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?
