Archiving tapes

Hi
 Almost all of the tape programs use a serial like output.
It takes only small modifications to the tape dump programs
to send to the RS232 serial port instead of the tape port.
You can then send the programs in digital form to your
other machine.
 It does require a simple serial reader program to take
the serial information back into memory. I've done this
in order to archive tapes that I have for the Poly 88.
The digital form is a little more robust than the audio
tapes and you can even feed it through a disassembler.
 Once the information is transferred back into the original
computer, one can generate fresh tapes to play with.
 This avoids all the issues with trying to make good
copies of the audio signals.
