Gray Research 1101 Field Sequential Monitor
This is a studio monitor made in 1950 for use with the CBS field
sequential color system. It has a 10 inch picture tube with a color
wheel in front of it. This unit is missing its wheel, motor, and lens. It is the only known surviving field sequential
studio monitor. Click for more

We have completed
restoring the monitor, and have built a color
bar generator for the CBS field sequential system. In addition, Darryl Hock
has built a NTSC-CBS converter
converter to allow broadcast TV to be viewed.
