Hi,
This is quite urgent.
Can someone who has the earlier version of the Central Point Option Board
(also known as Copy II PC Option Board) please type up the part numbers of
all chips on the card? Or scan the card at a decent resolution so all chip
markings are legible.
I want to get datasheets for as many of the ICs on the card as possible.
Assuming some are not just simple TTL chips, the best place to look for these
would be the FreeTradeZone web site. As mentioned a few days ago, that will no
longer be accessible for free in a few days time.
(I don't have an older Option Board yet. I want to get info on the ICs it uses
for a possible future reverse-engineering effort, to figure out how the card
works, and allow low-level disk-imaging software to be written.)
