Unix history goes back to 1969 and the famous "little-used PDP-7 in a
corner" on which Ken Thompson, Dennis Ritchie (the R in K&R) and others
started work on what was to become Unix. The name "Unix" was intended as a
pun on Multics (and was written "Unics" at first - UNiplexed Information
and Computing System).

And then goes on to list signifcant versions, including something called
V1 that was written on an PDP-11 in '71.  So, perhaps V0 was written in
'69 on a PDP-7? (DMR was a zero-based kinda guy, after all.)
