That sounds right.

I don't recall anymore, but I think there was only one -11 attached to the
DL10 (couldn't they support up to 4?)? And yes, the Tridents (along with,
IIRC, some serial lines, and the CHAOSNET) were attached to that -11.

Yup. Although it had been hacked locally. After briefly glancing at the
sources (see the KLDCP; directory, and IOELEV > in SYSTEM;), it was a real
kludge; the IOELEV program ran in _both_ the DL10 -11, and the console -11.
(In the latter case, along with KLDCP!!) There was some stuff attached to the
console -11 too, apparently; a bunch of serial lines on DH11's.

Yes, but I don't think that was on MC. I vaguely recall that it was on a
bunch of drives which were mounted in vertical pairs, which must have been
CalChomps, which I think must have been the original AI? (IIRC, both ML and
DM had DEC RP drives.)
