Subj: REPLY TO MSG #2719 (ACOUSTIC COUPLER)

Updating my previous message, I finally found a copy of INSIDE THE MODEL 100,
which discusses the acoustic coupler. I need to build an amplifier for the
audio and I need to power the electret microphone. However, I don't know how
much gain is necessary for the amplifier. I can experiment, but I'm hoping some
"old hand" at computing can help me out. You newbies probably have never seen
an acoustic coupler, much less had to build one yourself! What are we coming
to?
