Fanuc A02B-0051-C346 option unit. Built in the days when most of the HMI equipment from Fanuc was built under the Fijitsu Fanuc Ltd banner. This option unit is a precursor to the operator panels that accompanied the Fanuc zero series. Capable of 3 axis and one spindle control with orientation. Likely ran with Fanuc system 3 or system 6 control.
