BOOM - Binocular Omni-Orientation Monitor• Another approach was Another approach was
to use the best display to use the best display technology available technology available (which was CRTs at the (which was CRTs at the time) and to mount them time) and to mount them on a counterbalanced on a counterbalanced arm to offset the weight.arm to offset the weight.
