These are pretty rare, but each year more and more appear.  I am guessing 
that there are at least 30 out there whereas last year if you asked me I 
would have guessed 10 max.  I had three, but I traded one away a few months 
ago.  The 8088 co-processors were sold in Europe more so that the US,  
Handic of Sweeden made a spreadsheet for the BX model

The system is under-powered when the 8088 is installed and performance is 
inconsistent.  Check your voltages.

If you can get it to disk, here is MS DOS 1.25 for the CBM-II with 8088

(let me know if it works).
