In the early 70's, the beginnings of computerized industrial
process control, using a general purpose scientific mini-computer to
control power plants. Using 12K of core memory, ran two huge
boilers and all the auxillaries. Programming accomplished using a
Teletype ASR-33, stored on paper tape, about 550 feet long. It
took over twenty minutes to load the tape, if it didn't kink or miss-
read. If it did, start over! Ahh, the good old days.
For US-er's, Happy Memorial Day...thanks to all who served!
