DL10 documentation

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... :-)

Yup, that's what it was.

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:

  WE HAVE GONE TO CONSIDERABLE DIFFICULTY AND EXPENSE TO ASSEMBLE A STAFF OF
  SORCERERS, SHAMANS, CONJURERS AND LAWYERS TO VISIT NETTLESOME AND MYSTIFING
  DISCOMFORTS ON ANY NINNY WHO ENDEAVORS TO REPRODUCE OR USE THIS PROGRAM IN
  ANY FORM OR BY ANY MEANS, ELECTRONIC OR OTHERWISE, INCLUDING COMPUTERS AND

KLINIK, according to KLDCP stuff.
