Has anyone tried an ESDI drive in a Sperry IT?
I'm trying to install a CDC 150meg ESDI and an adaptec ACB2322 controller and 
the controller is giving me an error ("controller error!") when I try to call
the low-level format routine in the controllers ROM.  If you've had similar
problems with ESDI drives or AT compatibles, please *mail* me any info you
might have.  I've talked with the supplier, the controller manufacturer, and
Sperry (Unisys), and got no help.  Incidently, I returned the first controller
for replacement after having the same problem and I'm now on the second one,
so I don't think it's a problem with the controller.  Possibly the IT just
doesn't work with ESDI.  Sperry said it wasn't officially supported, but might
work.

Any help appreciated.
