  1. I have a NTSC 800XL with an NTSC GTIA and a PAL Antic installed. I edited the game using Omnivore and changed value $D014 to $D013. It is now playing nicely on my 800xl.
  2. I wrote an AI pong game with Batari Basic some time ago that I just called Tennis. Press the player 2 button to start a game against the CPU. If you are using Stella, F3-F8 change paddle and ball size as well as speed and trajectory.
  3. I installed a USB power jack on my Atari 7800 using a step up converter. Works great. Your USB 5v power source will need at least 2 amps. At least for the 7800. https://www.amazon.com/Converter-Yeeco-Regulator-Ajustable-Transformer/dp/B011EBSKK0
  4. Inverse Atari key is (~). CTRL ' = (`). As the Montezuma said, CTRL 9,0 = {}.
  5. I opened up my 850 and rewired the rs232 port to make it compatible with the standard IBM pinout. No more adapter cables needed.
  6. I think the Atari 8bit has some promise. These are some pretty impressive Super Mario Bros. demos that were done some time ago. main.xex Super Mario (PAL-Blending)PAL.xex Super Mario (Probe).xex Super Mario 3 PAL (1).atr
  7. It takes a 9v power supply. I'm pretty sure it is the same power supply that the 1050 disk drive uses.
  8. It fits in the PR Connection box. I am using a PI Zero. Very small. Only about a 3rd the size of a credit card.The GPIO is permanently soldered to the rs232 port.
  9. I use a Raspberry Pi Zero as a Hayes modem emulator over my Atari 850 or ICD P.R Connection. There is an app called Tcpser that will make the PI behave like a Hayes compatible modem. The Atari just sees it as a modem. Since the PI is wireless, you can be online anywhere. Pair it to your phone or hot spot. Here is an example of one working on an Apple II. Of course, for an Atari you will also need something like the 850 or PR Connection. https://www.insentricity.com/a.cl/215/putting-your-retro-computer-on-the-line I have my PI permanently soldered inside of my PR Connection box. I never remove it.
  10. I'm in the Charlotte, NC area. But, frequently in Asheboro, NC.
  11. I have an 800xl NTSC with a PAL ANTIC installed. It loads and plays correctly from SIDE2. Great game!
  12. tjlazer is referring to Mario Bros. Arcade available here, http://atariage.com/forums/topic/267300-my-8-bit-computer-5200-hacks/?p=3797543. I had looked for the same and only found the .car file. I was hoping it could be converted to xex someday so I could play it from SIDE2.
  13. I had an old Dell SK-8135 in bad condition. I reused the cups in my 130XE keyboard. They did the trick. Feels like a real keyboard now. Gives a nice pop back feel.
  14. Wow! I have FF on the 7800 too. I'm lucky if I get past 5 or 6 screens before game over. BTW, Howdy from Concord, NC.
  15. http://atariage.com/forums/topic/281372-scramble-5200/ (playsoft) just released an amazing port of Scramble for the 5200. I really hope he ports this to the 8bit.
  16. I did something like this with the PI. Here is my post with some details. http://atariage.com/forums/topic/280099-weird-possibly-idea/?do=findComment&comment=4057945
  17. I have tried to find an NTSC version of NUMEN, but no luck. However, NUMEN will work on an NTSC Atari if the NTSC GTIA is replaced with a PAL GTIA. This version of NUMEN works on my iPhone.
  18. Here are some demos that I tested in Altirra set as an NTSC Atari 400 48k. I hope they work. demos400ntsc.zip
  19. That is a bit outside of my abilities. But, it would be nice not to depend on an 850 or PR C for rs232. If someone could do that, the PI could be mounted inside of the Atari chassis getting 5v power off of the main board. Just as a proof of concept, I have had the PI and Atari running off of a 5v battery with a portable tv. I paired it to my phone for internet. It worked great.
  20. I have been doing something like this using a Raspberry Pi that is connected wirelessly to the internet. I use a PR Connection serial port plugged into a little ttl to 232 board that is plugged in the PI GPIO. On the open port on the PR Connection, I have an SIO2USB connected and plugged in to a free UBS port on the PI. From here, I direct connect to the PI from the Atari using ICET128. I can then mount ATR files using command line using an app called SIO2BSD, loaded on the PI. Reboot the Atari with the SIDE2 cart out and the ATR will load via the SIO2USB. On the PI I also have a text web browser installed called W3M. With this, I would go online and download new ATRs, usually from atarimania.com or just browse the web. You can mount files from the atari with a command like: (sio2bsd -s /dev/ttyUSB0 -f PacMan.atr) Here are a couple of images on the Atari in action. The first one is the Atari looking at Atariage.com. The 2nd one is my board with the PI, PR Connection, max3232 and SIO2USB packed together.
  21. It looks like there isn't much movement on this Phoenix port. But, these are some nice images if it ever comes to fruition. https://ataritools.fr.gd/1-_-PHOENIX-PROJECT.htm
  22. The VBXE is a true video upgrade from the GTIA/ANTIC. Device info: RGB output providing crisp clear picture using LCD TV or RGB monitor up to 1024 colors on screen from 21 bit palette graphics resolution up to 640x480i (640x240p) in 64 colours, 320x240p in 1024 colours, and 160x240p in 1024 true 80 char mode for text display blitter with 7 modes of operations capable of zooming displayed data, transparency, collision detection and many other features full downward compatible with GTIA chip and many, many more https://lotharek.pl/productdetail.php?id=53
  23. I tried this on my Atari last night using APE over SIO2PC. I can't get past the "Press Return to Continue:" screen. There is a note above it stating: " If you cannot get past this opening screen, you must use a different version of the "telnet" program--some of the ones for IBM compatible PC's have a bug that prevents proper connection. " I was using ICET128 and ANSIVBXE terminal emulators. Has anyone had success getting through the first screen?
  24. The Sophia would be a cheaper alternative and easier to install if your goal is only to connect it to a modern monitor or tv. I have a VBXL in my 800xl. I have it running through a GBS-8220 model RGB to VGA converter. Thus, I have my Atari plugged in to a Dell monitor through VGA. It is a pretty clean image.
