  3. Hi; So I hauled out my 8-bit collection (that has been modded for various reasons back when I used it heavily back in the '90s). I have forgotten soooo much! This 8-bit stuff got me through a dissertation, online database searching and early attempts at running a profession-related BBS before the Internet was ubiquitous. Current problem. I'm trying to efficiently figure out what to do to resurrect a 130XE that currently only boots to a blank green screen. I noted that a different computer (Also Atari 8-bit) booted to green screen when the ribbon cable for the keyboard was badly inserted (a corner was folded over itself...straightening that out allowed it to boot correctly, but that was not the problem with the unit at hand). First question: I have a pretty horrid/beat up 65XE that I was thinking I might scavenge for parts/chips, BUT other than memory are the 65XE chips the same as the 130XE? Next question: Is there a step-by-step logical process for teasing out the most efficient process for diagnosing/repairing the green screen issue? Thanks Stuff I have on hand... CSS Black Box with Floppy Board (Bob Puff was my main go-to guy back in the day!) SpartaDOS X with R-time-8 cartridge 130XE with 320 RAM upgrade/Multiplexer OS (in good working order) 130XE with a ROM board/switch that can switch/boot between 3 different chips (this is the machine with the problem) 800XL standard/good working order 65XE with horrid case and keyboard with many dead keys (I might be brave/foolhardy enough to try and desolder this for parts). 1050 disk drive XF551 disk drives (2) Hard drive with various Sparta/MyDOS boot partitions and utilities. Various game cartridges and 8-bit software mostly on 5.25 disks.
  4. Why do 16-bit light guns look so ridiculous? SNES Super Scope: Sega Menacer: Compared to these 8-bit offerings: Famicom Revolver: NES Gray Zapper: NES Orange Zapper: SMS Light Phaser: Atari XG-1: I mean, I can understand that in the 90s, video game and toy makers were pressured to make guns look unrealistic as possible, but come on, the Super Scope and Menacer just look absolutely ridiculous. Even later gen systems like the PS1 Namco Guncon look normal in comparison. What's worse, with all the modular detachable pieces that can get lost over the years, it's nearly impossible to find one complete.
  5. 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.
  6. 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.
  7. 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.

    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.
  10. 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

  12. 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
  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. 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

  17. 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.
  18. 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.
  19. MEMOIRS OF A NOVELTY ACCOUNT VOL. III, ISSUE III When a coworker approached me about two and a half months ago asking if I would compose the music for his video game, I was skeptical. After all, I had never seen a serious development project. Upon looking into it, however, I discovered that his ideas are full of potential and his drive to get things done is exceptional. In other words, I fully believe in his project, and am helping to the best of my ability. Since I am (or was, sorry...) active in the AtariAge community, I thought that an announcement here might help the game gather some traction. I know you all appreciate the essentials of good game design, and some of you are even programmers yourselves. I can attest that my coworker is a competent programmer and a lot of work has already been done on the project, technical and otherwise. Although the scandal involving the Ataribox crowdfunding campaign had soured me to the idea somewhat, I believe this is an entirely different situation. We already have material -- whether we're going to reveal it, though, is up to the community and the amount of support we receive. I hold a deep respect for the moderators and users of AtariAge, and I trust that this can be a success for all of us. I am posting a link to the GoFundMe page for our game, "They Keep Coming". Please visit and consider making a donation, and also feel free to comment and ask questions. I will be sure to provide updates on this blog when it is pertinent. Thank you. https://www.gofundme.com/They-keep-coming

  25. ======================== 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.
