ITS configuration has the Rubin 10-11 in the 3,,0-3,,777777 range.
The documentation says it's one moby lower.
Two more PDP-11s were attached at some point.
Retrieved from <http://web.onetel.net.uk/~hibou/ITSter.txt>. Earlier
versions are in SV: HIBOU; -- I've given this version 186 because it's
identical to version 185 (dated 2002-03-13) except for a change of name.
This is a change to the API, but existing users are already inconsistent
in how they handle 2-digit years -- some assume it's year % 100 (as the
documentation says), some assume it's year - 1900, and some
string-prepend "19" -- so most have Y2K problems that need fixing.
As it's now reading the date using two UUOs, it needs to be careful to
check that the year hasn't rolled over between the two, as LIBDOC; TIME
does for the day.
I've updated all four implementations of SDATE, but only tested the ITS
version.

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:

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.
