hmm maybe this is the drivers you are looking for. The soundcard is from around 1995-1996.

It is a old soundcard, since it have a IDE port on it to, to support a cdrom drive.
Really have no clue if this card have any sound blaster compatible mode, or similar.
my suggestion is to try buy maybe a Sound blaster 16, or sound blaster awe64 isa soundcard.
If you do find a sound blaster awe 64 Value/gold isa card, i could mail you my startupfiles, with all the drivers needed, to get cdrom/mouse/soundcard/ ect. to work.
My old system is:
Pentium-S 133Mhz
64mb edo ram.
intel motherboard.
2x or 4x toshiba cdrom drive.
850mb conner harddrive.
trident pci 9680-1 graphic card.
creative sound blaster awe 64 value isa soundcard.
