I keep messing around with Ted Rossin's circuit & s/w.
the website is gone but i saved the files a few times and archive.org
has a recent backup of the schematic
https://web.archive.org/web/20170302024947/www.tedrossin.net46.net/Electronics/Pic/Schematics/CassetteInt.jpg
if the circuit interests you i'll dig out the zip file with the software
and everything in it.

I'm running an idea through my head and I'd like to bounce it off you guys.
The idea is to create a virtual cassette recorder/player. Possibly
for my T102, but also for the pocket computers that I have.
I've found this
(https://www.tindie.com/products/masihvahida/audio-stereo-sound-player--recorder-module/)
which is pretty much done. I would just have to hook up an RS-232
shifter and sacrifice a cassette cable for my T102.
I've also found this
(https://www.tindie.com/products/masihvahida/soundduino--audio-shield-for-arduino/)
that I'd have to do my own programming for as well as add an Arduino.
This one also has normal 3.5mm jacks, so no cable sacrifice needed.
The idea would be that I could use CSAVE and record a WAV file onto
the SD card and use CLOAD to read it back in when I wanted. I've seen
this offered as a way to load software for pocket computers using
their cassette interface and the sound inputs/outputs on a PC.
