ThePDP-8 Disk Monitor is a discontinuedoperating system released byDigital Equipment Corporation for theirPDP-8 line of mini-computers. The minimum hardware requirements consisted of aASR 33teletype,[1] 3 cycle data break (an option on the PDP-8/S model), and a mass storage option of a DF32 disk sub-system or a TC01DECtape unit, with later releases the additional option of using a RF08 disk drive. The distribution media was onpaper tape, a common means of data storage for computers of that era. The included user programs consisted mainly of modified versions of the paper tape software library distributed by DEC for their PDP-8 family of small computers, much of this was exported to theTSS-8 andMS/8 operating systems.
A modified version of this monitor was used on "8K or larger PDP 8/E" systems, with one of its claimed benefits being that it made better use of additional DECtape drives than OS/8.[2]
