I've installed several Wangtek 60Meg's in compaq's and Wyse '386s with a great
amount of pain and aggravation.  All these machines run SCO 2.2.3 but I 
don't imagine the problem is a difference between 223 and 231.  The problems
I've found are mainly interrupt related and/or base-address.  The default
interrupts that the WangTek controller comes with are generally undesirable
for a xenix machine.  I'm not sure off-hand what the interrupts were that
I finally ended up with but it was mostly trial and error.  The Wyse'386 was
a particularly nasty one since WangTek themselves said it couldn't be done and
Wyse said they had never heard of anyone installing a WangTek in their machine.
After about 4 hours of mucking around with interrupts and base-addresses the
thing finally worked and has been doing so for about 8 months now.

  In summary, try changing the jumpers on the controller and then "mkdev tape"
with the appropriate changes until it works or you exhaust all possibilities.
