I don't know anything about this particular application, but one thing to
keep in mind for anyone else integrating other systems with HP 9000
Series 300 machines is the HP VMEbus interface.  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.
