Are you interested in a physical card with the implementation of the 8088 coprocessor that you can plug into your existing CBM II or 
something else?

The cores are available for the 8088 (how good they are of course is another matter...) but not for the 6525 and 6526 chips (although 
these appear to fairly straightforward). I notice that the firmware and reverse-engineered schematics are available for this board. The 
8288 and 8284 are not straightforward, and the 8087 will be virtually impossible (without a significant amount of time and effort) 
although I rather suspect that most of the available software does not use the 8087 maths coprocessor as it was an expensive item back in 
those times.

I can't help thinking this is not going to be too easy - but let me chew it over for a while...
