installing new ethernet address equipment with VMS 6.1

Hope this helps for solving the Rinaldo> installation problem. I'm getting a bit lost in your wording here. Why do you care about the Ethernet address? I don't think DEC stuff does. The Ethernet MAC address in most DEC stuff -- anything other than a PC NIC -- should live in a 32x8 PROM, quite possibly socketed. You can swap it out. Or you could blast your own if you can find the PROM, which may not be easy. The pattern should be in one of the public DECnet specs (either the Ethernet Datalink spec, or the Node Product Architecture spec). It contains several copies of the MAC address with a checksum, and a check pattern. paul
