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.
