I just went back over my Tech notes and early issues of ANTIC magazine, and
it appears that Kenneth Sumrall is right... the 410 cassette recorder does
contain FSK demodulating circuitry to decode the audio tones into logic
level data streams...  (must be the mists of time fogging my memory, but
I thought I remembered being able to input data from a regular recorder...
after thinking about it though, I think I *did* have to use the 410 to
actually LOAD the cassettes back in...  but I was able to record the output
from the SIO port successfully (more or less) on a regular audio recorder,
which was my goal anyway, in trying to mass-duplicate cassettes...)

What's even more interesting was a note I found in ANTIC, Volume 1, No. 1,
which refers to a "Tape Operating System", which they abbreviate as "TOS"..
 
Now where have I heard those letters before...?     :)
