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.
