[net.audio] Turntable speeds

moroney@jon.DEC (09/29/84)

My grandfather was legally blind the last few years of his life and he
subscribed to the talking book program sponsered by the Library of
Congress.  He got a special cassette player and a special turntable
to play the talking books.  The turntable was at 8-1/3 RPM!  The special
records seemed to last forever.  It had pretty good frequency response if
all you are interested is 300-3000 Hz :-)  Unfortunately, he was unable to
use it since he lost his coordination, too. The cassette player had 4 tracks
and also ran a lot slower than normal (15/16 IPS - eat your hearts out, golden
ears :-) )  The average book (remember, this is SPOKEN) fit on 3 cassettes.
Those were a lot easier for him to use.
