  1. I would definitely do everything I can to repair and preserve this machine (assuming I could afford it, of course) but would be equally happy to see it go to someone like Ksarul or Fabrice. ☺️
  2. Possibly interested, messaged.
  3. Black screen w/ constant noise is a pretty common TI failure mode. First thing to try is pulling GROMs CD2156 and CD2157 and seeing if that changes anything. If there's no change, the fault most likely lies in one of the ROMs/SRAMs (the four wide chips right next to the CPU). Unfortunately neither the ROMs nor SRAMs are socketed, and there really isn't a good way to narrow down the problem without a logic analyzer or oscilloscope. Replacements for the SRAMs are easy to find on eBay, but ROMs would either need to be programmed yourself or harvested from another board.
  4. Agreed with wierd_w, it's a good idea to make sure it's not the TV before swapping chips. Pretty much all the computers from the time period were slightly-out of spec with their video signals, so the one you have might not display anything with the TI despite working with the C64. It's an especially good idea to rule out the TV first when dealing with the TI though; the "black screen" issue can be caused by a number of components (CPU, 9904, SRAM, ROMs, etc.) One question: with the sound chip installed, do you get any kind of noise when the computer is turned on?
  5. If you're able to see the title screen behind the black bars, but with no color, it's almost certainly a crystal problem. For something like that I see no point in buying another console; the crystal only has 2 pins and would probably take about 10 mins to swap.
  6. Black screen & cacophony usually isn't the VRAM; check the ROMs and 6810 SRAMs.
  7. This one is weird; normally when one of the VRAMs fails, the corresponding bit just gets stuck and garbles the entire screen. It could be the VRAM at U104 seeing the random ' " ' characters, otherwise I'd suspect the VDP.
  8. Disregard the above, I think I'm just going to opt for a Gotek instead.
  9. Repaired my A500 a while ago (previous owner mangled Fat Agnus Socket and pulled the ROM); now looking for a Workbench 1.3 disk so I can actually use it. Please PM me with any offers. Thanks!
  10. Agreed, there are more Commodore/Amiga forums than I can keep track of. The Apple folks have quite a few too; it's more just that us TI'ers don't have our own active forum outside AtariAge.
  11. The Attack is the only TI cart I've ever thrown out as I absolutely loathed it. Music and sound effects aren't great to say the least, gameplay is boring, and the graphics are retina-burning.
  12. The TI has a really nice port of Q*Bert. It seems to be moderately (?) common, but prices for that one can be a bit on the high side for TI carts. Parker Bros. also made ports of Frogger and Popeye for the TI, but I haven't played them so I don't know how good they are. Lastly, while not a game, if you ever get ahold of some kind of disk system (PEB, NanoPEB, etc.) Extended Basic is a really useful cartridge to have.
  13. While the TI's Atarisoft Pac Man is definitely better than the 2600 version, InfernalKeith really does have a point when he says it's clunky. Fastest level on the TI is about the same speed as the slowest level on the Atari 800 version I have, IIRC.
  14. The G3 Desktop's case (which it shares with the 7x00 series) is notoriously brittle. It's really easy to break little plastic tabs and other parts even if you're really gentle with it. Pretty much any Mac from that time period suffers from the same problem though, although the G3 Minitower seems to be a lot better than the Desktop in that regard.
