage regulation to +10.0V, together with U38. The coil's
copper wire vibrates when the current through it changes abruptly, making
the hiss.
There are two solutions: 1) Use plastic spray or silicone rubber glue to
fix the coil's wire. 2) Replace the original Jaguar power-supply with a
variable power-source, using 7.5V DC instead of 9V DC (it is not certain
whether the Jaguar CD will require 9V DC, which would make this "fix"
unworkable with the CD drive).
In any case, the "hissing" noise was not dangerous, but merely annoying.
It was usually audible only if you put your ear next to the unit and
listen closely, and is not interference in the audio output. It is
roughly analogous to the buzz made by electric clocks.
Most later Jaguars did not have this problem, though a few rare cases have
been noted.
==============================================================================
Q. My Jaguar comes up with a red screen instead of a game! Is it broken?
A. Most often, the "red screen" problem appears after the Jaguar logo has
disappeared off the TV screen, and is caused by one of the following:
1. Poor contact between the Jaguar and the cartridge (most likely). Make
sure that the cartridge is firmly seated in the cartridge slot, and that
contacts are not dirty/dusty.
2. Bent pins in the cartridge slot (rare). This may be caused by rough
edges on some cartridges. The pins should be carefully straightened.
3. Defective cartridge (rare). If the red screen only appears with one
cartridge but not others, the game may be defective. Exchange it for
another.
If the Jaguar logo appears without problems, then the Jaguar is probably
working fine, and it's only the data transfer between the unit and the
cartridge that's causing the problem.
==============================================================================
Q. I've heard stories about the Jaguar version of DOOM having network errors
when playing with two Jaguars linked together. Are they real? If so,
what causes the problem, and can I avoid it?
A. There is some truth to the reports -- when linking two Jaguars together
for multiplayer DOOM games, network errors sometimes appear which
interfere with the gameplay. At worst, the game resets to the start of
the current level, which can be annoying if you're in the middle of a
heated Deathmatch firefight.
The problem stems from several causes. The networking code in DOOM was
not thoroughly tested before release, because the game was finished before
Atari settled on the final specifications for the JagLink cable (the cable
came out almost a year after DOOM did). As a result, this causes some
problems due to integration differences. On the other hand, some of the
folks playing networked DOOM are using their own home-made link cables,
which might not have enough shielding, which also causes errors. There
are reports that earlier Jaguar models are more susceptible to errors as
well, but the evidence is inconclusive.
Recommendations? Set up your Jaguars in an area relatively clean of
electromagnetic interference, make sure you are using a well-shielded
cable, and cross your fingers. And remember that, even with an
occassional networking error, DOOM is still lots of fun with a friend
(or foe).

