Dot Matrix printers were awesome. I made about $20 a day making fake IDs for people in high school with one of those and a small laminating machine.
My first video game... Well, I beat the original D&D on intermediate mode (Intellivision) when I was about 4 or 5. Never played it on hard after that, the dragon scared the crap outta me. I remember playing Astroblast some time before that... or rather, letting my dad play up to 99 lives or something and then letting me kill them all :P
Edit: Wait a sec, there was no easy or intermediate or hard... There were different coloured mountains. You could get the boat in the blue mountain (easy) or the axe in the red one (harder)... Bah, I was still frightened by the dragon.
