The reason that the world ends in 2027 for MPE is that only 7 bits were
allocated for the year number (0 to 127), and the start year was defined to be
1900.
January 1, 2028 is thus the drop-dead date for the HP3000 (sort of). I
presume that the counter will simply roll over at that time and we'll all return to
1900 again, in our own special version of a time machine.
