Disk system up. EDIT2 [?] worse than usual.
C command followed, for example, by 5C type 5C instead
of going into the proper mode. nK give xNLNx or garbage
and will not bill. Old system loaded

March 19, 1968

Yesterday the system died in a mysterious
way: The first thing that was noted was that the
DEC TAPES would not respond to anyone's command.
(Pierre had been using the MAG TAPE, but it was not
running when the DEC TAPES failed to respond.) Shortly
after, the system restarted itself without the
help of any bystanders! The system did not really
restart, however. A 140 restart and a 143 restart was
tried, but to no avail. We then loaded 16K DEC DUMP
and ran BLT for 5 minutes without any errors. We
then ran T.S. Main for 5 minutes, and again had no errors.
We also ran Instruction Test Part 3 (which is not included
in T.S. Main) for few minutes and got no
errors. We then loaded System 2.08 and everything
operated normally. The reason that the system died
is still a mystery.
