After successfully repairing the G231 module of the MM11-L set I continued
with the next one. This one was not able to access addresses ending 0100
(binary). Luckily it was not the transistors arrays that were bad but the
selector chip. A Signetics N8251 chip.
I found a source on ebay at $4.95 each plus $13 shipping. A little bit to
much for my taste (although I could make an offer)
Anyone know of a cheaper source? I could use five or ten maybe.
