  1. ======================== EDIT: These items are no longer available. ======================== I recently came into possession of a decent sized collection of Atari gear. I grew up playing games and computing on similar Atari hardware so I'm somewhat familiar with the gear. Despite most of the gear being in excellent condition, it was destined for a trip to the electronics recycler. Recognizing the historical significance of the gear, I snatched it up to ensure that it can live on. I'm looking to sell and redistribute the gear to the community of enthusiasts here to ensure that it can be preserved and enjoyed for many more years. I spent many hours cataloging, testing hardware, photographing everything, and uploading photos. I've done my best to test and verify the functionality of most of the gear in this listing. You can see a list of everything that I have here: https://bit.ly/2qeRtAA Each item includes link to an imgur.com posting with photos. Most items also include a note about the condition of the item. Sorry, it's not the most convenient way to view everything in one shot but it works for me. I didn't include prices on my spreadsheet as I don't really have the time to determine the value of each item. In many ways, the value is really determined by the community here anyway. I would simply ask, if you would like to make an offer for anything on the list, make it a reasonable offer. Also, keep in mind there are shipping costs. Some of the larger items may incur significant shipping costs. I can certainly offer local pickup for anyone in my area. I'm located in south central Pennsylvania (York, PA area). https://goo.gl/maps/bWMy8WTxebmbAu54A Contact me via email or PM if you're interested.
  2. Anyone else going out to Classic Game Fest 2019 in Austin next week (July 27 & 28)? https://classicgamefest.com/ Rob and I will be there. In fact, we are going to have a booth this year as an indy game developer. We aren't selling anything, just showing our existing homebrew games to let people play them on real Atari 8-bit computer hardware and proper CRT monitors. We'll be demo'ing a few sneak peeks of things we've been working on too. Pretty cool stuff I think. And of course, more than anything else we'll be spreading the word about the amazingly active Atari 8-bit computer community and sharing info like how/where to get emulators, ROMs, classic games, new homebrews, and where to chat with others interested in this great hobby (like AtariAge.com of course !). Anyway, if you come out to Classic Game Fest next weekend, be sure to look for us... bitgod - "back in the good old days" -Eric
  3. 8-Bit buddies 8-Bit themed classic trading card stickers. 80 stickers in series 1. Preorder a box now on kickstarter http://www.kickstart...g-card-stickers
  4. Would there be any possible way to save files in cassette format on any Atari 8-bit computer emulator? I looked at many various emulators such as Altirra, A8E, Atari800win plus, etc, and I can't seem to find any option on any of those for what I'm trying to do.
  5. I know this is such a stretch but would there be any possible way to connect my Atari XF551 floppy disk drive to my Windows XP computer? I'd like to transfer Atari files to and from my PC. I really can't get an internal 5 1/4 floppy drive for the XP because they are just too pricey.
  6. Hello, I am keen to understand the inner workings of the game Crossfire for the Atari 8-bit computer. I find it to be a great game. I'm then going to try to port it slowly to all the other 8-bit computers, to learn how to program each old 80s micro. As a starting point, unlikely I know, does anyone have the original source code for the game Crossfire? If not, what would be the best software to disassemble this game? Thanks in advance, Nick

    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.
  9. 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.
  10. 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.
  11. Did you ever enjoy playing with food coloring? I did, many times. And that, plus my lifetime fascination with computers inspired me to come up with this blog. These are the 16 colors from the Intellivision, rendered in McCormick Food Coloring. It uses the standard red/yellow/green/blue, plus the neon purple/green/pink/blue, and black. Black: 8 parts Black Blue: 7 parts Blue, 1 part Red Red: 7 parts Red Tan: 2 parts Yellow, 1 part Red, 1 part Green Dark Green: 10 parts Green, 1 part Blue, 2 parts Black Green: 6 parts Green, 3 parts Yellow Yellow: 7 parts Yellow White: None Gray: 3 parts Black, 1 part Neon Purple Cyan: 3 parts Blue, 1 part Green Orange: 3 parts Yellow, 3 parts Red Brown: 7 parts Yellow, 6 parts Red, 6 parts Green Pink: 2 part Red, 1 part Neon Pink Light Blue: 1 part Neon Blue, 1 part Neon Purple Yellow-Green: 3 parts Yellow, 1 part Green Purple: 7 parts Red, 3 parts Blue And here's what they look like. Notice that they look kind of pastel, but that's because I used an opaque white paint as my medium. That does it for this segment. Next time, I'm going to render MSX colors using food coloring.
  12. Hey, I've released a new music album that contains 11 tracks written between 2010-2015 for Atari pokey sound chip (found in 8-bit Atari computers) with Raster Music Tracker. I thought this might interest a few folks here. Check it out: https://warlord.bandcamp.com/album/pokey-nights
  13. I've had a vcs and Intellivision for a long time now, I have the opportunity to buy a 400 computer with a bunch of game cartridges pretty cheap, but I've heard most of the 400/800 games availible were just 2600 games with graphical upgrades. I can see there are a few titles I don't have for any system, just wanted to ask what people think about it.
  14. My first transaction with AtariAge'r ACML went flawlessly and he was communicative throughout the process. He has my recommendation, and I look forward to any future purchases from him! --Tim

