Smart ladies
Back in the 70's all the computer operators were young women. There was no IT support, if they couldn't fix it they would fly someone in from the USA to the computer with only one job and had its own room and a/c.
A couple of years later the HP45 appeared and was so popular and save you so much time we used to send someone over to Singapore to buy some at least once a year. You could only ever find one or two in the UK and we wanted at least six at a time, and they were cheaper. I still have mine and it is still working!
