1983, 8th grade. I was in wood-shop class and my teacher asked a friend and me if we'd rather be in "computer shop" (I think we were acting up and he was sick of us). First program was on a Commodore PET, drawing on the screen via POKEs to the video area in memory.

Got hooked and for X-mas a couple of months later, my mom got me a TRS-80 color computer.
