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-

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-
