We have been evaluating a Tandy 4000 unit for the last couple of
weeks and over all, have been very pleased with the unit. It has been
running SCO Xenix 386 without problems 24 hours / day. When we obtained
the unit, we were told that it was fully AT compatible with the exception
of the CPU, speed and of course memory. The point being that we should be
able to use ANY AT/PC card in the bus without problems.
However, today we have just received an Everex EVGA card that
provides 640 X 400 X 256 colours and when placed into the Tandy bus,
prevents the unit from booting; we don't even get failure bells on the
power-up test. So what is this card doing that makes it incompatible
with the Tandy? Is it overlapping the memory space in some fashion;
is the on board EVGA ROM somehow interferring with normal operation?
This card has been tested and does work on a IBM-AT without problems.
If the Tandy is not compatible with this card what other cards
will we have trouble with? I would like to keep this system as it
has proven its reliability, but at this point, it has failed the
AT compatibility test. Any comments or suggestion would certainly be
appreciated.
