Charlie, I retract my earlier statement upon receipt of new information. Here is what is printed on the PLA's for the CBM high profile systems that I have: 906114-04 CBM2 LP 4 PLA HIGH BOY (known to work with the 8088 co-processor in a B700 prototype) 906114-05 HIGH BOY 62E5 (found in 3 CBM 256-80 systems; 2 with and one without with the 8088 co-processor) Given the evidence the 906114-05 will work in the non 8088 CBM 256-80 and this is the PLA you want. I do not have any systems with the -01, I was mistaken. Thus I can't say that the -01 will help you. Bill Bill Degnan wrote: > I can check one of mine to see what's in there.
