@kdfrawg Yep. We printed out the temperatures of all the thermocouples in the reactor (on that green stripy paper), carried it back to the office, typed all the numbers into our computer, calculated the appropriate alarm settings using a language designed for handling personnel records, then printed the output to punched tape, carried it back down to the control room and fed it into the computer that ran the alarm system.
