ChaosNET implementations for PDP-10

This is not particularly interesting, but I wanted to record a couple of links to ChaosNET code for the PDP-10. The ChaosNET memo describes an ITS (Incompatible Time-Sharing System) interface, for which the code is somewhere in the ITS sources, and a Lisp Machine implementation, for which code is in the CADR sources and Symbolics code base, but also a TOPS-20/TENEX implementation, a VMS/VAX implementation, and a UNIX implementation. The UNIX implementation was documented by James E. Kulp for Symbolics, and the code seems to have survived. The TOPS-20/TENEX is harder to find, but it looks like BitSavers' Foonly archives have some files. DSK:<FOONEX>CHAOS.MAC;399 DSK:<FOONEX>CHABUG.MAC;8 DSK:<FOONEX>CHAOS0.MAC;3 DSK:<FOONEX>CHATTY.MAC;21 I have no idea whether this is at all related to the implementation the AI MEMO mentions. A Google search turns up some interesting code (might be for the PDP-11 front end, for ITS) from AI:SYSTEM CH10.defs1 ...
