Many thanks to those who promptly responded to my request for help with the
Xetec Fast Trak controller/ram expansion.  At 5 am, the system finally began
to work (with the Insider card installed).  There must had been something in
the startup-sequence that made the thing guru.  Much wiggling of the card as
well as breaking the startup sequence yielded a completely usable system.

Now a new frustration has arisen.  I was able to get the card going with
my friends drive (from Xetec) but couldn't get my drive (a 105 m Quantum
from HDI Inc) going.  After much calling around and a lot of tearing my
hair as well as the hardware, I think that the problem may involve the way
that the Xetec attains its power.  Correct me if I'm wrong, but does it get
its supply from pins 24 & 25 from the HD?  Checking the traces as well as
putting a meter to all of the pins makes me suspicious of this.  Testing these
two pins on my drive shows that nothing is supplied here.  Further, checking
the Xetec shows that pins 24 & 25 appear to be a short circuit (or at least
a path of little resistance).  I noted a couple of jumpers on the inside
of the controller.  Is there anyway to get the controller to take power off
the Amy bus rather than the HD?

By the way, when my drive is not connect to the Xetec (it doesn't matter if
the Xetec is turned on or not) my drive will not spin up.  Once it is
disconnected from the Xetec it spins up nicely.

If you have anymore suggestions, I'm all ears.  Right now I am a bit frustrated
with the card, but I hate to give up on it.

Thanks again,

Bob
