Here, it is, straight from the announcement letter:


Abstract

The IBM 9427 8mm Tape Cartridge Library offers AS/400 users low cost
automated tape storage of up to
280GB in a very compact space using industry standard 8mm Tape
Cartridges at very low costs per
megabyte of storage. Each 9427 includes one or two 7GB 8mm tape drives.
The 9427 supports two
ten-cartridge magazines for a total of 20 tape cartridges. The 9427
comes in single drive (#0701) or dual
drive (#0702) versions. The dual drive feature is field installable.
Tape cartridge capacity is 7GB and the
instantaneous data transfer rate is 500KBps. Using Improved Data
Recording Capability (IDRC), effective
compressed tape cartridge capacity is up to 14GB, and effective data
transfer rate is up to 1MBps,
depending on the type of data. Total 9427 capacity is up to 280GB with
IDRC active. The 9427 can be
used for save/restore, alternate IPL, program distribution, migration,
data interchange, automatic migration
of data between DASD and tape, and mass storage for data archive. The
9427 8mm tape drives are
capable of reading and writing cartridges written by the 7208 Models
002, 012, 222, 232, and AS/400
internal tape drives. To write cartridges on the 9427 to be read on one
of the above tape drives, it is
necessary to use a cartridge of the correct capacity (2.3GB, 5GB, 7GB).
Full interchange of data is
supported with the internal 7GB 8mm Cartridge Tape Unit feature on the
AS/400 Advanced Series.
