I am curious, I have not read the historical documents.
Can you please post a link?

As for Y3K for RT-11, since the date is presently managed
up to 2099 as of V05.07 of RT-11, dates starting in 2100
become the next problem.  And since adding support only
for an additional 128 years seems like a complete waste of
time, then 3000 CE was chosen as the next minimum step.
In practice, at least an additional 4000 years would probably
be added, more than enough to handle dates until the rules
for the CE (Commercial Events, Common Era, Christian Era
or Gregorian - all are identical and have a 400 year cycle)
Calendar requires a rule change to handle years which are
less than the current 365.2418 days.

So Y3K is really just Y2.1K if that makes a difference.
