Rubywand,

I am never one to argue with you, but actually a ROM03 machine is *slightly* 
faster when running GS/OS apps. The reason for this is that more of the GS 
toolbox is rom-resident. Ram on the GS operates at ~2.5Mhz whereas the ROM 
operates at ~2.8Mhz (due to the RAM refresh cycle). Additional toolboxes are 
loaded in RAM on a Rom01, so the toolbox routines are slightly slower.
