A few things come to mind: !. Since the unit is on a long cable, the complex driving circuitry could have been located apart from the display, making for a compact unit, even in the era before complicated ICs, so perhaps it would have been possible. 2. Perhaps the body of the unit could have contained a small monochrome CRT and a mirror/lens system similar to the Philco Safari. Again could have been possible with remote electronics. 3. The caption says "talk to a nurse and operate a combination radio-television set"...Which may be an indication that this was just a "nurse call button" combined with a fancy radio/tv remote control... but it sure looks like a display screen. Scratching my head over this one, thanks for posting it! jr |

As the author states, purple is not possible - but I have no idea what he means by "reddish blue" if it's not purple (which it couldn't be) - maybe he means it was slightly variable from slightly blue to slightly red. Here are some shots of Cliff Benham's 2-color field sequential set (left smaller screen) vs. ordinary 3-color (right screen), from the 2009 Early Television convention.
