[Coco] [Color Computer] coco3 512K ram upgrade instructions

[John R. Hogerhuis]

Probably depends on the board...

I did it years ago for my coco3 and I think I had to just plug it in and
remove a capacitor (guess???...)

I needed the upgrade but alas after I put that damn thing in I had to
keep a little fan on top of the vent or it would overheat in about 30
minutes, at least here in sunny Southern California.

Are you trying to build your own or do you have one at hand?
