I thought I'd be misunderstood. I meant the purposes the computer systems were 
put to. In one case it was the closed-loop control of a nuclear power reactor 
(AGR); in the other the analysis and control of the national power grid. And 
the lights stayed on!

Yes, of course. Them was the days - when we was young. Miles of 8-hole tape 
flying around the room. Entering boot code manually on key-switches. Two-day 
course in maintenance of ASR-33 and KSR-35. Back injury from manhandling a 
power supply into position. Aye...hmm...
