<That's a risky proposition. CompuPro produced some of the best but much o

I have two systems and spares for two more and am using some of them in
other systems, all work. From some 10 systems I aquired and parted out to
several here. Those 10 systems ran a small company and I know their history
and the original owner would also argue they were solid. Generally the
later IEE696 complient boards are very good and my experience over 20 years
says they were one of the better vendors. HOWEVER::: The 696 complient
boards often did not work in systems that were way off the spec or were
pre696. My ALTAIR and the NS* systems are amoung them for the most part.
the NS* mis uses a few lines so the timings are off and a few liknes are
ground that would be otherwise assigned. Standard S100 problem till about
'83-84ish.
The most interesting and scarce bord they did was the MPX-1 an IO
processing slave. I'm running one with a DISK-1 and DISK-3 in a z80
system to offload the IO (most of the bios) and it's really a sweet deal.
