Looks like the hardware is good! I'm able to hit internal IPs (on the local 192.168.* network) with ping, browser, and telnet. I'm not able to get out to the internet yet, but I think that's a MacTCP issue. I'm not really sure how to set it up. I have the proper gateway and router settings, but it's not happy about something. This is on the SE/30 that I bought on Saturday.
