No blood has been spilled - yet! I think it's waiting for the right moment.
Originally I was just going to use a YMF718 card for audio, but I thought it would be nice to have a real SB16 as well for compatibility's sake. EMU8000 is nice to have too so I picked up this AWE32 CT3780. This one doesn't have CQM, memory slots or a wavetable header. I'm finding that AWE32s are much less common on UK eBay than AWE64's at the moment. Even AWE64 Gold are quite common.

Unfortunately, although the card was advertised as tested, the FM and AWE tests in diagnose.exe both produced static. I guess the seller just tested wave output in Windows. Inspecting the card showed up a few broken traces 😠

The larger broken trace on the right is a +ve supply voltage to the EMU8000 section of the board. The break on the left only affected one trace, a digital output from the EMU8000 to a DAC in the output stage. The larger break was fairly straightforward to bridge after scraping back the green coating to reveal fresh copper.

I wasn't confident of bridging the smaller break without damaging the surrounding traces so I decided to run a jumper wire between the two nearest vias, unfortunately this was quite a distance. I used epoxy to cover the vias and bond the jumper to the pcb after soldering.

With these fixes FM and AWE output work again, which was a nice payoff. I'm still planning to run the YMF718 alongside to handle MIDI and the XR385.
