: 13.  AII Memory Expansion.  Apple Computer, 1985.  Currently has 16
: memory chips on it.  There are spaces for 16 more.  How much RAM would
: this card accommodate?  One set of memory chips say "MCM6256BP10" on
: first line; the other set say "KM41256AP-12" on the first line.  Are
: these chips still obtainable?

This sounds like a board that I found for my IIe sometime back.  This is
clearly a memory expansion board, and it behaves as a ProDOS volume when
you boot ProDOS.  As for memory, I have found that pulling the RAM out of
old ATs and XTs is the cheapest path.  I was able to upgrade this card
from 256k (the condition which the card was found in) to 1Mb, which was
perfect for running my old version of AppleWorks. 

This is a very nice board, but I have always been left wondering: can 
this memory boon (for a IIe at least!) be used by DOS 3.3 programs?
