My dad used to write custom accounting software for small businesses to run on the Wang 2200 office minicomputer system. He picked up a Sinclair ZX81 to see if it was something he could use professionally and quickly concluded that it was too primitive, but it was cheap enough that he let me play with it. I sat down with it and the BASIC manual and figured out how to write a keyboard controlled animation of a cat. I was 9 and obsessed by cats. I think my dad was a bit taken aback that I'd managed it, but the ZX81 was basically mine from then on and computers were my new obsession. That's a personal core memory right there!
