Looking at some VM stuff, I came across this:
http://bitsavers.org/bits/AmericanInformationSystems/

It seems American Information Systems was a short-lived National Semiconductor spinoff that made a 32016 based board that plugged into a PDP-11 QBus:

It ran a version of Unix called Genix that appears to be SysV R2 derived, but with VM code that is neither 4BSD derived, nor SysV R2.4 derived.

The VM code names David I. Bell and Laura Neff as authors.

Anybody recall American Info Systems and/or Genix?
