Is that biased by the experience of failures that appear when
equipment is powered-on?
Is there anybody here who keeps classic big(-ish) iron running 24x7?
I've been told a story of a burning PDP-11/34 which has somewhat put
me off any notion of leaving my -8s turned on when I'm not within
reach of a killswitch & fire extinguisher. :)
PDP-10 model 2065, 24x7
VAX-11/780-5, 24x7
I've often left the PDP-8/e up over the weekend, running diagnostics. -- Ian
