History

RL Monitor System, as it was initially called, was developed on a 4K (12-bit) PDP-8 with "a Teletype that had a paper tape reader and punch and .. a single DECtape."^[3] It was a disk oriented system, faster than its predecessor, the PDP-8 4K Disk Monitor System, with tricks to make it run quickly on DECtape based systems.

Still named RL, it was submitted to DECUS in 1970.^[4]

MS/8 was replaced by P?S/8^[5] and COS-310.
