Does this critter work on AIX 1 on PS/2 machines, or on AIX 3 on RS6K
machines like my old 7011?

Does it work on non-ibm hardware like Suns or DEC's or such?

What is the capacity of the drive (150mb?)

Thanks

Bob

Should tell you all you'll need to know.

A 7207-001 is a 1/4-in. streaming SCSI tape drive.  When attached to an
AIX system, it can read/write QIC-120 format (like a 3M DC600 cartridge)
and QIC-150 format (like a 3M DC6150 cartridge) tapes.  It can also read
QIC-24 (3M DC300 ??) tapes.  I don't know how you would send it the
command to switch write formats ("densities") on a non-AIX system; on AIX
it's done via the "density_set_x" attributes of the device driver.  The
device attaches to the computer with a plain old-fashioned SCSI interface.
It is NOT internally terminated; it is meant to be used with an I.B.M.
SCSI cable, on which the SCSI-out connection (where the terminator would
go) is part of the connector block.  Any version of RS/6000 AIX (from 3.1
on based on personal experience) should recognize this drive.

The 7207-001 case has only one scsi port.   If that cable is something
special, then I would need to find a way to terminate it or make a dongle
to terminate.  It looks like it might be just a proximity terminator
block.  That means I could hang the thing on a ribbon cable with the
last device.

Now to find the right scsi cable and see if it works on my 7011.

Thanks for the info.....

IBM has/had special cables whose one end is such a "long" SCSI plug
which has a "standard" (= 50-pole Centronics, with the two security
wires) SCSI socket at its back; you might call it a "piggy-back"
or "tower" plug. In that socket, you can either insert another
SCSI cable (to the next device) or a terminator plug.

This "long" IBM plug is fastened to the case housing the QIC drive
by two screws on the lower side of the plug.
The cable is available (at least) with a 50-pole Centronics or
with a 50-pole high density plug at the other end, there might be
other variants I do not know.
