Well here are the captures of magicmac running on a Centris 650 (lot smaller than the quadra) the performance is excellent, i don't understand German so all the preferences menus are really hard to get what you are doing.
This centris have 128mb (maxed out) ram scsi drive and onboard video (tops at 800x600 256) 68040@25mhz

Add all the atari st apps that run good here/ games etc. to have a functional fast atari st out of any old mac.
Also i tried the pc vercion and runs on windows 7 32bit hell fast on a core i3, the diestro could by run on any vercion, mac ppc,mac 68,pc. I prefer the 68k vercion is the most "real" one.
