I have given thought to a serial based "sound card" utilizing a 
microcontroller. The sample data would be sent to the microcontroller's 
RAM and then playback selected by sending a byte (a nibble would 
suffice, 16 samples is heaps) and sending the audio throught to the 
cassette.

I guess comms can happen via the cassette port to keep the connections 
to 1 cable. Power may need to be via a battery.

I should go back and give it a rethink using the Teensey as a base. It 
may be do'able.
