[TUHS] Chaosnet in v8

[John Floren via TUHS]

I've been doing some research on Lisp machines and came across an
interesting tidbit: there was Chaosnet support in Unix v8, e.g.
https://www.tuhs.org/cgi-bin/utree.pl?file=V8/usr/sys/chunix/chaos.c

Does anyone remember why that went in? My first guess would be for
interoperability with the Symbolics users at Bell Labs (see Bromley's
"Lisp Lore", 1986), but that's just speculation.

Didn't BSD have Chaosnet support? It wouldn't suprise me to learn that
it was just left over from when Research imported 4.1 BSD.

Dan Cross's note on the providence of these files:

So allegedly straight from Murray Hill.

If it helps trace this, many of the Chaos-related files contain copyrights regarding Nirvonics, Inc. and with authorship attributed to Kurt Gollhardt.

These copyright notices are in extant V8 and V10 sources on the archive (and some backed up headers in some of the V9 artifacts.)

I can't find a whole lot on Nirvonics otherwise, but looks like Kurt was also involved in another UNIX-based experiment regarding "Headturn" studying language capabilities in infants: https://open.library.ubc.ca/media/stream/pdf/831/1.0051436/1
