i have here a PDP8/E with a defective M8300
Mayjor Register board. The
problem is a DEC8271 shift register that is used for bit 0 - 3 in
program counter register.
Do anyone know a modern? equivalent for the DEC8271?
As Eric said, there doesn't seem to be an exact modern equivalent.
You could try eBay auction #161031743575 (no connection to the seller).
A superficial examination of the data sheets suggests that the 74178 might
be a replacement, but I don't have time to compare the specs at the moment.
