For the price of 20 1% resistors and a plug, with no power supply needed
you can make a D/A converter.
You need one plug for your amp, one for your parallel port and 9 20k and 9
10K resistors Use 1% resistors if possible <20> and 20k sound much better than
22k.

This circuit was included in an Amiga mod file player package by Mark J.
Cox. He acknowledges Harry Stox for the circuit. I have tested it and found it
to be pure gold.
