Orbit Instrument Corporation made this homely old heavy heavy-duty Trackball. Orbit said that this trackball was issued in 1966. It was installed in a control panel in a Military Air Traffic Control Tower as in the air traffic control photo below.
Orbit Instrument Corp. specializes in products for the Military and Air Traffic Control Systems that require a high degree of operational reliability over extended periods of time. The top plate is approx 8" x 8" and weighs approx 4lbs. The ball looks like an 8 ball. This will not hook up to a PC.
It seems a logical leap for the bright former naval radar technician, Doug Engelbart, to invent the first mouse in the mid 60s...
On the right are some scans of this pre-mouse. A ball mouse, after all, it just a trackball upside down—much smaller than this one.
The label says:

Notice that the trademark symbol is subscript rather than superscript. The O in Orbit encloses a crosshair (+). A rocket tail and rocket off the O complete the logo.
The file name "AIRTRAFC" for the below photo [from MS Office 97 clipart] is its only identifying information. Note the round display screen and the person using a trackball to maneuver (the cursor?). [larger view]
