Hi Janina: With the cvs code you certainly can boot with the synth either turned off or not connected. There isn't much if any performance hit as you call it. I was planning on not releasing a new version of speakup until I had the synth modules stuff written, but a number of folks have been lobbying for a new release before then. I'd be interrested in hearing folks opinion on this subject. Kirk -- Kirk Reiser The Computer Braille Facility e-mail: kirk at braille.uwo.ca University of Western Ontario phone: (519) 661-3061
