[Coco] I've killed my CoCo3

[Michael E Kent]

If the machine is declared DOA, keep in mind that the GIME chip and other parts are valuable and coveted for repairs, even the keyboard is useful.  There are several DOA Coco3s on eBay right now that could be repaired with donor parts from your machine.

It's a tragic thing to hear when we lose a good CoCo, and I'm very sorry for your loss.
I'm not sure if there is a "way back" from that, but if there is, I'm sure someone here will be able to share that.

While at Tandy Assembly, I was able to video tape Richard Lorbiesky perform a full CPU transplant, and the process is fasinating, and he did use a "solder sucker gun", not sure if that's the official name, but that made the process go very quick and easy.

I will try and get this video uploaded today, because it's a pretty cool project to do, but way beyond my current physical skill set.
