[Coco] RE: [Color Computer] Looking for a Coco I 64k?

[Bruce W. Calkins]

As I recall, ALL memory was socketed until the CoCo 2 in 64k.  4k and 
16k memory were never socketed.  I'd love to see an original board to 
disprove that though.

Worked the first time, never had a problem with it.  I think I got the upgrade instructions from an issue of Hot Coco.  23 years ago, can't remember that well...
