So close... The simpler one is the 9810, but alas I don't have a 9820.
The more comlicated one is the 9830

I've seriously 'investigated' (you, having met me at the HPCC conference,
will know what that means :-)) the 9810 and 9830. Obviously I've not done
the 9820 as I don't have one, but I know that many of the PCBs are common
to the 9810 and 9820 (the entire CPU board set, the main backplane, I
think the PSU, and maybe some parts of the memory system). If I can be of
any help, feel feee to ask.