Q. What's this about a rotary controller? What games use it? How do I make
one for myself?
A. TEMPEST 2000 has hidden in it an option for a rotary controller (at the
"Game Options" menu, press Pause on both controllers to activate the
"Controller Type"). No plans for an official Atari rotary controller were
announced, but many TEMPEST fans have been trying to build such a
controller, to give the game a feel that's close to its arcade original.
Andy Light has written instructions for taking a Jaguar joypad and an
Atari 2600 Driving Controller and building a rotary controller with the
parts. His instructions are condensed below. READ THE INSTRUCTIONS
THOROUGHLY BEFORE ASSEMBLY -- there are some areas that are left to the
whim of the builder, and advance planning is highly recommended.
* * *
ANDY LIGHT'S JAGUAR ROTARY CONTROLLER INSTRUCTIONS
Parts needed: Atari Jaguar controller
Atari 2600 Driving Controller (NOT the paddles)
13 wires, preferably of separate colors
Buttons
A board or box or shell to mount everything on/in
1. Open the driving controller by removing the two underside screws.
Inside is a top-like device or a grey box with three wires coming out of
it. This is the encoder. Pull the driving controller's knob off the
encoder's shaft, then remove the encoder by unscrewing the nut that holds
it in place. Disconnect the wires from the encoder.
2. Open the Jaguar controller. There are four screws on the bottom
holding it together, behind the round rubber pads. Inside the controller
are two circuit boards connected by a ribbon of wires. The bottom board
is for the numeric keypad and is held by two screws. Remove the screws
and take out the keypad.
3. Disconnect the wire ribbon from the keypad by melting the solder.
CAREFUL! This is delicate work -- get help if you need it. Solder the
thirteen wires where the ribbon connection was; do not confuse them.
4. From the left side of the board (the side that says "P2"), I've
numbered the wires as follows:
1) Common 5) Button A 9) Button C 13) Down
2) Right 6) Button B 10) Pause
3) Option 7) Button B 11) Up
4) Option 8) Button C 12) Left
5. On the encoder, connect wire #1 to the center terminal, #2 to the right
terminal, and #12 to the left terminal. The rotary part of the controller
is now finished.
6. How to connect the other controls is up to you. I'm using arcade
buttons, a thumbpad, and a switch (to toggle joypad or rotary control)
mounted in an Atari 5200 trak-ball controller case. You can mount a
joystick, extra buttons, or other features for your own controller.
Buttons and empty control boxes are available at stores such as Radio
Shack.
Wiring for the other signals are as follows:
Up - wires #1 and #11 Button A - wires #1 and #5
Down - wires #1 and #13 Button B - wires #6 and #7
Pause - wires #1 and #10 Button C - wires #8 and #9
Option - wires #3 and #4
Because wire #1 has multiple uses, you will either need to string it or
split it for each destination.
7. Reassemble and mount everything according to your design. For better
spin, you can glue lead fishing sinkers to the inside of the knob, and
lubricate the shaft of the encoder with light oil or silicone lubricant.
That's it! Please forgive me for any mistakes in my grammer, terminology,
spelling, etc. If you encounter any problems, feel free to e-mail me at
[email protected]. Good luck!

Q. I want something better than RF output from my Jaguar. What do I do?
A. Atari had an S-Video cable and a Composite video cable available for use
with the Jaguar. See the "Peripherals" section for details.

Q. How did the ComLynx port on the Jaguar work? Could I connect my Lynx to
it?
A. The Jaguar does not have a ComLynx port per se, but has a ComLynx signal
on the system bus. An expansion port add-on would have made the port
available, and developers had announced plans for such accessories. It is
possible to daisy-chain multiple Jaguars for multiplayer games into a
"Jaguar network". In theory, it would have also been possible to connect
Jaguars and Lynxes, though no plans for cross-system software were ever
finalized.
There was also talk that the Jaguar's ComLynx signal could allow Lynxes to
be used as peripherals: software could have been developed to allow Lynxes
to be part of a Jaguar game as "smart" controllers. Again, no actual
plans were ever announced.
For enterprising engineers who wish to build a ComLynx cable for two
Jaguars, the following schematics from [email protected] are available.

Assembly Notes:
As shown, the only 3 wires needed for the cable are 2, 3 and 6 (Tx, Rx,
and Ground). All of these wires are on the bottom connector, so that
is a good indicater of which way the cable plugs in the Jaguar.
Shielded and RF-Choked cables work best. Due to the nature of this
connector, it will be hard to shield this cable completely.
If you cannot find a 12-contact IDE Card Edge Connector, a 10-contact
version can be used. A quick one can be built with no soldering using
JDR MicroDevices (Part# IDE10). This is made for ribbon cable, but you
can use regular shielded cables with a little work. As long as lines 2,
3, and 6 remain properly connected, there should be no difference.
Usage tips:
* DO NOT PLUG THIS CABLE IN UPSIDE-DOWN! You may damage internal
components if you plug it incorrectly.
* TURN OFF BOTH JAGUARS BEFORE CONNECTING. You may damage internal
components if you do not.
* Since there isn't much strengh in the wires, remove the cable by the
connectors.

Q. Agh! My Jaguar is broken! How can I fix it?
A. Unforutnately, with the dissolution of Atari Corp., repair or replacement
of broken Jaguars is no longer available; Atari/JTS does not have any
units remaining for sale or replacement. On the other hand, with the low
price of clearance Jaguars today, it isn't expensive to buy a new unit.

