An RLOI/RL02 Disk Subsystem consists of one to four RLOI
or RL02 Disk Drives, daisy-chained via an va drive bus
cable to one of three controllers. The controller may be an
RL1I, RLVII or an RL8-A, depending upon the processor.
The RL02 (using an RL02K-DC Cartridge) is the double
density version of the RLOI (which uses an RLOIK-DC
Cartridge). Below is a list of subsystem characteristics.
