It looks like it does require a dedicated power supply. I saw your request on another group site which showed one link:
No pictures of the back, but all the specs I could find show it needs a dedicated (well it’s also apparently used on similar models) power supply for the console, plus a relay switch unit.
I couldn’t find any other components for that rig, considering limited time to research. I hope your interest in it is as an antique … My guess is that except for luck, this is going to be a boat anchor restoration project, so you will need time and patience and electronics know-how to locate the other vintage components & make it work. Even then they may require parts replacement, etc.
Even the only manual section I found just had some front pages, i.e., missing pertinent data and schematics.
