Does anyone know if the CPU assemblies (A10 I believe in the service manual) are interchangeable between the 16700A,16702A and the 16700B, 16702B?
I basically have a 16702B with a busted CPU board and I'm looking for a cheap replacement, and the cheaper buys are usually in the "A" line.
They have different part numbers in their respective service manuals, but basically the boards _look_ almost exactly the same, apart from few slight changes (Some great photos at http://jvgavila.com/hp16700.htm). The only significant change seems to be that the "A" line had an RJ45 jack installed for the on-board 10Mbps ethernet, while the "B" line didn't have the RJ45 jack installed so that the 100Mbps ethernet daughterboard would fit.
I'm guessing that I can substitute in an "A" series board and it should work fine (but with the slower ethernet) as they both have the same CPU (A 150Mhz PA-7300LC).
Any experience or knowledge of this realm though is greatly appreciated. Thanks!

The 16700B series had a MUCH Faster CPU (slightly tongue-in-cheek, we went from a 100 MHz PA-RISC CPU to a 150 MHz one). The other important difference was the B version had twice as much RAM in the system which made a HUGE difference in virtual memory swapping performance. I think they went from 128 Mbytes to 256, or maybe it was 256 to 512.
Anyway you might be able to use the older cheaper motherboard but be prepared to wait on things.
I used to write software for that platform, I've since joined the sales force so I can't resist saying maybe you should look into a 1680A or even a 1690A series, or our currently active 16800 analyzers. I know if you're looking at an old 16702A it might be outside of your budget but we do have trade-in programs even for old ones sometimes...
Good luck,
