OK, that makes 3 of us that seem to have these machines in one form or
another.  I seem to be the only one with drives on the machine to work
from.... (3 shoeboxes with sun0669 drives, although the scsi bus is only
strong enough to power 4 drives and one tape, unterminated, before the
bus dies).

As I understand it, 1.2.1 and 1.3.3 use the polling scsi drivers, which
work fine.  What was changed in the later drivers that might affect how
a sun4100 cpu works?

The sunhardware faq does not say much about the 4100 cpu, as regards the
scsi.

I will download the latest snap I can find and try that, tonight, and
see what happens.
