I bought a cross-over ethernet cable and connected my old 7200/75 to my 
new iMac so I can transfer my files to the new machine. I've never used 
networking before, and I can't get the two machines to talk. I think the 
problem is the Appletalk control panel in Sys 7.6.1 on the 7200 doesn't 
have a selection for ethernet, just modem port or printer port. What am I 
doing wrong? File sharing is on, and Appletalk is set to active.

I also may not have all the files necessary for networking installed, 
since I had removed them because I wasn't using networking. In the 
extensions folder I have:

Apple Built-In Ethernet
AppleShare
ENET Compatability
Ethertalk Phase 2
File Sharing Extension
Network Extension
Open Tpt AppleTalk Library
OpenTptAppleTalkLib

In the control panels folder I have:
AppleTalk
File Sharing Monitor
Sharing Setup
Users & Groups

All help is appreciated. Thanks
