No promises here, but I've been dabbling in sending data between a II and
Mac using the tape interface. I managed to successfully send a 16KB file to
my Mac, but the programs are not ready for general use yet.

My idea is to have one program running on the Apple II which will encode a
file (in real time) and send it as audio. On the other end you record it
with your favourite sound recording program, then transfer the file into an
Apple II emulator. The decoding program runs in the emulator (so it will
work on Mac, Linux, Windows, Amiga, BeOS...) and turns the audio data back
into a file or disk image. To send a file to the Apple II the encoding
program runs in the emulator and turns a file into an audio file. Your
favourite sound playing program then sends this to the Apple II in chunks
which the real Apple II can decode in real time and save when it's memory is
full.

I'll continue to work on it when I get the time!

That said, your best bet is a serial interface, if you have one.
Transferring data via your computer's audio hardware limits you to only a
few hundred bytes per second.
