Gray Research CBS color monitor
The Early Television Museum has just acquired a Gray Research field sequential studio monitor made in 1951. It is a monster, about 32 inches on a side. I've posted a bunch of high resolution photos at http://www.earlytelevision.org/Template.html (about 8 mb). A lower definition photo and some information is at http://www.earlytelevision.org/gray_monitor.html

Steve,
Those 5181 high brightness (4.2KW xenon) Eidophor light valve projectors I have originally came outfitted with field sequential color 441/180 as I recall and I have all rotating dichroic filters, electronics and test patter generator that came with them. That's right, I have an actual field sequential color bar and test pattern generator. The F.S. color equipment could be used with other B&W equipment, for example to make a F.S. color camera from a B&W. I had the Eidphor running making a color test pattern before I changed the scan rates to 525/60 and disabled the color circuitry. It would be simple to re-install. Contact me if interested. I don't need this stuff anymore. Rob

Facinating set Steve, any chance it can be restored to functional at some future date?

CBS Color Monitor
We are well along on bringing the Gray Research monitor and the two surviving field sequential receivers back to life. The monitor's progress can be seen here: http://www.earlytelevision.org/gray_restoration.html
To get these things working we have to design a signal source. We are building a color bar/gray scale generator for the old CBS standard: http://www.earlytelevision.org/cbs_sync_generator.html Eventually we are planning to get a 1950's CBS field sequential camera working.
