Hey all,
I picked up a Coleco Gemini clone recently, and after cleaning it up, reflowing all the solder points on the board and trying multiple games, the thing won't boot up, just a plain black screen. I did have a Colecovision with a bad RF modulator do the same thing, though it did still produce sound.. the gemini doesn't.
I'd like to try swapping some chips, though I'm pretty sure the CPU is bad (it's a 6502 like the 2600) And I'm wondering if anyone has some extra parts lying around. I could always disassemble my working Coleco expansion module which I assume has the same components, but I'd rather not.
