SCSI connectivity

My main problem is with the 2940AU, though the support, or lack thereof, is not
a design problem, but rather an ADAPTEC administrative policy. Their policy is
that once they've got your money, you don't matte any more.

Another comment is below.

2 gig's??? The two '0662's I have right here are both 1 GB. Are there different
models? I've used 'em together with larger drives but they've always claimed to
be 1 GB drives, which is what they claimed when they were new. They are about
the best 3-1/2" SCSI drives I've used, in that there's never a problem and they
always behave just as expected.

If you think an Adaptec ROM update will help with that, i.e. making them 2 GB, I
think you'll be disappointed.