Q. How was development for the Jaguar done?
A. Jaguar game development environments existed for the Atari TT030 computer
or an IBM PC/compatible. Art development could be performed on any
machine, whether a low-end Apple Macintosh or commercial rendering
software such as SoftImage. Wavefront's "GameWare" was the official 2D/3D
graphics development system; Atari itself used GameWare for in-company
development, and registered third-party Jaguar developers could buy
GameWare licenses at special discount prices.
Estimated price for a developer's package was $9,000 for the TT030 setup,
and $7,500 for the PC/compatible platform. The package included a Jaguar
development unit, documentation, and development/debugging software.
The Jaguar had modified boot firmware to run the development board (the
"Alpine board"), and it had a cable coming out to provide signals to the
Alpine board that are not normally present via the cartridge connector.
CD-ROM developement packages (including the cartridge development kit)
were ranged at about $8,000, and were upgradeable from the card-only kit.
Software routines packaged with the system included a multi-channel
polyphonic FM/Wavetable synth; JPEG decompression; video set-up; drawing
primitives; 3D rendering with gourad shading, texture mapping, and camera
manipulation. GCC is the primary 68000 C compiler; support for other
languages was not available from Atari, but developers were free to use
whatever tools they may prefer. The development toolkit ran under DOS,
TOS, or Linux. Work was proceeding on a Linux development system using
the GNU tools.
The centerpiece of the TT030 deveopment platform was DB, an assembly-
language level debugging tool. The Jaguar and the TT030 were connected
with a parallel cable, and software could be debugged interactively
without interfering with the Jaguar's screen display. DB supported the
use of scripts and aliases, which simplified the use of complex or common
functions.
Support for the development packages was primarily provided by Brainstorm
(Atari France), who worked closely with Atari Corp.
Atari granted final code approval, but did not see the need to "censor"
games. Every game was given one man-month of compatibility and quality
testing before it was approved. Atari offered technical support via FAX,
mail, electronic mail and voice. Atari allowed developers to source their
own cartridges, documentation and shells if desired. Jaguar software is
encrypted with a proprietary key, thus preventing unauthorized developers
from releasing Jaguar software.
Cross Products (SNASM) offered an alternative Jaguar Development system.
It came with a multiwindowed debugger, assemblers, compilers, and SCSI
support, for approximately $3,700. The package allowed for full screen,
source level debugging of multiple processors, in C or assembler. This
was software only for the IBM PC; the Jaguar development hardware (Alpine
board, modified Jaguar, etc.) had to be purchased separately from Atari.
Ambitious hobbyists have started their own unendorsed Jaguar development
efforts, with several "home-brewed" development systems and electronic
documentation of the Jaguar's inner workings. Several games have been
written for play on the "Jaguar Server" development system (requires some
hardware modification to an existing Jaguar, and an IBM PC or Atari ST
computer).

Q. Where is the encryption key for Jaguar games? Now that Hasbro has
declared the Jaguar an "open system", the key should be available to the
public, right?
A. Finally, yes -- in the beginning of 2001, the Classic Gaimg Expo announced
that they had finally recovered the software encryption codes for the
Jaguar and the Lynx. The codes (and supporting software tools) have been
released into the public domain. The codes are available on the web at
http://www.cgexpo.com/encrypt.html
==============================================================================
Q. Is there a way for people to write their own Jaguar games without the
encryption codes?
A: Certainly! Hobbists and developers have been writing their own Jaguar
games for a while now; the lack of an encryption key simply means they
can't distribute the game to non-developers.
To work around this need, JUGS -- the Jaguar Unmodified Game Server -- was
developed. JUGS is a computer hardware/software package that allows you to
download Jaguar games from your personal computer to a Jaguar and then run
them. With dozens of homebrewed Jaguar programs in existence, this opens
up a new source of software for the Jaguar enthusiast.
To use JUGS, you need the following:
* A copy of the game BattleSphere.
* An IBM-compatible PC with a RS-232 communications port.
* A JagLink interface.
