In 1968 or 1969, I saw an Evans & Sutherland graphics input computer, complete with light pen, at MIT. Along one wall was industrial shelving. Students slept on the shelving, concentration camp style, to get a session on the computers in the room. It was very inspiring; I had already had two Fortran 4 classes at my high school, 1966-67, which had its own IBM 1130 system as well as an Olivetti Programma. But it was not more interesting than Physics.
