This is a very old source file -- AI: SYSENG; MONIT 114 is listed in
MAPS in 1971-04. Development happened on DM; "Scenarios for Using
Arpanet at the International Conference on Computer Communication" has a
1972-09 transcript showing MONIT 192 on DM.
The binary SYS; TS MONIT is listed on AI, MC and ML from 1971 to 1983 in
MAPS, although it doesn't survive in the AI/MC KS10 dumps. A 1981
message to BUG-ITS from ED@MIT-ML suggests it was an old version:

where the default of > would be more appropriate. This fixes, in
particular the incorrect compilation of LIBDOC; TIME KMP8 instead of
LIBDOC; TIME KMP9. Resolves#1091.
The ITS pager parameters was based on the ML configuration, but the
emulator implements the AI pager. Thus one of the ML pager age bits
was treated as an address bit, which of course resulted in an NXM
error.
This is a standalone program using the PDP-6 Microtape device.
The source code has been fixed to assemble with the current version of
MIDAS. Double !s are needed to get the concatenation right. Also,
garbage at the end was removed.
to new DOTIMES and DOLIST macro definitions (in the case of FASLRO, update
to use DO rather than DOLIST since DOLIST no longer (as of latest UMLMAC)
binds a parameter to the loop count. Resolves#1054.
This is assembled with MIDAS, and then translated with IMTRAN to an
ASCII form suitable for uploading to an Imlac terminal. MOUSE is
enabled to ensure the MSW opcode is defined.

- Add packs to SALV.
- Increase NQS in ITS.
- Add new drives to the emulator configuration.
- Mark two more packs in SALV.
- Before booting into the new ITS, use UCOP to copy the MFD to the fresh packs.
It would seem the EBLK above POTUSR matches the BBLK after DRECYC, but
since the first is inside IMXP and the second inside 340P they don't
match if one is enabled and the other itsn't.
