Tape Module {TM) (non-SCSI)
The AT&T tape module (TM) offers a less expensive alternative for those customers who do
not need the amount of data storage provided by the AT&T XM. The tape module consists of
a cabinet (5.04 x 7.85 x 15.38 inches) containing the same cartridge
tape
drive used in the XM
along with an independently controlled power supply. See Figure 3-2 for an illustration of the
AT&T TM.
All TM systems consist of the following subassemblies:
11
power supply
• fan (physically separated from the power supply)
• cartridge tape drive (23MB)
NOTE: The 23 MB tape drive manufactured by W angtek may be used in place of the Cypher
model. The Wangtek model appears identical to the SCSI cartridge tape drives.
