Lincoln Manual 78: Lincoln Laboratory Multi-Programming Supervisor

Alan Davis (UQV) recently sent me several manuals related to MTS. One of which I had never heard of or seen. It was:

Lincoln Laboratory Multi-Programming Supervisor
Lincoln Manual 78 (ESD-TR-67-14)
by Frank Belvin and Joel M. Winett,
6 January 1967, 255 pages.

The MTS supervisor, UMMPS, was initially developed based upon the MIT Lincoln Laboratory Multi-Programming Supervisor (LLMPS).

The manual was scanned and added to the MTS Archive. And once I knew what to look for I found other copies online at Bitsavers and the Defense Technical Information Center (DTIC).

There is a short conversation about LLMPS in the discussion section of the MTS Archive (this site).

 MTS Workshop Proceedings

Don Boettner recently made his collection of proceedings from the 19 workshops held from 1974 to 1994 available for scanning. So far we've been able to scan the table of contents materials (schedules, list of papers, list of attendees) from all of the workshops. They are available in the "Documents section" of the MTS Archive site (this site). We hope to get the full proceedings scanned as well. Once that is done, the physical paper copies are destined for the U-M's Bentley Historical Library. We would like to thank Don for saving the proceedings and being willing to make them available.
