My first experience of computers was on the Durham University Mainframe in the late 70s. The machine was actually in Newcastle, which added to the slow response. It was water cooled, so occasionally we got the message: "Sorry, the computer is down. The plumber has been called." . They had just moved from tape readers to card readers programming in Fortran IV as previously discussed. In my third year I was allowed to use one of the new "Green screen" consoles - there was a waiting list and sometimes it was the middle of the night before I got on. Nothing much has changed - there was an entirely word based adventure game on there - a bit akin to dungeons and dragons - and that soon occupied too much of my time!
About then the first PCs arrived - a Commodore PET with a whole 1k memory, programmed in Basic and with a cassette tape to store your efforts on. All the professors were very snooty about it and insisted it would never catch on. I was as pleased as punch when I created a worm chasing its tail game - you can still find them on older mobile phones.
Ahhhh! Nostalgia ain't what it used to be...
