MS/8 or The RL Monitor System is a discontinued computer operating system developed for the Digital Equipment Corporation PDP-8 in 1966 by Richard F. Lary.[1][2]
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.
