I'll try TAPir with these WAV files that I have already made.

All of the tapes are for PET/CBM.  I noticed both TAPir and mtap have options 
to select a computer type but no PET/CBM option on either.  Does this matter?

Thanks for this info.  I'll save .tap instead of .prg so we don't lose data.

I found the schematic here: http://sta.c64.org/x1531c.html

I'll build the cable and try it.

Thanks,
