Man, I have played with a Power Mac 6100 with DOS-card (Win 3.11) and that was pretty amazing back then. Much later on I got a 2nd hand Power Mac 9600 with the Pentium card running Win95....
And now.. just fire up Parallels or Fusion and load every darn Windows version you want. How times have changed.
EDIT: as we're doing retro Mac - PC stuff: nice one too
