Then that's another diff between the SS5 and Axil-255.  No SCA here, just two
50-pin IDC. Yeah, backplane termination is what I remember reading but that
didn't give me a clue that it was SCA.

I wonder if the Axil 255 is like that.  I'm still getting occasional SCSI
errors after trying a few different things but have quite a few options yet
to try.  (Ignore me, just learning SCSI as I go.) Rave Computers wasn't able
to help this time--said they had thrown out their (Axil ???) manual since the
last time I emailed them.  <groan>  I guess that's okay, it wasn't an Axil
255 manual anyway, but still, it had better clues than the SS manuals.
