This Plotting Computer is comprised of 3 clear disks with linear black, green, and blue markings that rotate about an axis at the center of a fixed circle marked in degrees. A clear hinged and latched polycarbonate lid overlays the active elements of the device. We assume that this was used in an instructional setting, but know nothing else about this device.
