Jules,
We recently managed to (finally!) get our HP 2116
machines out of 'deep store'
and into the light of day, and some initial cleaning work was done on the
panels earlier.
It appears that many of the boards, especially in the 2116C, have just
been placed into arbitrary slots.
You will also need to double-check some of the part numbers on the boards
to be sure that the 2116B and 2116C boards have not been put into the
wrong chassis. For example, it may be that some of the boards in the
2116B are 2116C boards and vice versa.
I can send you a more complete list of which boards belong in which
slots, but that will be just part of the story, in order to get these
machines running.
Overall, it looks like you have close to a complete 2116C and 2116B,
though you are missing the I/O boards that would have been used
in a dual processor system.
