Hello,
I recently got this Yamaha YMF704-s OPL4 GM MIDI module and my understanding is that this is a proprietary module to be used on Intel's 440FX Portland motherboards equipped with YMF715 sound chips.
You can see on the motherboard's manual that this module was supposed to be connected to pins J7C1 and J7D1:

I don't have one of this motherboards, and it's not a great motherboard anyway since it only supports Pentium II up to 266Mhz and has no AGP slot.
So my question is, and I know it's a long shot, would it possible to wire it somehow to a regular wavetable header on a ISA soundcard?
Thanks in advance.
