There is just about only one reference online:
The messages transmitted through the ether (or CAIOS) net consist of
a packet followed by a three-word trailer
The reason this stuff is in a trailer rather than a leader is that
the caiosnet hardware actually transmits the packet backwards.
This protocol is intended mainly for communication between the
plasma physics pdp11 in bldg. 38 and a pdp11 in 545, until the
caiosnet gets extended that far (or a longer-distance, lower-speed
caiosnet is extended to various machines off in that direction.)
The ITS file SYSTEM; ITSDEV 974 mentions it:
SUBTTL INTERFACE (?) TO DM PDP11 ON NTY (REALLY WANT A CAIOS)
Something called the "KANSAS dump" has a lot of Lisp Machine files.
One of which says
The initial phase of the LISP Machine Project, that of constructing
a prototype operational system, is rapidly nearing completion.
Current plans call for a complete skeletal system to exist by the
end of 1976.
The CAIOS net (or MACNET or ETHERNET as you prefer) is making slow
but fairly steady progress. Recently, the cable has been ordered
and is in house, and connectors have been decided upon (always a
sticky issue). Breadboard cable drivers and receivers have been
constructed and the prototype interface board made operational. We
expect initial CAOIS net operation to occur by March 1977.
