[Coco] Model No. 26-3127B motherboard

[Mike Pepe]

Alan:

1: That's a 64K memory expansion card.

2: a pair of 16kx4 chips (41416 or similar) are what go in the now empty
sockets

3: the 64k/128k jumpers refer to the ROM size. 64 kilobit (8k x 8) for
standard color basic, 128 kilobit (16k x 8) for extended basic
