Yamaha DB50XG stand alone soundcard

There are a number of daughterboards that can be added to Sound Blaster (clone) cards to produce a much better sound than the internal FM chip. One of these is the Yamaha DB50XG sound card, which is relatively cheap and widely available. Those of you who would like to use this card but do not have a suitable sound card for the PC, the DB50XG can be used as a stand-alone sound card with superb MIDI wavetable sound quality, simply by adding some hardware and a suitable power supply as shown here. The additional hardware allows the DB50XG to be driven by any MlDI source, whether computer or musical keyboard.
