    I'll be around that Sunday and can stay after the show to help with teardown!

    I'm going to Portland too! I'm not getting in until Friday afternoon, but I'm happy to help with pack-up at the end of Sunday. Ben Combee bcombee Austin, TX

    Looking at the TIA chip pin out (from http://atarihq.com/danb/tia.shtml), there are no RGB signals to use. The TIA directly outputs a color signal and three luma signals, so S-Video is the best video quality you can get out of it. Any RGB circuit would be decoding the baseband video signal in much the same way that a monitor would.

    I just made my order for the sale. This bunch of 2600 homebrews came in just over $200 after the 10% off: Assembloids Stay Frosty 2 Wall Jump Ninja Super Cobra Arcade Scramble Space Cactus Canyon I ordered Sheep It Up! for the bonus game after playing the ROM on my Retron 77 and really enjoying it.

    I suspect it's a hardware issue. The analog-to-digital converter works by putting the pot between the high voltage, and a fixed resistor connected to ground. This makes a voltage divider; the voltage level at that midpoint is directly based on the value of the pot. If you have a mismatch between the fixed resistor and the range of the pot, then there won't be sufficient voltage levels to get a lot of different ADC readings.

    There's info in the pinned thread:

    I recently got a Retron 77 which came with the 2nd version of it's "Trooper" joystick. It looks like a CX10/CX40, but has two fire buttons (either corner, fired the same) and faceted corners for your palm to rest. It also has an embedded strain relief and a really long cable. So far, I've found it to be really great. I know people had issues with the longevity of their initial run of joysticks, but I've not had any issues with this one yet. https://www.amazon.com/Hyperkin-Trooper-Controller-not-machine-specific/dp/B07M5HYTZL

    I did find some 2600 carts that I needed from the excellent Ianoid, and I got a couple of old BASIC type-in game books from the Game Over Clearance section, but that was it for retro content for me. (I also seriously considered getting a Tandy 102 that was for sale, but decided I had enough projects) I picked up a screen-printed t-shirt that was a mashup of Star Wars and Galaga. This was my first time watching the "This Controller Sucks" panel, and I liked it, but I left during the book author panel as I just wasn't hearing anything that exciting. I liked the old computer content -- the Apple II and Mac gallery with the old games was great, as was the bitgod booth and the Irata Online people. But it really feels more like a local show than something trying to be one of the big ones. It did redouble my resolve to go to PRGE this year, though; that's the closest show to the feel of the old Classic Game Expo shows in Las Vegas of the ones I've visited.

    I'm going on Saturday for the panels. I'm getting disappointed with the show's inability to attract many speakers; maybe next year, if it happens, I'll apply to do a talk about Atari 2600 homebrew.

    The Activision Blast should have come with a small USB-A to micro-USB cable. Most TVs with HDMI ports also have a USB port, and people usually plug it into the TV's USB port to supply power.

    Just noticed this topic... since i live here in Austin, I definitely want to come to some of the event. I've not done much TI99-4/A hacking, but I think I do still have a system and some carts in my storage. I was very impressed with the display of recent TI work I saw at the Vintage Computer Fest SE in Atlanta a few months ago.
  12. bcombee
    IIRC, you can also plug a Colecovision controller into the 2600 and use that with Omega Race, with the two side buttons acting as the main fire button and booster.

    This was my first time seeing what the latest TI homebrew could do and I found it very impressive. Alas, I'm terrible at the game, as proven by me losing all my Dirks about four screens in.

    There look to be a lot of Atari 8-bit activities planned for Vintage Computer Faire Southeast coming up at the end of the month in Atlanta. See http://vcfed.org/wp/festivals/otherevents/vintage-computer-festival-southeast/vcf-se-exhibits/for exhibits and links for more info.

    Sorry for the very long delay. I'd forgotten about this until I got notified by a mention and finally got to digging into my collection this afternoon. This is a CamScanner version, I'll try to get the pages scanned with a real scanner soon. Also, a lot of the pages at the end had been damaged by inter-page xerographic transfer over the years, but it's mostly still readable. https://archive.org/details/Edit6502Manual

    There are good compatibility lists for Flashback versions posted here on AtariAge. See http://atariage.com/forums/topic/258970-atari-flashback-portable-faq-and-compatibility-list/and http://atariage.com/forums/topic/285118-atari-flashback-9-compatibility-list/ for discussions.

    That sounds like Telegames. They had a warehouse in the Dallas area and also did game fulfillment for Radio Shack. They lost a lot on inventory in a tornado in the mid-1990s. The UK branch is still around. See http://www.telegames.co.uk/

    I wonder if the lack of "Casino" is due to "Atari Casino" being an ongoing business concern: https://www.atari.com/atari-casino/

    very nice, I'd never heard of the PORKY variant on the POKEY chip before reading that.

    My biggest request would be great versions of the core controls from classic arcade machines: joystick, trackball, and spinner. Arcade1Up really messed up with their sub-par spinner and low-resolution screen for the Atari vector game model.

    I've seen a few crowdfunded 2600 homebrew projects. I was one of the backers of the Star Castle homebrew project at https://www.kickstarter.com/projects/698159145/atari-2600-star-castle;I also tried to back https://www.kickstarter.com/projects/yuppicide/skull-island-a-puzzle-game-for-the-atari-2600, but it didn't reach its goal.

    I bought my copy of "Tax Avoiders" at a Kay Bee Toys around 1986.

    I got the FB 7 Gold Activision edition for Christmas, and so far, I've been pretty pleased. However, I hit one glitch that was very surprising. When playing Street Racer, the graphics for the player object in games 21 through 27 are a bit deformed. Any idea what's going on here? This seems like a pretty simple game to do something that would mess up emulation.

    The rarest cart from my original 80's collection was Tax Avoiders which I bought from a Kay-Bee Toys at Walnut Square Mall in Dalton, Georgia. I ended up getting a bunch of Datasoft Atari 8-bit computer games and books from that place too, as well as an original 70's Dungeons & Dragons players guide (before the AD&D or Basic edition sets).

    I made a skill last month for Amazon's Alexa service to test your knowledge of Atari 2600 trivia. So far, it looks like no one has actually used it. If you've got an Echo or similar device, try it out using the command "Alexa, play atari twenty six hundred trivia". There's about two dozen questions in its database, and I can refresh it with additional ones if there's any demand. I made it to try to qualify for Alexa developer swag, so it's not that advanced.
