I'm having severe problems trying to connect a Hitachi DK511-8
winchester disk one of our computers, a Sequent Balance 8000. When I
try to connect it to the computer via the internal Adaptec ACB5500
controller, I can't even format it. I get partial success using an
Adaptec ACD4000 (that I think isn't really SCSI, but rather SASI), but
when I try to run the "seek" test program I only get a _lot_ of
"check sense" errors. (And when I try to make a file system on the disk,
the SCSI bus dies...). I *think* that the disk has a ST-412 interface
but I'm not really sure.

And no - I don't have _any_ documentation at all about these disk
controllers. If anyone has some information about these that could
be emailed to me I'd be very grateful. I especially could use some
information about the set of eight jumpers (I have figured out how
to set the SCSI ID using three of these, but I haven't got the faintest
idea of what the rest of them are. When I tried to set the ones on the
ACB4000 controller the same way that they are on the ACB5500, the
controller refused to work.
