  1. Hi everyone. I'm putting together vintage computer and console related items which I hope to sell. Please click below to see the current items I'm listing. Items For Sale I'll be adding more as I test, and package the items. Thanks, John
  2. For Sale is a (late) 2009 mac mini its gotta 2.53 GHz Intel "Core 2 Duo" (P8700) GeForce 9400M "graphics" with a massive 256 megs of ram 8GB ddr 3 1333 Ram (maxed) 128GB Solid State Drive 100Meg network port 802.11 B/G/N wifi power adapter DVD drive seems to be dead, not bothered with replacing it, comes with OSX 10.11 el-captain VGA dongle (does not naturally support 1080p) DVI dongle OEM power supply Scratches Just on a whim I bought this machine from ebay as not working for parts. I cleaned it out with air and a brush, and replaced thermal paste ... added upgrades and its been fine. Its not a quick machine, being an earlier core 2 mobile chip, you can feel it in day to day operation. In my opinion its a toy, but maybe that is what you want If you want a daily driver, check out member classicrock909's post about 2012 dual core i5 mac mini's for 100 bucks (+ postage) slap an ssd and 8-16 gb ram in one of those and for less than 200 bucks you got a snappy arse machine for home/office/education use (I have been doing simple 3d cad, ie electronic enclosures for 3d printers, on mine in a 33 degree C (92f) garage) asking 65 shipped, USA and paypal only Thanks
  3. MAME 0.212 It’s the moment you’ve surely been waiting for: the release of MAME 0.212! A huge amount of work has gone into this release in a number of different areas. Starting with the software lists, you’ll find hundreds more clean cracks for Apple II, the Rainbow on Disk collection for Tandy Color Computer, all the latest Game Boy Advance dumps, and thousands more ZX Spectrum cassette images. Chess computers now support chess piece simulation using the built-in artwork, support has been added for several more chess computers from Hegener & Glaser, Novag and Saitek, and the Tasc ChessSystem R30 is now working. Three Game & Watch titles, Bomb Sweeper, Gold Cliff and Safe Buster, have been added for this release. Protection microcontrollers continue to fall, with Rainbow Islands – Extra Version, Choplifter, Wyvern F-0, 1943: The Battle of Midway and Bionic Commando no longer needing simulation, hacks or patches. In some cases, the dumps have confirmed that the protection had been reverse-engineered correctly and the simulation was correct, but it's still important to preserve these programs. It’s also important for people repairing these systems if the original microcontrollers have failed. There are three important sound-related fixes in this release: FM Towns CD audio playback positions have been fixed, Konami System 573 digital audio synchronisation has been improved, and a special low latency mode has been added for the PortAudio sound module. For more advanced users and developers, more functionality has been exposed to Lua scripts and plugins. The layout file format has been overhauled to better support systems that make creative use of LEDs and LCDs. Disassembler support has been added for the Fujitsu F2MC-16 and National Semiconductor CompactRISC CR16B architectures. And if you've been following along, you might notice that we’ve waved goodbye to a little more of our C legacy with the removal of the [tt]MACHINE_CONFIG_START[/tt] macro and its associated crud. We don't have space to list all the Apple II and ZX Spectrum software list additions here, but they’re in the whatsnew.txt file. You get the source and Windows binary packages from the download page.
