So no-one started out on a PC or Apple II? I suppose the monochrome graphics and speaker that goes "beep" was not something to impress your friends/family with.
I started out on the Vic-20 and I liked typing in and tinkering with the Basic games. I got my first go at text adventure, there was a haunted house you had to go into in the game.
My aunty&uncle, had an old PC with trackball you could play stick figure games on and various brainteaser games.
