[TUHS] Fwd: [multicians] Dennis Ritchie's 1993 Usenet posting "BTL Leaves Multics"

[Dan Cross]

FYI, Tom Van Vleck just passed this on the Multicians list; DMR's
recollections of the end of Multics at BTL.

I can't resist asking about the nugget buried in here about Ken
writing a small kernel for the 645. Is that in the archives anywhere?

As far as I understand, the code that is available is for the DPS-8M.
I have asked around for older code.  I don't remember exactly, but
possibly 6180 era code might be around, but but unfortunately not 645.

This is, as I understand it, true for Multics. But I think that Dennis
was referring to something that wasn't Multics, or only tangentially
related, done by Ken; this would have definitely preceded the 6180
(Tom's link here:
https://groups.google.com/g/alt.os.multics/c/1iHfrDJkyyE/m/Nhmar1sFRBgJ).

To quote:

This is the thing I'm curious about.
