I wonder if Agilent did that on purpose to limit the lifetime of their boards?
@MarkL: how did you repair them? Did you just bridge the missing part of the trace or reroute the connection entirely with wire?

Edit: The search test still hasn't completed after two hours. pv prints the following at the start then waits:
...
With the1756x1675x cards, some of the debug printout references to "Chip x" means "Ux". If true here, there could be an issue related to U8. All 0's looks strange. Perhaps focus on that area and all the connecting traces to and from that area.
If you haven't read it yet, go through the Service Guide Self Test and Theory sections. Although there's no schematics (much grumbling here), there's sometimes useful clues:
Why was "searchTest" showing up as untested? Did you run the tests manually one by one? Perhaps play with different values for debug, result, or mode. Maybe it will print out more detail of what it's doing for searchTest. Also, if you set debug mode 1 and then type help, does anything extra show up for the 16760A card?

Other than that all signals that dont fail the selftest could still work.
Maybe test that with a function generator?
On the 16700 HPUX-running chassis, you can turn on debugging when invoking the top level GUI, /usr/sprockets/bin/vp:
usage: vp [-debugqfxa]
[-debug level]
[-all] (load all shared library groups)
[-q] (don't show intro screen, don't prebuild instrument menus)
[-f cfgfile] (load this config file at powerup)
[-x] (exit after powerup, typically used w/ -f option)
[-a address]
address < 0: don't load instruments
address > 5: search all scsi addresses (the default)
address = 0-5: search only this scsi address
vp -debug 255
yields a debug menu on the 16760A. (Screenshots attached. The comparator window has a few more options than the 16756A.) I was incorrect earlier when I wrote about the app locking up when capturing from the card. It runs just fine, but locks up when trying to view the data. When trying to capture and view pod 1, the following message is printed to the console:KatanaHardware::ramSearchStart()

Wow that SCSI bit is realy interesting. In the documentation they write something like propriatary multiplexed 16-bit bus.
The LA connector has 72 pins, SCSI 50 or 68 if I remember correctly, but definitly close enough.
Would really be quite ingenious to do it that way because all the ip for the fpgas would already been there and tested.
Also quite impressed with the debug options, havent had time to see if the 16902a has something like that as well, would be really helpful.

Also, some of the bits are oscillating with no cables attached. (Third screenshot.) They looking like they might be physically adjacent on the card.
I can't mess with the threshold settings since I don't have a probe to go on the end of the cable. According to the service manual, the LA communicates with the probe over I2C to identify which type it is. Does anyone have information on what the LA expects to find there? (Perhaps a small EEPROM?) This would also be helpful for people who can't afford the 90-pin probe prices.
...
Does anyone know which devices are responsible for setting the threshold voltages?
...
I haven't done any debugging on the comparator or threshold circuits, but I would start with identifying the DAC (U39) outputs for the 8 pods. Then compare the out-of-spec output with some of the working ones all the way to the comparators (U29 U38 U46 U53 U72 U79 U85 U88). The DAC (U39) is an AD7841AS in a MQFP-44 and is near the backplane connector.
...
If the reference was off then more than one 8 bit section would be affected. There are three reference connections available on the DAC but minimum of two outputs using the same ref. I guess the reference will common to all of them?
So carry out continuity checks between the DAC outputs and the resistor divider you mention. Check resistor values and connections to comparators.
