Yes, it needs power and ground (for the terminators and buffers) but
has no other connections to the backplane.

You need it.  I can't remember if it's the READY line or the WR.PROT
that usually ends up in the wrong state otherwise, but one of them
needs to be there (the READY line has to be grounded, IIRC).

You can kludge it pretty easily.  The layout and schematic for the
M9058 distribution board are on my web site, along with the schematic
for the LEDS-and-switches circuit.
