AtariLeaf Posted January 23, 2017 Share Posted January 23, 2017 This has gotten me thinking as someone on the facebook recently had a dead GIME in their coco 3. As we all know, these are custom chips that Tandy created for the Coco 3. You can't just buy a spare online somewhere like you can parts for other classic consoles or computers. The only alternative is to cannibalize another coco 3. I wonder (1) what the failure rate specifically for the GIME chip is and (2) what modern replacement may need to be developed to keep these systems running. I have 5 coco 3's and the main reason I bought 5 over the years is that I looked at it as not,just buying another coco 3, but another spare GIME chip. Should I and other coco 3 users be worried that their beloved systems are just ticking time bombs? Quote Link to comment Share on other sites More sharing options...
Turbo-Torch Posted January 24, 2017 Share Posted January 24, 2017 Gime? What's a gime?...ohhh, a gime! Bonus points to anyone who gets that reference. Radio Shack used to have National Parts which had individual components for everything they sold. All my local stores had an AS IS section where you could buy faulty returns for next to nothing (typically $1 to $5). I'd stop in once or twice a week to pick up new items ranging from cordless phones, CBs, car amps, stereos etc. Those items which were actually broken (many were fine) were very easy to get parts for. All you needed was the model of the unit and the failed component # that was inked onto the circuit board. Go back to the store and they'd order it from National Parts and you'd have it in a few days. The prices were very reasonable too. National Parts is probably long gone but that stock had to go somewhere. There are probably 1000+ GIME chips along with components for every computer Tandy ever made stashed away...just hopefully not in a landfill.

JamesD Posted February 8, 2017 Share Posted February 8, 2017 You could replace it with an FPGA or CPLD (depending on how large the code is) if you can find a socket adapter.I couldn't find a socket adapter of that size when I looked.

Stormtrooper of Death Posted February 23, 2017 Share Posted February 23, 2017 (edited) Your problem with the GIME chips is a lot like the Atari 8bit POKEY chip that is also getting rare (=not being produced since a long,long time) . Also a custom Atari chip... Edited February 23, 2017 by Stormtrooper of Death 1 Quote Link to comment Share on other sites More sharing options...
