1Up,
I not only remeber punch cards, but I actually had to work with them 18 years ago. I've also seen paper punch tapes in use.
Let's see, in chronological order I had:
Sears Telegames Pong machine.
Commodore PET computer (All in one unit, Keyboard, cassette player, b&w monitor, no sound)
Magnavox Oddyssey 2 game system with Voice! (I still have it and it still works)
Commodore Vic-20 (Many programs entered from magazines, I even wrote two games myself)
Commodore 128
Commodore Amiga 2000
Sega Genesis (I still have this one too)
Packard Bell 100 mhz pentium PC (Later upgraded to 200 mhz)
Hewlett Packard 233 mhz pentium (My current MAME PC)
E-Machines 1.8 ghz PC
