To be honest, there are no really playable 68k versions of Quake out there to be found. BlitzQuake and the original ClickBoom Quake of course works, and in really low resolutions you COULD play through the game if you are sadistic...
Oh I dunno...I can run Quake I for 68k through WinUAE at 1024x768 and still get about 30fps. :-D
(But SysInfo thinks I've got a 14 ghz 040 :-D )
