Well, not really. Here ya go:
http://ftp.gcu-squad.org/tuhs/PDP-11/Distributions/research/Henry_Spencer_v7/
The original Unix v7 sources for the PDP11. Including 'sh' and 'cc'.
There's also a binary distribution floating around on the net,
and a PDP11 emulator. I've booted Unix v7 (from 1979!) and recompiled
some utilities, talk about retro computing!
Ah, at the same site. See
http://ftp.gcu-squad.org/tuhs/PDP-11/Emulators/Supnik_2.3/
Anybody want to do a Debian/V7 ? ;)
Ofcourse, all this stuff predates posix by at least a decade.
Mike.
