i remember seeing "Chocks" (a flight sim) on the Archimedes at school when i was about seven. It was the most amazing thing i'd ever seen. There was only one Archimedes at school and everyone crowded around it, but there was a load of BBC Micros, so I sat down and started (very slowly) typing in pages and pages of printed out basic programs to see what they did. I'd probably never have become a programmer without that.