  16. Sold! SIDE Cartridge - Compact Flash Interface with 128MB SanDisk Card, up for sale on Ebay: eBay Auction -- Item Number: 322018817890
  17. okay, I saw this Amiga lightgun by actionware on ebay. It's still live: http://www.ebay.com/itm/NEW-Commodore-Amiga-Actionware-Light-Gun-Gray-Phaser-/272807926381?hash=item3f849e9a6d:g:NrAAAOSwutpZlGZK The gun looks exactly the same as my xg-1 lightgun. It even looks like there is red left from a peeled Atari sticker. Also, note the insane price (dunno... seller may just be delirious). I read somewhere that Actionware often repurposed and resold nintendo zappers with their lightgun games. I haven't seen evidence of this, but it sure as heck looks like that is what they did with the xg1 here. Now I'm wondering if the xg1 works on the Amiga and C64 or if there is some mod done to the guns. I have a c64 and I love lightgun games so having it work on another computer would be a plus. I'm also thinking... heck... maybe I should just do the mod and sell my xg1 for 120 bucks on ebay lol (okay not really but there may be others that might want to).

  19. I'm forwarding this on behalf of the SRCS admin because I think some people here could find this interesting. Come one, come all, to the Seattle Retro-Computing Society's regular monthly meeting! It will be held Saturday, August 25th from 11:30 AM to 5:00 PM. Do you do any of the following with old computers? Will you be near Seattle on Saturday? + Use, collect, and/or restore them + Play games on them + Write programs for them + Develop new hardware for them + Help other people do any of the above If your answer was "yes," then the SRCS is for you! We exist so you can show off your awesome stuff, bounce ideas off of fellow enthusiasts, and be inspired by one another's achievements, plans and aspirations. No idea is too big or too small, and we're not picky about what flavor of vintage machine you prefer! Come on down and tell us about it! The meetings are graciously hosted by the Living Computer Museum, which is gradually fitting out a computer museum in Seattle's SODO neighborhood. There will be refreshments, a Buy-Sell-Free-Trade table, and enough table space & power to set up anything you may want to show off! For further details, please see our web page at http://www.seattleretrocomputing.com/ and our mailing list at http://groups.google...attle-retrocomp . Hope to see you there!

  21. Good evening, everyone, I've been wondering, especially since Dropcheck has started inquiring about the Atari's PBI, what the advantages and disadvantages are between the PBI and the cartridge interface itself? What types of devices are best suited for one I/O platform over the other? I imagine from a modding perspective, a cartridge-based mod would have a much broader usability factor since not every Atari 8-bit has a PBI interface— but every Atari DOES have a cartridge port! For me, the primary drawback to these cartridge-based mods is that you only get to have one mod in play at a time. While there are a few pass-thru mods, the reality is that I don't see my utilizing the USB cartridge, the Bluetooth cartridge, and my SpartaDOSX cartridge with MacRorie's R-Time8 cartridge all in a single session, even though that would be something I totally seem myself utilizing. Yet all of these could be in simultaneous use, should someone develop an interface along the lines of the 1090, where the USB cartridge would become a PBI card-based solution, as would the Bluetooth cartridge— both operating through the PBI lines. And wouldn't it be convenient to be able to set something like the RapidUS to card-based, as well? However, with the 65/130XE and their ECI port, it seems like any 1090-like expansion solution would need to support a cartridge port. Anyhoo, I was just wondering what the technical advantages and disadvantages were between the PBI and the cartridge interface insofar as mod development is concerned...? Submitted for your perusal and consideration, Tim
  22. I'm putting together a kitted out ROM 03 Apple IIGS with 4MB of RAM. I've been trying to dig up a CFFA card to no avail. If anyone's got one they're willing to part with, shoot me a message
  23. Hi. I'm trying to extract music from one demo file (X-Files, The (1988-02-01)(SHP)(pl)[stereo]), all I get after extracting is 14 corrupted 1Kb files. I tried to use ATADIM, makeATR, Altirra, etc- no luck... Are there any chances to extract the sound files? Thanks in advance for any help P.S. The demo file itself- http://nitroroms.com/show/file-info/L45161/Atari_8Bit/X-Files,%20The%20(1988-02-01)(SHP)(Pl)[stereo].atr.html
  24. Heads up Atari 8-bit Fans! Former Atari employees Al Alcorn and Dan Kramer will be speaking at this year's "Atari Party" which will be held on Saturday June 14th in Atari's old stomping grounds of Sunnyvale California. The event is free to the public at the Sunnyvale Public Library. I've mentioned previously in other threads that Al Alcorn needs no introduction but for those who don't know, he was Atari employee #3 and the engineer who built Pong for Nolan Bushnell. He also worked on the 2600, the Cosmos, and plenty of other projects. He's briefly featured in the Steve Jobs bio film Jobs; he's the Atari manager who tells Steve Jobs he's an a$$hole. Alcorn later went on to become an Apple Fellow. If you are unfamiliar with Dan "The TrakBall Man" Kramer, he created the TrakBalls for both the 2600 and 5200 amongst many other projects back at Atari Inc. [the 2800, remote control joysticks, the Cosmos, etc]. There will be plenty of Atari 8-bit computer hardware present, as well as 16-bit STs, Atari arcade machines, and the various Atari game systems [as well as modern consoles, and PCs emulating classic Atari titles]. Bill Kendrick is looking for volunteers, especially people willing to bring hardware. Here's a link to the official website: http://www.newbreeds...tariparty/2014/
  25. I have an Atari 410 that is probably in need of new motor to run the mechanics. I did check to see if any of the bands had come loose but they were all in place. There does seem to be power going into the unit because it sends a garbled signal to my XE computer but the mechanics simply do not move to run the tape. Atari 410 test.mpg
