Cassette Program FSK Decoding

[+TheBF]

This is something I had never seen.  Thought it might be interesting to the assembled 99ers here.

Interesting. I'll just drop this link to what appears to be a similar linux program here.

Cosby is a program for Linux that will encode and decode the audio

signals sent to and from the data cassette port of a TI99/4a

computer.

I have a liberated chromebook that would be good to use with these.

 

I found a game TIFILE that loads just fine in classic99, but that CS1er insists is NOT a proper TIFILE, and so wont transcode into .wav.  (Oregon trail)  If it can parse that TiFile, I will be happy.

Reminds me of when Information Society included 300 baud modem transmissions on some of their albums.  I wrote an FFT analyzer to decode them.  These days I realize how overkill that was.

Yah.  I called myself, picked up the phone, set the modem to answer, and played the tape into the phone.  Your way sounds far less cluttered.

Try saving it back from Classic99 again with a new name, and see if CS1er likes that.

Already tried that. No dice.
