Floppy disk drive
The floppy disk drive in the controller provides an alternative
input for loading operating system software, user files, and fonts,
to the system disk. It can also be used for backing up system-
disk-resident user files and fonts. A service representative may
also use it for diagnostics. It is not an input source for print
jobs.
The disk drive uses 5.25-inch double-sided, dual-density disks,
and 5.25-inch high density floppy disks. The floppy disk has a
total of 1403 available sectors; sector configuration is 78
cylinders, 2 tracks per cylinder, 18 sectors per cylinder, and 512
bytes per sector.
1/4 inch cartridge tape drive
The 1/4 inch cartridge (QIC) tape drive is also mounted within
the system controller cabinet. This unit provides an alternative
source for loading and backing up user files and loading or
unloading fonts to the system disks.
The capacity of the 1/4-inch cartridge tape drive is either 320 MB
or 525 MB, depending on the choice of DC6320 or DC6525 tape
cartridges. Both tapes are 1/4-inch cartridge ANSI compatible,
and they can be used interchangeably without hardware or
software reconfiguration.
