Speaking from decades of experience, you *do not* put a Unibus machine
together in a big configuration, especially from mix-and-match used
parts, and get it to work. You go down to the most basic configuration
possible, and then add parts one at a time, testing as you go.
I'd recommend that anyone in a situation similar to yours strip the
machine down to a single system unit (i.e. pull the M9202 linking
the backplane segments together and put a terminator in slot 14),
with a single memory board and a single disk-like peripheral, then
work their way up. Of course, you need a terminator before you can
do any of this, and preferably a few spare grant continuity cards
(but we'll make sure these shortcomings are fixed shortly!)
