    It is very possible to connect tape cassette to PC's audio-in port such 
as Sound Blaster card so Applewin or other emulators can read/write tape 
cassette directly to the Sound Blaster card.  The problem is that it has to 
deal with tape timing.  The only way is to use Windows Driver Function to 
manipulate audio-in port with exact timing directly to read every bit from 
the tape cassette while storing into memory.  After it is in the memory, it 
tells the emulator that it is time for them to turn by reading bits from the 
memory into tape virtual emulator without depending on the exact timing.
    I have considered in my end already.  I have not written to create 
Windows driver for audio-in and audio-out yet.  I hate to write .WAV.
