TECO, TENEX, and TOPS-20 Papers

And assorted memorabilia

The Beginnings of TECO

As published in the IEEE Annals of the History of Computing, Volume 31, Number 4, October-December 2009.  Thanks to Dave Walden, editor of the Anecdotes section of the Annals, for inviting me to jot down this bit of 1960's history.

TENEX Goes On The Air June 15, 1970

Read the TENEX NEWSLETTER of July 16, 1970 which reported the birth of TENEX.


TENEX and TOPS-20 Papers

TENEX, A Paged Time Sharing System for the PDP-10
The first TENEX paper, originally presented at the October, 1971 ACM Symposium on Operating Systems Principles and subsequently published in the "Communications of the ACM", Volume 15, Number 3, March 1972.  At 2013 Symposium, this paper was given the SIGOPS Hall of Fame Award.  This award was instituted in 2005 to recognize the most influential Operating Systems papers that were published at least ten years in the past.
Storage Organization and Management in TENEX
In-depth discussion of virtual memory, including mapped files, in TENEX. Presented at the 1972 FJCC.
Origins and Development of TOPS-20
How TENEX was developed into the DEC TOPS-20 operating system for the KL-10 and subsequent machines for the life of the 36-bit systems. 1989.
A Virtual Memory Distributed File System
The TOPS-20 Cluster File System. 1985; revised 1989. Postscript version.

First Network Email

Two KA-10s at BBN circa 1971.
These are the machines between which the first network email was sent by Ray Tomlinson. For other stories about this event, enter first email tomlinson into google or your favorite search engine.

More 1984 group pictures.  A number of pictures were taken with my camera at the time of the same photo shoot as the two pictures by David Dyer-Bennet above. In fact, ddb himself is seen in a couple of these setting up his shots. These scans are from the original negatives and pretty well capture all the resolution they have.
