I have installed all drivers for all network cards, and Apple's TCP/IP is installed by default in both Mac OS 8.5 and 9.1. I have connected this misbehaving Mac to modern 10/100 ethernet switches and hubs, older 10-base-T hubs, and to another older Mac via a crossover ethernet cable. In all instances, all OSes patently refuse to see an ethernet card of any kind in this machine. I am nearly convinced the logic board is somehow goofed up, but still hold out hope that just maybe, the dead PRAM battery is the culprit. Help? :P
