   With a direct connection it should work, playing it back with a PC, I do   
   it all the time. That is, I playback a wav with a program into a TRS-80.   
   And I record programs saved back from the TRS-80, though I use them for   
   wav2cas conversion.   
      
   This is because it is the way I get the best result. I load a small copy   
   program from the PC; COPYIT by Nick Andrew, to my model III, then run it   
   loading programs from cassette and saving them from there to the PC.   
   Then on the PC I convert to cas. The model III is the best at reading   
   tapes, better than my 7 other actual TRS-80 compatible machines and also   
   the PC armed with wav2cas directly. I think it is coincidental that it   
   is best (same circuit, almost on all of them).   
      
   The trick is to get the levels right. The signal into the pc must not be   
   too loud (or you will get clipping noise). As it was in the old days   
   into "the red" but not fully across "the red".   
      
   You might also try the line in input on the pc rather than the   
   microphone input. I'm using the microphone input.   
      
   Then for playback into the TRS-80 the same applies getting the volume right.   
      
   Another problem would be grounding noise, a hum 50/60Hz from the power.   
   This you might get because of ground loops and/or bad capacitors in old   
   powersupplies.
