Many of the modules in your telecine photo are common to the KCU electronics - especially power supplies. I think Fernseh must have sold their equipment by the kilogram - they certainly couldn't be accused of being 'too light weight'
This photo shows one KCU with a rack I've assembled with the minimum supporting electronics to run the camera. From the bottom:
Video processing 4ru
Power supplies 4ru
PAL coder and colour shading 4ru
Tek SPG 2ru
OCP - two there, have to remove one and replace it with a mono-knob! 6ru
System Video WFM & VS - strictly speaking these are optional 3ru
The 23u rack as shown must be close on 200Kg
And no room for a pix mon.
Camera is on a Vinten Mk3 head, atop a Vinten HP419 pedestal c1960
