  1. After purchasing a TL866ii just for this project and successfully flashing the memory GAL and BASIC ROM, I was very disappointed to find this device won't program the PIC for the TransKey II expansion. If anyone here is able and willing to program this chip for me (I'll gladly pay for your time and return postage), please PM me.
  2. I don't see where to log in on the new website.. and I think I may have accidentally let my membership lapse. How do I correct this?
  3. I remember seeing the pictures of the cart and box, but I never saw a preorder/ order thread. Are copies still available?
  4. When is this masterpiece of a game going to see a cartridge release?
  5. Progress! I suspected a bad FREDDIE since this was the only donor chip I could not test. A replacement from Best Electronics was ordered and my board now boots up as it should! My stock video is quite blurry, similar to what @Santyago is experiencing, but UAV is nice and crisp, so I'm not going to worry about it. After testing with jumpers in U34 socket at first, I have now flashed my GAL and installed the memory expansion. All is still happy.
  6. I've left the memory upgrade out for now because I do not have a programmer for the GAL (or the PIC, or the BASIC ROM) yet. I have the chips. Hoping to get this up and running in its most basic form first. I have not tried UAV, and there is no sound at this point. Thank you for your help!
  7. The blue box in the second picture is probably a homemade SIO2PC device. Used to connect an Atari to a serial port on a PC running APE or similar software. Allows for file transfer, use of the PC's printers, and more.
  8. I have also tried this, no change to my board. I have re-verified all the salvaged chips (except FREDDIE, might order one). My RAM chips are KM41464AP-12, not -10 as suggested. Could this be my issue? @Dropcheck Did you ever get your board functional? Did you end up using a crystal, or make the oscillator work?
  9. If I were in your shoes, I would keep an 800 and an 800XL. Depending on your nostalgic memories, of course.. Strictly practically, an 800 with Incognito upgrade, if that's within your wheelhouse.
  10. Games highlited in blue will only work on the 400/800... Games in orange will work on any machine with at least 48K.. Games in red require an XL or XE with at least 64K. The rest should be good on any A8 with at least 16K. It's late and I've had a few drinks... Take this with a grain of salt and please, other members correct me if I'm wrong.
  11. Thank you for the quick response.. Same results with those two jumpers added.
  12. Okay, reaching out for a little troubleshooting help. My first power-on was less than successful. My board is currently missing the four passives in the lower left corner (I'm using an oscillator instead of crystal) and the 14 components omitted for NTSC. I have not yet installed the TK-II chip, the three chips for the memory expansion, or the BASIC ROM. Video config is for standard. When I first powered on, I was greeted with this screen: I reseated all the chips, and realized I had accidentally placed the unneeded LS74 where the LS08 belongs. I corrected this and gave the board a once-over for solder bridges, etc.. It now powers on to a blank white screen. Could I have done damage having the incorrect chip in U18 initially? Any suggestions would be most welcome, my troubleshooting skills are not particularly strong. All the Atari VLSI chips were verified working, except for FREDDIE, which I was unable to test. Crossing my fingers for him! EDIT: added picture of my board's current state:
  13. My copy had the exceptionally good timing of arriving today, my birthday! Will be making time to enjoy it this evening. I too have just barely tried the game in emulation to wait for the real deal. Postmark was the 9th... nine days is perfectly reasonable international shipping time, especially for only US$7.
  14. Thank you for the info, but I will find a 3K. I just want to be sure that I'm correct in concluding the board calls for 16, but the Mouser basket was for 15. I have other parts left over (I'm building mine as NTSC and using an oscillator rather than a crystal) and I want to be sure I didn't misplace a 3K.
  15. Quick question regarding the bill of materials: Finally started assembling my board this week (vacation time!) and I ended up with an empty 3K resistor space. The BOM shows a quantity of 15, and this was what I received from Mouser. However when I carefully examine the layout diagram, I count 16 3K resistors required. Has anyone else noticed this? Or did I make an error somewhere? It's not a big deal, I can replace the missing resistor. Just want to make sure this is the issue before I proceed.
