I would like to know information about these two cards that I got from ebay.

Hi all.
I bought a sound card and an IO card from eBay.
But I couldn't find any information on them even after searching.

For the sound card, I most need a DOS install driver.
(Unisound does not recognize it).
For the IO card, I am most curious about the jumper settings.

Even a small hint would be appreciated.
Thanks to the forum users for always being so helpful.

The io card is a 2 serial, 1 parallel, clock, game port, and floppy adapter, cheaped out by leaving off one of the UARTS and pair of line driver chips. My guess is the 8 bit dip switch has:
2 switches for serial A port address, 1 switch for serial A irq 3/4.
2 switches for serial B port address, 1 switch for serial B irq 3/4.
1 switch for parallel port address, 1 switch for parallel irq 5/7.
With everything else at the normal addresses.

The sound card is one I've never seen. Maybe right before Plug-n-Play was a thing, although it would be worth trying it on a PNP capable motherboard. Probably needs a dos utility to configure the settings.

The sound card looks like a Windows Sound System knockoff with a CD-ROM interface added.
