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.

Rod
