Pin 2 is TXD+ so I suppose that the RX side still works. I have no
suitable storage for this system (well, I have some RF71 drives but not
the carriers that would be needed to connect to the backplane properly),
so I was planning to netboot from a SIMH instance on a PC. However, to
configure that I would need the ethernet MAC address, and I can't think
of a simple way to get that. unless someone knows whether the ethernet
ID prom is readable in something like a TL866II Plus?
Assuming you find a solution for the console port issue, can't you just
try netbooting it and see what mac address the load requests have?
You could either use some ethernet monitoring software such as tcpdump,
ethermon, wireshark or whatever or your MOP server may even report
load requests it sees on the network to OPCOM.
