Paul,
The National Instruments cards ARE supported by HPDrive,??? the
program depends on cards based on the NEC uPD7210 and derivatives
which includes most if not all National Instruments ISA and PCI
cards.??? I am using NI ISA cards that are based on NI TNT chip.??? I
have also used used NI PCI cards with HPDrive and HPDir.
Paul.

Hi Glen
???
Thank you for
the heads up OK
The viper baud
and the extra PCB are fully
loaded so as you say there must be 4 meg of Ram on
it
So this can be
made up into an old
computer for playing with later
???
I will have to
sort out another GPIB card
to go into a modern computer for the HP drive
Project ???
As apparently
the National instruments
card is nor supported by the HP drive program
Regards Paul B

The 82321 board itself has at least 512KB of
RAM, plus room to install
another 512KB. Each 512KB is 4 chips, I assume
they must be 256Kx4
chips. The 82305 board is a RAM expansion
board. It has at least 512KB
of RAM, plus room to install another 2.5MB of
RAM. If you have the
82305 expansion board installed then the 82321
board must have 1MB
installed, so then you have at least 1.5MB of
total RAM, and up to 4MB
of total RAM if the 82305 board is fully
populated.
I'm not sure how using a Viper board would
related to the the HPDrive
software. The HPDrive software uses a
non-intelligent GPIB adapter to
emulate an HPIB storage device and is only
compatible with certain
GPIB adapters. You couldn't run the HPDrive
software directly with a
Viper board. I suppose you could set up two
systems, one running HP
BASIC on a Viper board and another system
running HPDrive with a
supported GPIB board and cable the two
together so the Viper board
sees the HPDrive system as an HPIB storage
device. I'm not sure what
the point of that would be though.
