While we are reminiscing, while at University I started to play around with the university computer* as I had some data I wanted to analyse I formatted an array in my programme and took the punch cards to the data room to have them input in to the array. The person at the desk just laughed, I had formatted the array 512 by 1024. This was hundreds of times bigger then the whole core memory of the computer. Yes magnetic beads on wire type memory.
An' you try tellin' t' kids of today that, they won't believe you.
*Yes there was one for the university IBM370 if I remember right. Electrical engineering had their own PDP-11 but for post grads only.
