If you could just have and own two PC's to play all your games on say from the late 80's until 2001. What ones would you have and how would you config them.

I say for games from the mid 80's to like 1991, a 386 or a 486 33Mhz. For the rest a PIII say like 800 - 1000Mhz. And slow down programs for both to fill in the gaps.
