This is what I have read from the CBUG newsletters.  Only a certain 
"white" PLA will allow the original 8088 co-processor from the Commodore 
labs to work, and only on the high-profile B's.

I have only tried on these systems.  You can't fit the co-processor 
into a low-profile system anyway, too big.   I am guessing that we're 
not talking about the same co-processor card.
