 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.
