[TUHS] List of earliest UNIX licensees?

Thu Feb 19 04:17:17 AEST 2026

Very fun, this got me to look through my files, and I found my V6 license dated Feb 1980.  There was also one dated March 1977, but I'm not sure we executed it.  Both were licensed to the same CPU.  The 1977 agreement listed UNIX v6, and the 1980 agreement listed Mini-UNIX v6.  Also found the V7 license and several BSD ones.
