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

[Neil Morrison]

The early Coco I was indeed designed to use sets of defective 64K rams, 
either all upper or all lower half good. The TRS-80 Model I was similarly 
designed to use sets of defective 16K rams, either all upper or all lower 
half good. I never saw this done or heard of it being done in either case.
