I was thinking more of building a PCI card with higher-quality filters than
the OPL3s and SIDs, like SEM chips for example, and it's own mixer and
analog out. The same design could then work in current generation computers,
or alternatively be used in an old cheap one. The thing I liked about those
old PCs was, they didn't need fans :)

I think the The SNR is the problem. Lots of noise feedthrough on the ground
lines from the digital circuits.