  4. This is how the data is stored in files on this type of computer. NOTE: This is a work in progress. I will be updating this post as I think of stuff to put on here. Bytes $20-$7F represent the standard ASCII character set. Character $7F represents the cursor symbol. Bytes $00-$1F are control codes. $00 - ROM Section Header $01 - Palette $02 - Graphics $03 - Mappings $04 - $05 - $06 - $07 - $08 - Set Tab Width $09 - Tab $0A - Line Feed $0B - Comment Tab $0C - $0D - Carriage Return (same as $0A) $0E - $0F - $10 - $11 - $12 - $13 - $14 - $15 - $16 - $17 - $18 - $19 - $1A - $1B - $1C - $1D - Change Label Line Color $1E - Change Label Line Toggle $1F - Toggle Show/Hide Labels Characters $80-$FF are more control codes. When the file is saved, it is compressed using LZSS.
  5. A good assembler has ROM section headings. These are a way to cleanly divide the source code into settings, so you can definitely figure out at which address each section starts. Think of an assembler as if were like Microsoft Word. Section headings could appear as solid-colored bars with text on them. The user should have control over what color to make the bar. They also might have control over the font. For example, your main program header might look like this (note that all images are simulated): Notice I used the Roco font. Anyone familiar with Sonic The Hedgehog 2 will recognize this, but it's the actual font, not the Sonic 2-rendered one. Every computer program needs a vertical blank (or "V-Blank") routine. Its header might look like: One common thing to have in any program are math routines. So, you might include a section like this: For a hardware/software implementation, fonts could use a bitmap. Up to 96 different character glyphs can be stored. In addition, the numbers could be made a little bit bigger if the user chose to. Each character's bitmap can be stored using 1, 2, or 4 bits per pixel. For each character, the size needs to be specified, as well as where its glyph data can be found. For file storage, section headers could use this format (each pair of letters represents a byte): hh ff rr gg bb ll tt tt ... hh = Token for a section header (a fixed value). ff = Flags. If bit 7 is set, restart the numbering at 1. If bit 6 set, toggle whether the number is shown for this and later sections. rr gg bb = Section header color, a 24-bit RGB value. ll = Length of text. tt = The text shown. It doesn't include "Section #". It's in ASCII. Let's say that the section header token is $00, and I'll use the vertical blank section header as an example. The byte stream in the source file would look like this: 00 C0 00 60 20 0F 56 42 4C 41 4E 4B 20 52 4F 55 54 49 4E 45 53 The 00 signals the start of the section header. C0 means to make this section #1, and turn on section numbering (by default, it's off). 00 60 20 is the RGB value. It produces a dark green color. The 0F determines how many characters there will be in the section's name. The rest is the text, in ASCII. The text says "VBLANK ROUTINES". Section headers are not taken into account when compiling a ROM. They are there to cleanly divide source code. When the file is opened, the number of headers is counted, and section numbers are assigned accordingly.

