and IOtech does make HP-IB cards.

what chipset does the IEEE-488 one use?  Good luck getting docs from
IOtech.  I had some IOtech IEEE-488 <-> SCSI bridges but couldn't get any
docs from them.  The good news though is that many IEEE-488 cards used 1
of only a few chips.  That would be a way of identifying the card for
sure.  NEC 7210 and TMS 9914A are 2 common ones.
