Here you go: genuinesoundware.com, go to products, at the bottom, legacy donationware plugins. I couldn't post a link because I don't have 5 posts?
These are all the freeware versions, which are very good. You get a Rhodes, B3, Wurlitzer, effects, Leslie. These are some of the best plugins with versions for Mac & PC. If you like this B3 emulation their paid VB3 is even better, many people, myself included think it is the best software B3 out there. Much better than Native Instruments B4 ll.
