This was one of the more popular research versions to leave Bell Labs.

Unix v6
Logging into a v6 unix system
Type: Multitasking, multiuser
Creator: AT&T/Western Electric
Architecture: PDP-11, Interdata 32b theoretically portable
Current Version: v6
Date Released: 1975


These are the known platforms to run Unix v6


the PDP-11 was the primary platform which Unix v6 was written on. All other v6's can trace themselves back to this version.

Interdata 32b

The Interdata 32b was the first port to a 32 bit platform outside of Bell Labs.

Folk Lore

v6 Unix is perhaps famous because of the "Lions book". John Lions ( bio: http://en.wikipedia.org/wiki/John_Lions ) wrote up an excellent disection of the unix kernel, and taught it in his OS classes. The book became *the* guide to the unix internals, and was photocopied over & over...

v6 is also important, because it was the first non AT&T port of unix, when it was ported to the Interdata 32b.
