I'm afraid I have none of those cards at home. Some may have been sold to 
Jan. I can ask him unless he already reads the list. If I find more I can 
pick them up. As far as I remember those cards were rather sparsely 
populated, possibly something for software debugging purposes or used as 
internal hardware dongles for certain commercial software.

By the way, when did Commodore manufacture their first IBM PC clone? As far 
as I understand, the B-series date back to 1983/84. Bo Zimmerman dates his 
PC10 and Colt back to 1984, so the 8088 expansion card must've been 
developed almost simultaneously as the PC line, although probably by two 
different teams and perhaps different development facilities.

In retrospect, it would have been even more cool if Commodore had built PC 
clones with some additional PET daughter board instead of developing a 
replacement to the PET line that would be somewhat IBM PC compatible through 
an add-on. Of course for some users, the B-series outclassed both IBM PC and 
Apple II - see the audience questions at the end of the panel discussion 
last year featuring Jack Tramiel et. al. :-D
