What is it?

It is an internal sound card with the OPL3 chip (Sound Blaster 16 FM compatible). The schematic is based on texelec board Resound Resound v1.1

If you are interested in the fully assembled version, you can get it from the following Tindie product sheet

Why did you make it?

Because texelec decided to publicly share the schematics of its Resound OPL3 sound card, I decided to make a version compatible with cases that contain HDAudio connector and microphone and speaker jacks on its front.

I have a Monotech NuXT board based on Sergey's Micro8088 integrated into such a casing, so I decided to cover this need by adapting the scheme, and by the way, manage different I/O ports through the use of a SPLD, more information about the whole process here.
