Can I convert a PB 1400's PC card port to a ethernet port for file sharing?

Question

My plan here is to connect a PowerBook 1400cs/133 running OS 8.6 to an iBook G4 running OS 10.4 by means of an ethernet crossover cable, and move my important files (ClarisWorks 4.0 docs and games mostly) to the new computer. But the PB 1400 has no ethernet port! Is there something I can put in the PC card slot that will convert it to an ethernet port?

Answer 1

jpl, Denis, here's my setup:
The PB 1400 is connected to the iBook via a Farallon EtherWave/EtherMac Ethernet PC Card (with a blue arrow, PCMCIA 2.1, PC Card Standard). I have the Farallon software installed and the Farallon extension turned on. A "Farallon EN Card" icon appears on my desktop, and the little light on the cord where it connects to the card is green. I used to use the card to connect to the internet back in the day when the 1400 was my primary computer, so I'm confident it works.
The PB 1400 (name: Ben's PowerBook 1400): AppleTalk, configured to connect via alternate ethernet. File sharing, on. TCP/IP, connected via AppleTalk (Mac IP). I've tried configuring that both "Using Mac IP server" and manually by entering in the iBook's IP address and router address (the 1400 is not connected to the internet). As far as I can tell, Users/Groups is configured; it has "Ben" as "user" and "Guest" as "guest user."
The iBook (name: Ben's iBook G4) is set up basically identical to the way jpl describes his iMac above. Like his, the services panel of sharing on the iBook says "Other Macintosh users can access your computer at afp://x.x.x.6." I also manually entered the iBook's IP address, subnet mask, and router. Under my shared location, under Built-in Ethernet, TCP/IP is configured and AppleTalk is active.
Still, file sharing is not working. When I try to access the iBook from the 1400, I go to the Chooser, click the AppleShare icon, and "Ben's iBook G4" in the file server window. When I select it and click OK, I go to a screen to enter my name (Ben) and password as a registered user. I'm not sure if the password it wants is the file sharing password I set up for the 1400 or the administrator password for the iBook, so I tried them both. I also tried connecting as a "guest." In all cases, after I hit the "Connect" button, I got the error message "The connection to this server has been unexpectedly broken."
No luck going the opposite direction either. When I go to Go: Connect to Server: Browse on the iBook, "Ben's PowerBook 1400" appears in the Network area, but when I select it and hit the "connect" button, I get this error message: "The file server uses an incompatible version of the AFP protocol. You cannot connect to it."
