The LAN connector is compatible with the AppleTalk networking port, there's one in my TT or in the Falcon030 also. As far as the computer's concerned, it's just a high speed serial port, you can put Apple Mac Modems and printers on this port for higher port speeds! But there is no networking software that I know of...you could maybe use MiNT or Linux (I know MiNTNET works OK) but there were never any industry standard drivers for it to attach to corporate networks.
