Hi
???????? Jerry Walker and I have an 11/34 under restoration.
We have run into a bit of a problem.
On the M8266 CPU control board a defective 7404 (E111) has killed a
bunch of the PROMs holding the microcode.
Does anybody have or can get images of the PROMs on this board so
replacement devices an be programmed.