    Section Header 0

    From the album: The Best Assembly Computer

    This is what the section header for the main program would look like. Note that it doesn't have a section number.
  8. From the album: My Game Collection

    A floppy Drive controller for a Tandy TRS-80 Color Computer. I got it with the 64k I got above.
  9. This is a bit of a followup to a post I already made about a power supply I was working on. Anyway I was able to get the adam to run by just running my own wires to the db9 connector instead of using a serial cable. I now have the problem that the thing only runs if I hold down one of the reset switches and even then the picture is noisy, and the channel 3/4 switch seems to do nothing. If anyone knows what's going on here let me know please. I want my desk space back

  12. For years now I've been hoping to see a series like this for various retro computing platforms (Atari 800, Apple II, TRS-80 Model III, Fujitsu FM7, C64, VIC-20, Atari ST, TI-99, SG-3000, X68000, Acorn, BBC Micro, Color Computer, PC-88, Spectrum, Adam, etc...). https://www.youtube.com/playlist?list=PLOT5j3ELi5BaSrb24fJEKvTqlRK4fg9wS In this case, it's for the Amiga. If others decide to make YouTube tutorial series' like this, please let me know. There are a bunch of platforms that I'd like to learn. And if someone can recommend a free video screen-capture utility that is Windows Vista compatible (and doesn't contain viruses), I may actually do more of these. Oh, and maybe an app that can add captions since YouTube is no longer offering annotation and captioning services as part of their site tools.
  13. Has anyone been to the American Computer Museum in Bozeman, Montana? I am going on a road trip from Seattle to Calgary and thought about taking a side trip there. However, another part of me really wants to go to Glacier National Park. I have to choose one or the other. What would really help me is to know how it compares to the Computer History Museum in Silicon Valley. I have been to the Computer History Museum, so I was wondering if I would basically see the same thing in the American Computer Museum. Any advice would be appreciated. Thanks in advance.
  14. MAME 0.213 It's really about time we released MAME 0.213, with more of everything we know you all love. First of all, we’re proud to present support for the first Hegener + Glaser product: the “brikett” chess computers, Mephisto, Mephisto II and Mephisto III. As you can probably guess, there’s an addition from Nintendo’s Game & Watch line. This month it’s Mario’s Bombs Away. On a related note, we’ve also added Elektronika’s Kosmicheskiy Most, exported as Space Bridge, which is an unlicensed total conversion of the Game & Watch title Fire. If you haven’t played any of the handheld LCD games in MAME, you’re missing something special – they look superb with external scanned and traced artwork. On the arcade side, we’ve added The Destroyer From Jail (a rare Philko game), and alternate regional versions of Block Out and Super Shanghai Dragon’s Eye. The CD for Simpsons Bowling has been re-dumped, resolving some long-standing issues. With its protection microcontroller dumped and emulated, Birdie Try is now fully playable. Protection microcontrollers for The Deep and Last Mission have also been dumped and emulated. Improvements to Seibu hardware emulation mean Banpresto’s SD Gundam Sangokushi Rainbow Tairiku Senki is now playable, and sprite priorities in Seibu Cup Soccer have been improved. In computer emulation, two interesting DOS compatible machines based on the Intel 80186 CPU are now working: the Mindset Personal Computer, and the Dulmont Magnum. The Apple II software lists have been updated to include almost all known clean cracks and original flux dumps, and the Apple II gameport ComputerEyes frame grabber is now emulated. We’ve received a series of submissions that greatly improve emulation of the SWTPC S/09 and SS-30 bus cards. On the SGI front, the 4D/20 now has fully-working IRIX 4.0.5 via serial console, and a whole host of improvements have gone into the Indy “Newport” graphics board emulation. Finally, MAME now supports HDI, 2MG and raw hard disk image files. As always, you can get the source and Windows binary packages from the download page.
  15. Hi all, I'm looking into getting a floppy drive for my 99, but I don't want to break the bank for one. Is there anywhere (or any other type of drive) that I could get? What are all your suggestions? Thanks!
  16. Just wondering the what you guys would think the value of this system would be? I have a change to pick one up with the Basic Language Cart as well as a few others, with all hook up. Was a TI guy in the 80's and went PC in the 90's. Been been getting back into the TI as of late and was thinking of adding another retro computer. Thanks, Robb
  17. The Computer Spiele Museum visit. The Computerspielemuseum Berlin (Computer Games Museum Berlin) was founded in 1997. From 1997 to 2000, it had a permanent exhibition in Berlin. Afterwards, it became an online only museum. In 2011, it reopened its permanent exhibition in Berlin’s neighborhood of Friedrichshain. During the first month of its permanent exhibition, it had 12,000 visitors. Some pictures of this great museum : http://gameplayerspecial.com/2012/08/23/computer-spiele-museum-computer-game-museum/ Thanks.
  18. So there is a good deal on a 1200xl locally. $60 obo complete in the box along with a basic programming cart,rf cords,and the power supply. Issue is I'm only really interested in playing games on it and I have heard that it has compatibility issues. What do you think?
  19. The poster for the upcoming Gameplay: The Story of the Videogame Revolution documentary film is now ready, and shown below. When the Website is ready, I'll post again, and also once distribution details for this year are finalized. The film, which is based on the Vintage Games series of books by me and Matt Barton (we're also writers and producers on the film), covers the history of videogames from the perspective of those who made it happen. Those interviewed include Nolan Bushnell, John Romero, Todd Howard, Daniel Murray, Darion Lowenstein, Eric Lindstrom, David Crane, and many, many more. The narrator is Cain Devore. The film also has a Facebook and Google+ presence, although Armchair Arcade is still a great place to find out new details (in fact, here's the same thing as a blog post there so you can see the PDF).
  20. Commodore 64C - The new member of my commodore collection. Hello ! Today I received the newest member of my collection, the Commodore 64C with 1571 and Jiffy DOS drive. http://gameplayerspecial.com/2012/08/13/my-new-commodore-64c-unboxing-drive-1571-jiffydos/ Thanks !
