[Coco] 26-3127B <-> 26-3134B Coco 2Bs

[Bruce W. Calkins]

Al's covered that question.  I suppose IF and that is a BIG IF you cut the 
approiate chip and address select lines and added a Banker circuit you might 
be able to go to 128k.  However I'd more quickly use the piggyback route 
myself.

FWIW; They are in storage since any applicable CoCo 2s got 64 by 4 chips 
from upgraded CoCo 3s which gives them shorter and less fragile wiring runs.
