turers industry-wide felt the pressure as companies discovered that
a string of inexpensive PCs could be networked to do the same
work that had once been the province of the minicomputer.
Meanwhile, Digital’s storage group kept advancing DLT tech-
nology. In 1991, the company introduced the TF86 (later dubbed
the DLT 600), which offered 6GB of storage on the same 1,200'
DLTtape III (known at the time as CompacTape III) cartridge.
This new drive was read/write compatible with the TF85, pre-
serving customer investment in drives and media.
Two years later, the company introduced the TZ87, now known as
the DLT 2000 tape drive. This advanced system offered 10GB of
native capacity on a single CompacTape III cartridge (now known
as DLTtape III), 2MB of read/write data cache memory, and a data
transfer rate of 1.25MB/s. In 1993, Digital also introduced a com-
pact five-cartridge tape loader (now known as the DLT 2500) that
