Hi everyone :) After noting that Mac OSX has rio usb 'plugins' but no good app (well, iTunes, but it is limited to erase, download music and upgrade firmware), I set about writing one. I currently have all the usb stuff working fine but only have the control codes for reading folder blocks and uploading an ani file. These I got from other opensource stuff on linux. I was wondering if anyone had a list of the codes and a quick rundown of some of the more involved ones :) Mac OS X does not use device drivers like linux does so source code would be not much more help than a planetext listing. I'm also looking at the 600 and 800 and wondering if they have any cool stuff going on in them I could make available to os X users :) Hope someone can help Yours Robert Goldsmith dept.
