ISTR the DTE was a DMA interface, not memory mapping
like the DL10
I don't know either; I could probably work it out from looking at the DTE
documentation, which I'm too lazy/busy to do... :-)
I also seem to recall that MC was designated as a
"1080" which the above
URL says means "Model A, External channels only, tall cabs
Yup, that's what it was.
I remember finding documentation on MC for
"KLDCP" the original DEC
front-end software (suitably defaced) which DEC later replaced with a
modified version of RSX-11
MC, on the other hand, ran KLDCP ('KL Diagnostic Console Program') until the
end. (The sources of DEC KLDCP version 7 are still available from the MC
dumps, if anyone wants them, along with the MIT-modified version.) The console
-11 on MC ran a 'combination' of IOELEV and KLDCP - the two remained pretty
much separate, just cooperated to share the machine:
KLDCP does JSR PC, [to 03000] when it has nothing to do and 10 is
running. IOELEV should INIT if it hasn't already, then go into its main
loop. It should CLC, RTS PC if the 10 goes down; KLDCP will print
appropriate message. To go into temporary KLDCP command mode, SEC, RTS PC.
I get the impression from the IOELEV source that it ran on the -11 connected
to the DL10 first (stand-alone, by itself), and was later adapted to share the
console -11 with KLDCP.
Amusing comment in the KLDCP source:

KLINIK, according to KLDCP stuff.
