First "computer" I ever programmed was myself, writing up D&D-like adventures for my brother and me to play in, complete with triggers, i/o, subroutines, calls to random number generators, etc.

First electronic "computer" I ever programmed was a programmable calculator (Texas Instruments). You could save something like 40 keystrokes, then replay them. Good for crunching lab data.

First real computer I ever programmed: some mainframe, used punch cards, in Fortran.

First "portable" computer I ever programmed: a PDP-11, you programmed it in assembly using switches, and the answers were delivered in octal using LEDs. That was old even then, but it sure did teach me how computers actually worked.

First computer I actually owned: 66 MHz 486 clone. I'm too cheap to be a trend-setter.

And yes, I too had Pong. Actually, Super Pong!
