You mean "SSC" - Specialized Systems Consultants. I did work for them
in the 90s and they started Linux Journal, for which I wrote a few articles
early on.  The main guy there, Phil Hughes, was an interesting person.
After getting rich from LJ he dropped out and moved to Central or South
America.

CSSC is the GNU project's reimplimentation of SCCS, to which, I believe,
Larry contributed.
