I've seen it before, my favorite thing (or two) that he says in there, that I can relate to, is how he likes working on them and sees them as marvelous machines more than he sees them as games to play. I feel like that too, I don't play them as much as I like making them work again.
Also he said how it's funny to him how they still work when you turn them on, and they have 'no concept of time' . that's exactly how I feel too, that's hilarious to me! I've got a space invaders I'm sitting here looking at right now that's doing it's thing, works perfect and it's what, 32 now?
