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
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.)
