That's a pretty sweet CC you've got there. My guess is you're missing the networking software from system 7.5.3. I don't recall if it's installed with the default installation, particularly on Macs without built-in network hardware, but it's certainly an option that may have been omitted, cramped for hard disk space. You need, at minimum, Apple's driver (extension) for your ethernet card. I'd look up the exact file names in case you wanted to go the TomeViewer route if I didn't have my Quicksilver server temporarily burning a DVD project where I usually keep a 68k machine set up.
If you have the system disks, just run the Installer, choose to do a custom install, and select to update the networking software. If you don't have the system disks, you'll need to
download and make them from Apple's website.
Also, do yourself a favor and install the free upgrade to System 7.5.5, also
available online.
G'luck,
Cody
