hi ken, I would be interested in a book on the history of screen readers and access technology if you ever wrote it I would buy it. I know keynote gold was made by Berkeley text-to-speech systems in the late 80s. And Berkeley was bought by l&h lernout and hauspie, which was bought out by scansoft which was bought out by Nuance and Nuance also bought speech works international, who previously bought eloquent technologies.
