I fear I may be a fair bit older yet. I started programming in BASIC on an old Commodore 64, moved up to an 8088 with GW-BASIC (not counting the Unisys Icons at school), before I got my own computer some years after that - a nice 286 (Q-BASIC) (which also caught fire, interestingly enough: the plastic on the speaker wires starting smoking one day for no reason I could fathom). To really date myself, my high school still had old PET computers in a storage closet (they weren't actively used anymore but they were there and still functional).
And I will be keeping an eye open for Third tidbits you decide to let slip.
(Edit: Apparently I'm a sucker for punishment but to add to the above, when I was still a kid, I played Centipede with my neighbour on their Commodore VIC20.)
