Hello there, 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 have a design ready now for this interface, but before we actually build it we would like to know if someone out there already has build an interface using the GPIO bus. If so, what are your experiences with the GPIO bus, are there thinghs to take especially care of, do you have some advice for us ? For a second interface we want to use the HPIB. One of our students is working on it now. We also would like to know of somebody already has some experience with HPIB and has some advice for us. Thanks in advance. -- | Camiel Severijns | | Dept. of Physics, Eindhoven University of Technology | | Den Dolech 2, POBox 513, 5600 MB, Eindhoven, The Netherlands | | UUCP: hp4nl!eutrc3!eutnv1!camiel OR: hp4nl!eutrc3!tnvscs |

If I can quote from the HP 9000 Series 300 Hardware Technical Data: The VMEbus Interface provides bi-directional data transfer capabilities between the Series 300 and the VMEbus (IEEE P1014), permitting configurations of both HP-IB and VME systems. The package consists of the HP 98646A VMEbus Interface hardware and the HP 98385A/R VMEbus Driver software. ... The VME master module fits into any standard double height [6U I take it] VMEbus Rack. ... The 98646A provides 24-bit addressing and either 8- or 16-bit data transfers. Data transfer rate is about 950Kbytes/s using HP-UX. I don't work for HP. I haven't even used this particular product. I just looked at it in the catalog recently as a possible solution to one of my problems. Rick Low MEL Defence Systems, Ottawa, Canada +1 613 836 6860 mitel!melair!low@uunet.UU.NET

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.
