@bryansmart @cordova5029 @simon Ah yes the good old days of the Reading Edge. I didn't get my first laptop until 2001, and was mostly done with college by then, so I remember hooking up one of those big 4-track recorders so I could get the audio output. And math plus physics plus economics all had separat e tutors and tons of out-of-class lab time to get the work done.
