re: "We need to interface our HP 9000/330 and 340 workstations running
     HP-UX with a special IO-bus developed at our faculty.  For one of these
     interfaces we want to use HP's GPIO bus."

We (at HP) don't generally think of the the 98622A GPIO card as providing a
"bus".  It is most commonly used as a point-to-point parallel interface,
however, nothing about it necessarily precludes bus-type usage.

In addition to the GPIO, you also have available to you...

  * 98624A or 98625B IEEE-488 (aka HP-IB, which you know about)
  * 98658A SCSI interface
  * 98646A VME adaptor
  * 98630A Breadboard card (implement your unique bus on our card)

The Model 330 (but not 340) can also accept a plug-on 98577A VME card cage,
should your bus already be supported by an existing VME card.
