Seeking Drivers for Unknown Apple Ethernet Card?

rbanffy asks: "Does anybody know what this card is? I am resurrecting an old Macintosh LC II and would like to attach it to a network. The card was inside it, but the hard disk had no drivers. It is an LC-PDS Ethernet card with RJ-45 and BNC connectors. The important parts seem to be a SMC 91c92 chip and an EPROM (haven't seen one in years) labeled 'LC ROM 44F0'. Could one of you can identify this critter and point me to the correct drivers?"
