We need to exchange data between an AT&T 3b2/[45]00 and some other UNIX systems via cartridge tape. The other systems have QIC 45 or QIC 150 drives. What standard QIC drives does (if any) does the 3b2 support? (And the same question re Sun workstations, if you happen to know).

I have seen some newer 400's with what are referred to as "60 Meg SCSI drives" (the old formatable ones took only 23Meg on a 600 foot tape); whether these are standard or commonly available I don't know. I don't have experience with 500's or 700's but AT&T support types have told me that they too are QIC-24. The only way I ever found to get anything to and from a 3B2/400 was uucp. > (And the same question re Sun workstations, if you happen to know). I have both read and written QIC-24 tapes on Sun 3's; I think the device was /dev/rst0. But for some reason I didn't look into /dev/rst8 etc don't work - or didn't in my case.

All current 3B2/400's come with 60 MB QIC-24 format (SCSI) tapes built it. The older 3B2/400's and the XM (expansion modules) for the 300 and 310 had 23 MB tapes, but only because at the time of their introduction 60 MB tapes were not generally available. The 3B2/500 Pkg. B and the 3B2/700 come with 120 MB SCSI tape units (also QIC-24) and can read the 60 MB tapes from the 400, 500, and 600. ----------------------------------------------------------------------------- Hans Jespersen | AT&T Canada Inc. | PLACE SILLY TEXT BASED PHONE : (416)499-9400 | GRAPHIC DOODAD HERE.

The 120M cartridge tape drive on the 3B2/x00 will read/write
QIC 120, and read QIC 24....I never tried this...just read about it...
