Breakout board for a Waveblaster based MIDI Synthesizer
This uses a Maxim MAX743 to derive the +/- 12 volt power supply required

This circuit is designed to mount a Waveblaster type MIDI synthesizer in an external box, as opposed to mounting it on a old style ISA Sound Blaster sound card, which is now obsolete and no longer able to be used with a modern computer. With this I can now use the old synthesizers on a modern PC.

This is an MP3 recording of the music from an old game called Descent, recorded on a Yamaha DB50XG synthesizer, using this circuit board:

I've also made some Youtube videos of game introductions using various MIDI synthesizers.
This is one I've made myself of the Star Wars Tie Fighter game introduction sequence, using the Roland SCB-55 Synthesizer:
Tie Fighter (Roland)
Compared to this video (made by another) which uses an Adlib sound card, there is a noticeable difference in quality:
