Varying things from not loading tapes to SCSI I/O errors. The interfaces are
8 bit SCSI, 50 pin centronics. The one we picked up this morning was showing
I/O errors when powered by SUSE Linux 8.1 with either an Adaptec 2940 or
39160, one last week had severe smoke damage on the servo pre-amp board but
no matching collateral damage on the board it's fastened to! The week before
we had one with the analogue board not giving the pre-req 3V on each of the
channels.
Problem is, we've only got half a service manual with additions of various
bits of paper over the years for running diags/calibration etc but with no
explanation as to why things are done the way they are, just button presses.
I can plug them into pretty much anything from pc to Mac to SUN to VAX to
Alpha.
Cheers :)

What's the symptom and what's the interface...
Pertec?
What are they hooked up to? I seem to remember these on Vaxes back in the
old days and they would run parts of the DEC diags and the OS was a good
test.

Folks,
Does anyone here have good troubleshooting tips and/or spare parts for
these heavyweight beasties? We seem to be having a bad run with a handful
of them at the moment and we're running out of ideas apart from what we
already have in the half of a service manual we've got :o)
TIA!
