1980s personal computing explosion

December 1981, I received a Commodore Vic20, my first computer :-)

Spent hours typing in BASIC code, line-by-line; and being completely amazed that the program worked! Usually a game.
Upgraded to a cassette drive, wahoo!
First game Jelly Monsters. This is very Pac-Man esk. (imho best game ever)

What was your first computing experience and what impact did it have on you?
