Manufacturer and type number of the chip used could be the key to finding a driver.

Also, which OS you want drivers for is also usually a good idea...

Trying to use with Dos/WFW

There are three main this:
NCR
Racal-Datacom
92C143, 92C140 and 92C110C

Thought it may be a NI6510, but WFW is not working with that driver. Complains about the network responding incorrectly

Can you post a picture of front and back? Might help one of us identify it more easily.

Thanks. Sadly that didn't help me. What's the faint text on the right (as seen in your photo) edge of the card, next to the 92C110C? And on the top edge of the rear of the board (only need long string, I see manufacturer and the part number) and along the right side? Can't find anything from the number on the leftmost label. Never know, one of them might be easier to find

Also, it might be worth trying it with Windows 95, to see if it can identify the card and tell what drivers are compatible. Bit of a rigmarole, but that might help.

Think I tracked it down. Looks like a InterLan AT. Now just need to find WFW drivers. Found netware and DOS so far.

But just noticed the surface mount part that is half off, which is likely not helping things.
