Hi Mark
I also used the original plotter for the MAC many years ago. The new plotter for PC has a number of new features, including export to expo/dev for the palm. This way you can export your film test information including reciprocity information that Phil Davis calculated. I run the plotter for PC on my MAC using crossover, but there are a number of windows XP emulators for the MAC. Also Phil Davis was a MAC person and ran the plotter for PC with one of the emulators on his computer. If you want to upgrade, just give me a call. Thanks
