Plug&Play drivers have put matters into something of a state of confusion ...
rather like breaking things apart and then reassembling them into a different
direction. Bear with us, I think we'll have a better solution than we did
with the old drivers if we can surmount the obstacles.

This actually is the common experience with drivers. They are useful for
quick turnaround projects but when you have to fine-tune performance, it is
useful to turn off the autopilot and take over the controls.

2 points that may be of help
1. I notice in the HP catalogue for 1996, there is a 'HP Instrument
Driver' graphic symbol alongside the HP70820A so I'm sure there will
be a driver for that somewhere in the HP collective conciousness. No
such symbols present alongside the HP83480. The others not listed yet.
2. In my limited experience of VEE, I've found it convenient to have
the driver available for the equipment in the early stages but later
on, speed and size considerations have pressed me in to creating
libraries of direct I/O userfunctions. Even using 'Component I/O'
sections of the instrument drivers has it's problems. In my experience
of driving 25 different pieces of equipment, direct I/O has always
turned out to be the final and best option.
Hope this helps, or, at best, doesn't hinder.
