 '''TENEX''' was an early [[operating system]] for the [[PDP-10]] line of computers; it was the ancestor of the later [[Digital Equipment Corporation|DEC]]-supplied operating system for the [[DECSYSTEM-20]], [[TOPS-20]].
-It was written by a small team at [[Bolt, Beranek, and Newman|BBN]] for a [[KA10]] modified to add the hardware for [[virtual memory|paging]] (much as the [[MIT Artificial Intelligence Laboratory|MIT AI Lab]] added hardware to their KA10 for the same purpose). (The lack of a DEC [[mainframe]] with paging at the time was the primary driver for the creation of TENEX.)

(The lack of a DEC [[mainframe]] with virtual memory, at the time, was the primary driver for the creation of TENEX.)
 The [[Berkeley Time-Sharing System]] for the [[SDS 940]] was an important source of concepts for TENEX, along with [[Multics]].
-It was later adapted to run on the paging hardware supplied by DEC with the [[KI10]] (although not as efficiently). There is also a report of one [[KL10]] running TENEX. It was the native operating system for [[Xerox PARC]]'s [[Maxc]] computers, as well as the [[Foonly]] machines.

 ''The 940 OS (mostly written by Peter Deutsch) was based on paging, viewed memory primarily as a cache for drum, had jobs with multiple forks which could optionally share pages, used the topmost fork of the job for the "shell", and had command and filename completion.  Sound familiar?
