My started on my mates apple something..., had an external tape cassette drive, and used to play things like lemmings or prince of persia on it.
I vaguely remember having to type "chain" and stuff at a command prompt.
Then I got my first every computery console. Binatone something... played pong, tennis (pong with a different name, and scoring system), squash (both paddles on one side), badminton (slower version of tennis), and various other pong like games
Then upgraded to a console I cant remember the name of but it had basic colour, with plastic inserts that would slide over 9 button control pads to give you different key combinations to play games like frogger, or space invaders. Something like Maxivision? or multivision??
WOOT!!! FOUND A PICCIE of it!
Then got myself a NES
and it kicked ass!!! remember coming home the day my parents bought it, found them in my room having played super mario brothers for hours and hours while I was around my mates for the day (was meant to be a surprise for me).
