I don't think they were SCSI!

since these are nasa mainframe tapes, let's hope that they got all the
data read before they
scrapped the above hardware. I also found numerous references to there
being 3490 and
probably 3480 compatable drives on this same set of subsystems.
also
processor.com lists datarefelects computers,
http://www.datareflects.com, as having
refurbed units, they may respond to a query about the units.
If you could post links to the actual cables or interface connecctors,
that might help.
They might be scsi, but would be differential if so, because single
ended was not
allowable outside cabinets. The pertec would probably be 2 50 pin
connectors, but
there was never a really official cable, as the recent overland data
discussion indicates,
and they made up their own.
There was a storage tek drive to controller interface, and they might be
oem drives
from storage tek. That interface had three db-37 connectors and three
cables.
if they were following the IBM lead, they would have a pair of cables
into the
controller placed to be routed under the floor. I think one of them
would have
been a channel type able, one power.
