I wrote about my HP 16702A not working on Ethernet any more.

I tried it. Didn't work. I also tried connecting the 10base2 to a 10
Mbps hub, and another port to my "real" network, and that still didn't
As HP-UX boots, it says:
<timestamp> auto_parms >> Network was disabled by boot scripts on
previous oot. Re-activating the network.
8/16/6 <macaddr> 0 UP lan0 DOWN 4 ETHER Yes 52
<timestamp> auto_parms >> /sbin/auto_parms, checking network for DHCP
server (see /etc/auto_parms.log)
Then in the progress list, it shows:
Configure LAN interfaces .................... [FAIL] *
Check LAN Status .............................. [N/A ]
Configure HP Ethernet interfaces ......... [ OK ]
Configure HP 100BT interfaces ............ [N/A ]
Configure LAN interfaces ..................... [ OK ]
Then once the logic analyzer application is up, it shows an error log
window, which says
There was a DHCP error . Network was disabled.
But if I go to network settings, it says:
Network hardware not usable - Is the network connected?
And all of the radio buttons (e.g., to select "standard" configuration
instead of DHCP) are greyed out and I can't configure it.
I think the Ethernet ports on this beast are dead. :-(
I'm not sure whether it's the CPU board or the I/O board that is dead,
but Keysight, or whoever they are this week, wants more money for
either of those boards than eBay pricing for a used 16700A or 16702A.
