One of my co-workers, Serge Vakulenko, just gave me a small gift --
a 1 x 2 inch computer chip that runs a version of BSD Unix, complete
with compilers and editors. It's powered by the USB port and you
connect with it at 115200 baud (10,000 x faster than a model 33
TTY!). It has a surprisingly big file system and 128K of RAM, half
of which is given to the system. There are lots of BSD games,
including a game of Go Fish that I wrote for my son over 50 years
ago. It was interesting to me to look at that early C code. I
was surprised at the nonzero number of gotos (5).
The source is on
https://github.com/RetroBSD/retrobsd/blob/master/src/games/fish.c if
you are interested...
For extra credit, see if you can find the bug that Serge found in this
50-year-old code, and figure out how the program seems to work OK
anyway (Hint: type mismatch). There clearly was a good reason to
invent Lint and declarations and header files...
Steve
PS: if you'd like a look at the chip, google PIC32-RETROBSD. The CPU
is a MIPS microcontroller.

You're probably right but it wouldn't have mattered. SunOS was very
popular
and had a good VM system with a working mmap. Once it became official
AT&T source everyone would have moved to it over time.
Sort of obvious in retrospect. Nobody, that I know of, considered it
at
the time. I proposed open sourcing it.
