SOME VAX models could RESTART instead of REBOOT after a power outage, the contents of memory having been preserved in batteries.
I once saw a DEC-20 with magnetic core memory restart after a week without power after a failure on Christmas eve. The console said something like:
%^$^&*!8r9r% %DECSYSTEM-20 NOT RUNNING [Front End reloaded by KL10 processor] .... RSX20 startup stuff .... [SY0 Redirected to DB0]
PWRFAIL - attempting to continue system
%DECSYSTEM-20 NOT RUNNING
BUGCHK PWRRST - Power Restart System succesfully recovered from a Power Failure
[DECSYSTEM-20 Continued]
And all jobs carried on from where they were a week previously. After the core memory was unpraded to MOS memory you only had about 30 seconds to run into the machine room and reset the breakers after a power trip before the very limited battery (probably just a big capacitor...) expired.
