Hi,
I'm sitting over the schematics of a DISK II
Controller interface trying to understand the
finite state machine consisting of the 323,P6,
174, and NS9334 (+several glue).
Does someone have the contents of the PROM? I
obtained the PROM datasheet from www.ti.com
naming the pins of the PROM....
However, I would prefer not to replace the PROM
on my DISK II card and build a interface to read
it out if someone already did it....
Best regards,
Hans
