Thank you. Yes, I have not updated these notes since then.

Two of these three were in Sandy Fraser’s archives:



The middle one is I fear lost - unless a paper copy of the proceedings is still lurking in some university library. I think it will be mostly about the “CMC” switch control software, which is somewhat described in the Luderer paper as well. As far as I can tell, there is no surviving Unix code that was designed for the CMC version of Datakit (unless someone is sitting on a V7 tape with the Datakit drivers still included).

Out of interest, would you know if the switch-host interface for Datakit in the days of Plan9 worked more or less the same as in 8th Edition? Or had it much evolved by then?
