Speaking of ancient history, I still remember Apple II's from school. The older models were all green, and I can't recall doing anything on those except banging on the keyboard and trying to crash it. Oh, and adjusting the brightness and contrast, that was fun... when the kid next to me can't figure out why he can't see ----.
They also had newer ones with color screens. I think the educational program on it at the time was called Number Crunchers. If memory serves me correctly, I also played Oregon Trail on those machines. Never made it to Oregon though, curses.
Around the same time, my dad either bought or brought back from the university a Macintosh AIO, with a REAL color screen, a mouse and everything. It was in a complete different league than the jokers at school. I enjoyed Crystal Quest. There were other obscure games too, but none worthy of mention.
