you should be able to run v3.5 on a 68000 though I believe the recommended min. was an 030. I believe later versions had 2 executables for FPU or non FPU but earlier versions required an FPU though from my experience you wouldn't want to attempt to render even the simplest object without an FPU as the FPU literally could make up for hours worth of rendering time (unless you had a high 060/PPC)
