Those red cables appear to be SDI - maybe that spot was an RA80/RA81?
The boards appear to be correct for a UDA50 (M7485/M7486, but it's hard
to make out the board numbers).

Blurry photo, but it looks like there are a 4x3, a 3x3, and a 3x5 Molex
connector, and two brown mini-modules protruding from the right side.
If so, then what purpose did it likely serve?
It's not a DEC power supply, it's a Fujitsu power supply, likely for an
M2284 SMD drive. Probably went in the empty slot you mention below.
