Algorithms fascinated me long before I could hope to ever get my hands on a computer to implement them.
I used to scribble them down and imagined what it would be like if I had a machine that could run them. This dream became reality when some of my mates came into possession of programmable pocket calculators – the world would never be the same again.
Later I got to write programs on a table top calculator that could save the RPN instructions on magnetic cards – what a revolution.
There were FORTRAN on mainframes, complete with paper tape and punch cards, and desktop programming.
