  1. I have a prototype ALF Music Card MC1 clone I am building. Does anyone know where I can get the software for it? On YouTube, I have seen some players playing music with it. If I could find that, it would be great. Also, any general information on programming the card would be helpful. I'm not finding much about it except for some crude schematics I based my design on. Thanks!
  2. So I just recently bought a Booti card (haven't received it yet) and just learned that the CFFA3000 is back in stock (for a bit, anyway). My biggest question is what does the $250 CFFA3000 give you that the $55 Booti doesn't? Thanks.
  3. So, I finished the upgrade for now. Getting nice DVI/VGA output awaiting the day I get a new HDMI monitor. I'm not so great with cutting holes in plastic but I sorta like the end result. It's a tad crooked on the inside. It would be nice if the DVI board were redesigned a little to fit the existing holes of the RF modulator. Especially the end towards the case. Anyway, I'm happy with the result.
  4. Well, the 28C64B's are several years old. They are legit because I got them as free samples directly from Atmel. My 28C256's are also legit (and within 2-3 years old) as I bought them from Mouser. I rarely purchase chips from eBay/AliExpress unless it's something like a VDP or GAL (even still, I try to use the same eBay seller). Funny thing...damn thing started working again. I did flash the firmware to the newest version. So fingers crossed this will continue to work. When things work, then don't work, then work again...well, that makes me nervous. I may try the multimeter test as well. Thanks everyone for the help.
  5. I have a MiniPro TL866CS that I've had for years. I've noticed today that all of my EEPROMS won't program 95% of the time. They read just fine. I have some 28C256's and some 28C64's. I've tried about 10 different ones and all seem to read OK. But only one 28C256 will program OK and it only does it about 1 out of 20 times. I even decided to fill the chips with a specific number (42) and it fails. BTW, it SAYS it programs just fine. But all validations fail. Even the all "42"'s fail. When I fill it with 42 and read back, it has a different number like 53. So, do you think it's time for a new programmer or is there something maybe I can check? Thanks for any tips.
  6. What @mytek said. However, sunburn is quite common. LOL
  7. Yeah, DVI is great. I like it better than HDMI because it has no license restrictions (same for VGA). My thing is, I just don't have a DVI monitor and since I have about 15 monitors total, don't know if I have the room for another. lol Too bad the board couldn't be sold MINUS the HDMI and include audio. That way, people like myself could just buy the HDMI jack myself and solder it on.
  8. Well, there's no pink strip on mine. Only real issue I saw was jailbars but it wasn't so bad I can't live with it. Anyway, tonight is the night I cut the hole and mount the DVI board. It's nice having either VGA, DVI or HDMI as an option on my 800XL.
  9. It works! I bought this adapter: https://www.amazon.com/gp/product/B08YRF3YLQ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 And it works great. I do see some jailbars in the image. I cannot confirm if it's my monitor or not. But I'm still happy. TI-99/4A has VGA and now so does my 800XL. 🙂
  10. Well, I already bought the Sophia 2 (which is what I wanted). I have a truckload of cheap, VGA/LCD monitors. I have two HDMI monitors but they are my primary monitors where I have no room for an Atari on the desk. Also, I have a really good ViewSonic 17" CRT (VGA) that looks awesome. So lots of incentive for VGA with me. I guess I could break down and buy another HDMI monitor. Just need to make sure it has VGA on it (I also have an F18A which requires VGA).
  11. That's actually what I was getting at. In fact, it would be really neat if we had a new daughter card for HMDI that also had inputs for an audio pass-through.
  12. Thanks! That's what I will do. BTW, I did a little more research and the DVI to VGA I have is missing a lot of pins. Whereas the DVI to HDMI converter I have is a 24+1 (or something like that). Basically, all of the pins are there.
  13. Hello all. I finally got around to installing my Sophia 2 into my 800XL. I also did the S-Video mod some time ago. With Sophia 2 installed, the S-Video still works (which is awesome). However, I don't have any actual DVI monitors. I have plenty VGA and a couple HDMI's. Before I go drilling the DVI connector into the case, I was wondering if there was a replacement cable and HDMI board instead? I was able to use a DVI to HDMI converter and that worked (although, it was flaky and when I moved the cable the image would go out). The DVI to VGA adapter I have doesn't work at all. Not sure why on that one. So what do you suggest? 1) Hope there is a true HDMI solution? 2) Get a better DVI to VGA adapter? 3) Get a DVI monitor? 4) Something else? Thanks!
  14. In other news, Woz tweets how Nox Archaist can save two bytes by using four transistors and a tuning fork.
