Rob, although I don't have a physical 68K mac, I would use 68K version, so that I can have the luxury of working on mac versions of NumPy codes under MAE on my Sun workstation; MAE emulates a 68K mac. The actual mac's I have access to are all PPC's, though, so this is not essential. But I got used to being able to do this under 1.4. -Ron Cohen-
