Ruud,
I have one of the original 8088 co-processor card prototypes from
CBM's labs. TO make it work I also needed a compatible PLA chip
on the motherboard. Did Bo make an after-market card or does he
have an original? I don't think that the original 8088 co-processor
works on a newer 720 without further modifications of the 720. I
would like to learn more about that.
If you're interested I can put together all of my notes and pictures
into a web page to illustrate the system. I have spent a lot of
time tracking down all of the bits and pieces. Recently I did an
exhibit of the B systems at the VCF 3.0 East.
