We have added a new system to the Unix Archive: KSOS

https://www.tuhs.org/Archive/Distributions/Other/KSOS/

KSOS was the U.S. Department of Defense (DoD) Kernelized Secure Operating
System (KSOS, formerly called Secure UNIX). KSOS is intended to provide
a provably secure operating system for larger minicomputers.

Thanks to Tom Perrine who had the tarball and sent it to John O Goyo,
to John O Goyo who sent it in to TUHS and to Thalia Archibald who
curated it and put it into the Unix Archive.

Cheers, Warren
