Well, not to 100%. Especially older Macs (maybe not the PowerBooks) tend to drop that functionality in accordance to their type of ethernet controller, SCSI controller or whatever. For example: my Plus with an Asante EN/SC does not show the MAC adress by this procedure while the SE with the same OS, MacTCP and the same adapter shows the MAC adress.
I am under the assumption that the MAC address is a hardware encoded address. I only have 1 EN/SC right now and they're now geting quite expensive to buy on ebay. So If it is a hardware encoded address, it would not change... Just write the address down for future use...
An Appletalk router... Could my soon to be up and running ethernet ready Performa (LC) 475 act as that router?
Any Mac fitted with the right software can act as an AppleTalk seed router. But have this in mind: a Performa 475 only provides 10Mbit which might slow down Macs that utilize the 100Mbit transfer rates. While this isn´t tragic it can slow down local network connections notably.

I have a Plus, SE, PB145, and theoretically a G3Bronze that all could use the EN/SC. The G3 however is ethernet ready and runs on a cable directly fitted to my Airport Extreme at 100 base-T. It is normally running os x 10.3.9 so I don't think it can be the appletalk router. but that's a diversion.
I hope to get a response from the craigslist poster... otherwise it's off to the electronics shop...
Thanks again,
