Had the same, and the Amiga afterwards. On the 64 we had a booklet noting load times of all the games. Took my first steps in programming too, my advanced studies were in pure math, chemistry and computing, though I never finished the courses.

Not got any now, but miss many of the old games, simpler and more pure fun than those made now. Not quite there, but dosbox is definitely worthwhile now.
