After talking with the folks I bought the recent documents from, they let me know they are
also selling a piece of hardware:

After the link is an auction for an Instrumentation Laboratory Pixel 100/AP. A small
booklet included with the many documents I received indicates as of 1982 the Pixel 100/AP
ran a System III derivative. The booklet goes on to present a summary of user commands
and options. Despite the System III basis, included among these are the C shell and
ex/vi.
I have no room for hardware or honestly at that price point it'd be worth the
preservation effort. Hopefully it finds a good home, it includes an almost complete
documentation set save for the small booklet I've got (which could be separate promo
material for all I know)
In any case, there were a few letters amongst the documents suggesting the original owner
was involved in the production of this system, particularly in the area of OS details. If
I find any noteworthy information I'll pass it along.

P.S. If anyone knows of a preservation effort accepting new machines I can pass this
along.
