My Atari 8-bit stuff

Recommended Posts

I am going to sell off most of my Atari 8-bit hardware and software.  Rather than use one of those auction sites (that shall remain nameless), I am going to set it up on a website...

 

here...  https://cabellclarke.wixsite.com/website

So far, there are only a few pictures on the site but I will be adding individual items in the coming days...

If you see something you are interested in, drop me a line.

 

I don't intend to ship internationally so sorry to half the people on AA but I am in the US and shipping is a b|+ch these days and some of this stuff is huge (liked a boxed 1200XL or an Astra Big D.)

 

And so it begins...

That is a nice stack of 1050s! Wrong side of the pond for me though.

I actually have more 1050s than that... those are just the tested ones :)

Apparently you have as many 1050's as @bob1200xl has 1200XLs :)

 

Quite a collection you amassed of Atari gear. I too remember a time in the mid to late 90's where I could easily find boxes of stuff at flea markets for pennies on the dollar. One time I picked up a box of 50 8-bit carts for something like $5. So by the year 2001 I had quite a collection of my own. However... and I think I told this story, I had a single Mom and her two kids move in with me, and I needed room. So into the car everything went and I drove down to a swap meet in Santa Clara where I met Curt Vendel for the first time and without much difficulty convinced him to take it all off my hands for FREE. Little did I know in the near future which is now, it would all command crazy prices on eBay ;)

 

Since that time I have recollected at least 7 800XLs and various other Atari gear (it's a sickness).

It definitely is... :)

 

My problem is that I don't have enough room to display it while testing it.  I still have 2 boxes full of CPUs that aren't even in those pictures.

Speaking of XEP 80s...

 

How does one go about testing an XEP 80?  I've never messed with one. DO I need two monitors?

Got this off atarimania.com:

The Atari XEP80 interface connects to joystick port 1 or 2 on the Atari
computer and provides the system with:

- An 80-column Video Display Controller with phono output jack, carrying a
  monochrome composite video signal which can be either 60Hz (NTSC compatible)
  or 50Hz (PAL/SECAM compatible), selectable in software.
- A Parallel Printer Port (Centronics output interface)

Note that the XEP80 does not include provision for audio.

VIDEO DISPLAY CONTROLLER
The XEP80 video hardware generates an 80 column by 25 line text display
through a video connector/cable plugged into a separately purchased monitor.
The monitor can be any Composite Video input type, although for the best
display a monochrome is strongly advised.

Internally, the XEP80 is a 256 character wide by 25 line high storage device
with an 80 column wide display window.  Characters may be placed anywhere
within the device independent of the window location.  The window may be
scrolled across the 256 column wide field.

Optionally, the XEP80 may be placed into Pixel Graphics mode.  This mode
supports a bit mapped (pixel) screen of 320 dots (40 bytes) horizontal by 200
dots (lines) vertical.  The output window displayed is approximately half the
size of the text window.

The XEP80's composite video signal contains more horizontal scan lines per
field than are used in NTSC or PAL/SECAM color broadcast, composite video, or
Y/C video (S-video) signals.  The XEP80 outputs 250 scan lines of video per
field for the 60Hz signal compared to the NTSC standard of 243, or 300 scan
lines of video for the 50Hz signal compared to the PAL standard of 288.  Thus
the XEP80's output was ideal for high-resolution CRT-based monochrome
composite video monitors of the time, but settings on color televisions and
monitors must typically be adjusted, if possible, in order for the entire
video output signal to be viewable on the screen.

PARALLEL PORT
The XEP80 supports a functional subset of the Centronics or PC parallel
printer interface (standards introduced elsewhere in this FAQ list), using the
IBM PC standard (1981) connector.  Note that the Atari Operating System
resident P: device handler does not support a printer attached via joystick
port, so a substitute P: handler must be installed in RAM in order for Atari
software to recognize the XEP80 parallel port for printing.

        10. Not Used            18-25. Ground

SOFTWARE
The XEP80 Handler and Relocator is provided on diskette in the form of a DOS
binary file named AUTORUN.SYS.  This file is automatically loaded into memory
and initialized by the DOS at boot (power on) time.
Contents of the XEP80 Boot Disk: (DX5087)
  DOS.SYS       DOS 2.5 File Management Subsystem (FMS)
  DUP.SYS       DOS 2.5 Disk Utility Package (DUP)
  AUTORUN.SYS   XEP80 Handler and Relocator.
                Substitute versions for three OS-resident device handlers:
                 - S: Display Handler
                 - E: Screen Editor
                   Designed to be compatible with the standard E: device but
                   for the XEP80 80-column screen display.
                 - P: Printer.
                   Default configuration supports 8 different printer devices:
                      P1: XEP80 parallel port
                      P2: 850 Interface Module parallel port (e.g., Atari 825)
                      P3: 1025 Printer
                      P4: 1020 Color Plotter
                      P5: 1027 Printer
                      P6: 1029 Printer
                      P7: XMM801 Printer
                      P8: XDM121 Printer
                   The handler interprets P: (no device number) to mean, P1:
  RELOC.SRC     Relocater in assembly source
  XEP80HAN.SRC  Handler in assembly source
  DEMO80.BAS    Demonstrates overall XEP80 features
  MAKER.BAS     Program to generate an AUTORUN.SYS from a custom-made Handler
  ATRIBUTE.BAS  Demonstrates special text features
  WINDOW.BAS    Demonstrates the 256-character wide window
  EIGHTY.BAS    Displays a spreadsheet-like grid using the full XEP80 display
  GRAPHICS.BAS  Demonstrates graphics capability by drawing a sphere on screen
  PRINTER.BAS   Program to revise the default printer port configuration
  XEP80.DOC     Product Specification For XEP80 hardware and software

Hold down [Shift] while loading the XEP80 Handler and Relocator (AUTORUN.SYS)
to load the P: handler but not the S: and E: handlers (use the XEP80 for its
parallel printer port only).

The key engineer/designer of the XEP80 was Jose Valdes at Atari.
Lane Winner was software developer for the XEP80 at Atari.
The XEP80 was made in Taiwan.

The XEP80 draws 400mA of current from an external power supply.  Use a power
supply that delivers 500mA 9V DC (center positive).  Shipped with Atari
C016353 or C018084

BTW, you can make money via postage costs; buyers from around the planet will pay 4 or 5 times the postage costs to procure their item.

I think I am hallucinating (again)...

 

Does anyone else see the XEP80 docs displaying behind later messages?

I see it too.  I assume that this was no accident.  But how was it done? And why?

I've seen this many times.  However, it usually fixes with a refresh on the screen.  Not this time though.

How I created this mess:

Went to:

atarimania.com

 

Clicked on 'Official FAQ' tab.

Clicked on 6.1.2) and copy and pasted text into my AtariAge response.

 

Note AtariMania website has no https validation and OLD ABBUC website had recently been hacked.

 

Hope this helps webmaster,

 

Cheers, Chris

I would say to Albert... just delete the offending message.  I was able to capture the contents of what Chris posted before all the subsequent messages obscured it.

So it looks like some extra <div's> and other html elements got pasted in and actually were processed.  If all that gets removed everything displays fine.

It would probably be a good idea to strip out html in posts.  I get there's some formatting, but there's also some really nasty stuff that can happen.

The forum does not allow HTML in posts, so this is probably just a bug in the forum software in terms of the bad rendering.
