It was also possible to record by sampling one of the parallel port pins. Lousy sound quality, but we manged to record a song and play it back over the speaker, and have it be recognizable.

If you're going to use a parallel port, use a resistor ladder and make a crude DAC out of it.

Great suggestion, but a little late. :) At 19, no EE experience, and only a few months of experience with C, we barely knew what we were doing. We also managed to fry one computer by turning up the amplifier too high.
