That's great that SBS has them available on their website now. Back in
97/98, Bit3 themselves were a right pain to deal with and wanted much money
for various software, manuals, etc. This was maybe 'cuz the 973 was new
product, but still, don't abuse your customers!
Anyway, during development, we ran the application in a mode that did not
require the windoze PC to be lashed-up to the VMEbus equipment. However,
the Bit 3 drivers HAD to be installed for the homespun hardware emulator to
work. This is great in that I can download and install the Bit3 drivers and
once again perhaps play with this application, an old friend :-) Seems the
compiled application was around 1 meg in size, large for those days with
minimal GUI requirements.

Well, I'll rummage around in the directory where I have the project stored
an email them to you.
Are you indicating that SBS/Bit3 has updated drivers for windoze xp?

Both ends of the VMEbus need to be terminated, so slot #0 having
terminators is fine. Look at the last slot at the other end and see if
there are terms there. Also, and this is where my memory fails me, there
*may* have been provisions to terminate the bus on the SBS VME board. The
manual should discuss that.
>5) This is a VERO chassis (if that has any relevance).
I believe VERO was a good VMEbus chassis/motherboard mfgr., so it should be
a good, quiet design. Never had personal hands-on experience with VERO though.
Now, with all this said, I'm very interested in getting a 973 board set,
and cable, for myself so that I may experiment with lashing up PCs and to
of my VMEbus systems! Anybody have any PCI/VME Bit3 interface card sets
