Hi Mark
Yes, I have done that, a lot.
Your board is missing the second port transceiver chip. The early boards =
came=20
in several versions, some fully populated, some not.
The problem I have is many of the old boards didn't silk screen the =
setup data
on the circuit board and of course the instruction sheets are long gone. =
I ended=20
up having to buy new (old) boards just to keep the frustration level =
down.=20
There are several companies that sell the old boards, fully populated =
with the
setup inscribed on the boards. I just bought four for $12 bucks each. =
You may=20
find a better deal on ebay.=20
The irony here is I also bought four more Pentium 90 machines for the =
multi-multi
and they were only $2.50 each..... Supply and demand at work, this =
would be a
good paper for some economics 101 class.
