The "prototype PC 70 Cameras" Harold Deppe referred to were actually PC 60 Cameras built by Phillips in Eindhoven, Netherlands.  These were a European version of a Plumbicon Color Camera. By the way, it might be of interest to some that the Plumbicon tube was not a Dutch development.  It actually was developed at the North American Philips labs in New York State.

There never was a prototype PC 70 Camera.  Both Dick Dunn and I were working for North American Phillips in Mount Vernon, NY. where we were developing the American version of the PC 60.  That became known as the Norelco PC 70.  "Norelco" was the US Brand Name used by North American Philips.  The PC 70 had some new circuitry and the base equipment was modularized for rack mounting.  You all remember the "great east coast blackout' of the early '60's.  This is a true story.  Dick Dunn had just completed the new video card for the PC 70 and the blackout occurred exactly at the time he plugged in the video card for the first time! For years I kidded Dick that he was the REAL cause of the blackout.

P.S. The PC-70 wiring was basically all the same color... what a pain in the *** to troubleshoot!
