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

Assuming you are using 10BT for the network
connection, do
you have the terminator cap installed on the 10B2 BNC jack? I think
some things don't work right with the 16700A/16702A network without
that terminator cap installed.
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
work.
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.

I've never had a 16700 series fail that way before, at least not yet.
I've had a couple of 16600 series CPU / interface boards that have
failed being able to communicate with the logic acquisition board.
Those are almost identical CPU / interface boards to the 16700 series.
No real surprise that Keysight would want way more for a replacement
board than the current market value for a complete used mainframe.
That's pretty much the way it always works.
If you look around you could probably find a complete working 16700A
or 16700B shipped to you for $100 or less. Then either use them with
an external monitor instead of your 16702A, or transplant the 16700A
parts into your 16702A if you want to keep using the built-in LCD
monitor.
I have one 16700A that no longer powers on. If just the power supply
is dead I might consider parting out the CPU and interface boards.

(One thing that is interesting on the 16700 CPU board are an
MP9914FNL, 75ALS160, 75ALS164, and an unused 24-pin connector. I
wonder if there is GPIB capability hidden in the system.)

If this uses an AUI cable to an Ethernet tap, it is possible
the diags don't work without something connected to the AUI
cable. Just totally guessing!

Actually the LCD monitor in the 16702A was dead when I got it, which
was probably why I got a good deal. Since the resolution of the LCD is
so low, it's much more usable with an external monitor anyhow. I just
wish that there was a setting for 1600x1200 at 60Hz, or that there was
a way to set up the "custom" display setting.

I have a 16701A that doesn't power up. I haven't yet tried to sort
that out. I haven't really ever need more than five acquisition cards.

Are those chips actually loaded? Maybe they used them for manufacturing test?
I did think that one of the things they screwed up on the 16700 series
was not supporting HP-IB and the command set of the 16500 series.
Don't even get me started on the 16900 series, though.

For the time, they were pretty advanced, especially in comparison to the
likes of Biomation or Tek 'scope plug-ins. I don't think it's fair to
grouse about them, wishing that they were something that they're not.

My bad--I misread it as "16000". Damned type fonts and bad eyes...
It's what, Keysight, used to be Agilent, used to be HP? Wonder what
Bill and Dave would have thought about the latest round of slicing and
dicing....

Yep, they're present on every board I've seen. They're in the upper
