In the 1960s I worked as a researcher analysing inpatient statistics. I was told when I started that there were two computers I could usd. The university had a computer and the regional hospital board also had a computer. I used the hospital board computer, writing my programs in Fortran, having them transferred to punched cards, then inputing them usually at four o'clock in the morning.
I also helped to teach statistics to medical students. Lesson one was how to use the Facit mechanical calculatot.
I've got another 'keen'... Ouch!
