Close encounters of the CADR kind

[...] 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. http://www.unlambda.com/download/mit/kansas-orig.tar.gz
