TOPS-10

TOPS-10
Type:	Multi-tasking, multi-user, virtual memory
Creator:	DEC
Architecture:	PDP-10
This Version:	7.04

TOPS-10 was DEC's operating system for the early PDP-10 computers. It was descended from the 'Monitor' OS used on the PDP-6. It provided both batch processing and time-sharing capabilities.

TOPS-10 allowed programs to be separated into data and object code segments; the latter could be shared by all processes running that program. Once support for virtual memory was added to the hardware (in the KI10), TOPS-10 added support for that.

How to get this running

TOPS-10 can run under emulation in SIMH and KLH10.
