I think I missed some of this in my youth, going from the Commodore 64 straight to a PC XT clone. Monochrome Hercules graphics, but I still coded my first games in it (using GW Basic). I still wonder about this early era of computers that came after the C64. What's the word for nostalgia about something you didn't actually get to experience back then?
