I have set up a PowerBook 1400 Series. PowerBook 1400CS. I have a PowerBook 1400C with a built in ethernet. These ancient dinosaurs both work. And One of them gets online with Classilla. But the PowerBook 1400CS does not have a built in Ethernet. It has PCMCIA PC Card Slots. Are there any Ethernet Adapters that will fit and will work with the PowerBook 1400 Series? Hopefully I can find one that takes up only one slot, and has an adapter cable. (I have an ancient IBM 600E with PCMCIA PC Card Slots. One has a Wifi Wireless Lan Antenna in one slot, and the other slot has another PC Card which has a port in it and in that port is an adapter cable and on the other end of the adapter cable there is an Ethernet port.... ) I would like to find an Ethernet PC Card for the PowerBook 1400 Series that would take one slot, not two, if possible.
