==Another Systems Concepts?==

While looking through [[SDS Sigma series]] material on Bitsavers, I found [http://www.bitsavers.org/pdf/sds/sigma/tsd/TSD_Design_Specification_Jul67.pdf this], "TIME SHARING ASSEMBLER AND DEBUG SYSTEM", dated July 31, 1967, and shown as being done by "Systems Concepts". I don't know if it's the same Systems Concepts, or another organization of the same name.

That one's address is given as:
SUITE 300 FIRST FEDERAL BLDG.
401 WILSHIRE BOULEVARD
SANTA MONICA, CALIFORNIA

The address given in the SA10 Users Manual (March 1, 1975) is given as:
520 THIRD STREET
SAN FRANCISCO, CALIFORNIA
but that's 8 years later, and they might well have moved - or the Santa Monica one might have folded, and another organization of the same name might have been started.

A Web search doesn't show up much for 'Systems Concepts Santa Monica', except that Larry Tesler [https://www.nomodes.com/larry-tesler-consulting/1962-1980 worked there]! [[User:Jnc|Jnc]] ([[User talk:Jnc|talk]]) 18:01, 13 August 2025 (CEST)

The Nelson-Levitt company was in operation at least from 1969, see https://dspace.mit.edu/bitstream/handle/1721.1/6174/AIM-172.pdf We could try to get hold of Stu Nelson, Peter Samson, or Fred Wright.

		+	::: Information from Fred Wright is that Systems Concepts was founded in Cambridge in 1969 and soon there after moved to San Fransisco. But possibly there was an (informal) entity before that, and possibly they may have shared a Santa Monica office with III.
