I briefly had it running on MIT-AI (the KS, not the KA)

but the CRAM died and we haven't had the cycles available to do something
about that. It's on deck for next year.
I heard (from Don Lewine) that the flakiness of the 93L415 SRAMs led to
the KS's only patent. Even supposedly working CRAM boards get parity errors
often enough that it's worth having the front end stop everything to reload
the CRAM from disk, and maybe the system will live through it.
(Yes, MIT-AI. We purchased it from CZ, who rescued it
from the AILab skip,
then from the Symbolics skip, then eventually sold it on eBay when he had
to. It still has the MIT de-acquisition sticker on the front panel. It's
next to the Toad-1 in the computer room.)
Wicked cool! Guess that machine has 11' lives.
