OS/8 is the primary operating system used on the Digital Equipment Corporation's PDP-8 minicomputer.

PDP-8 operating systems which precede OS/8 include:

R-L Monitor,^[1] also referred to as MS/8.
P?S/8,^[a] requiring only 4K of memory.
PDP-8 4K Disk Monitor System^[2]
PS/8 ("Programming System/8"), requiring 8K. This is what became OS/8 in 1971.

Other/related DEC operating systems are OS/78, OS/278,^[3] and OS/12. The latter is a virtually identical version of OS/8, and runs on Digital's PDP-12 computer.

Digital released OS/8 images for non-commercial purposes^[4] which can be emulated through SIMH.
