Come on guys, there has to be a bunch more TPU'ers that have some awesome old hardware laying around!!!!
To update the old stuff LiNKiN sent me, I put together a Windows 98SE system
Stuck on Doom, Doom2, Hexen, Heretic, Quake, and Quake 2
Man, Saturday night I ended up playing Doom 2, and Quake 2 for about 3 hours! Of course the graphics were not very good compared to today's standards, but what a hoot it was to visit some awesome old shoot em up games
