Couple questions. First, I have a friend who is interested in installing linux. She has an old telesensory reading edge machine that she thinks will act as an external dectalk synth, but isn't sure. anyone know if this is true or not? Hi, it should the version of dectalk software used in that device was dectalk 3.0 not 2.0 as was the external dectalk but if memory serves me right they should be compatible.
