> Back in the day, the parallel port was awesome for hobbyist hardware hacking. R-2R Soundcard! Soundblasters were crazily expensive (and a Gravis UltraSound even more), but you could solder a R-2R resistor ladder [1] connected to the parallel port, and have pretty decent soundcard (well, at least when compared to the onboard speaker) for $10 or less [2]. Not many games worked with it, but it was quite popular amongst the demoscene at the time.
