Because my Variax 700 somehow got its brain scrambled in storage, learning how to A: recalibrate the model selection encoder and B: get Workbench 1.75 running on ANY Mac around here has been a nagging priority. I can't thank you enough for the introduction to Pacifist. This worked exactly as described, and now I've got the encoder fixed (different process altogether) AND Workbench running on Yosemite. Yes!!! Thanks for the info!
