Whoops.... I thought you meant 7ISA + the ones you listed. Confusion would have been eliminated with a colon ":"

No... not much of value there. Can you be more specific which XG cards those are? It's doubtful, but they may be the ones with the really good synth set that would make General MIDI sound quite good for a classic DOS box.
EDIT! Never mind... I did some digging on "YMF719E-S" and it turns out to be just a boring old FM synth - nothing worth keeping.
