ApolloBoy Posted July 6, 2022 Share Posted July 6, 2022 I recently picked up a ColecoVision EM 1 that was non-working, and after some chip swapping I've determined that it most likely has a faulty TIA chip. I'd rather not cannibalize a 2600 so I was wondering if anyone here happens to have a spare. Quote Link to comment Share on other sites More sharing options...
Osgeld Posted July 7, 2022 Share Posted July 7, 2022 seems like they have been harder to get lately, I have a wanted thread for a tia that never really got resolved ... and I ended up buying a pair of busted 2600's just to patch together a system Quote Link to comment Share on other sites More sharing options...
SoundGammon Posted July 7, 2022 Share Posted July 7, 2022 I think the TIA chip in the EM 1 is a custom chip and one from a 2600 won't just plug in! The pin-outs are different. I have about 3 EM 1s somewhere down in the basement if you need one. Quote Link to comment Share on other sites More sharing options...

It seems that you're right, I did a little more homework and it looks like it's a different pinout than a regular TIA. I'll send you a PM shortly.
