The unit has a multifunction controller and display. The display displays time in 24hours and GMT by selection. Time is set thru switch input. The display displays frequency for the PTO and BFO. The connections are very similiar to that used by AADE — look at. Google AADE or look at the S-Line schematic for HFO, BFO, PTO connections – any Collins tech can make the connections. I have been told that a Collins engineer designed the unit. The unit includes a Water Universal Hybrid (WUH) interface for both telephone and recording connection. The schematic for the WUH is included. The unit includes a rotator controller for T2X , Ham M and other rotators. The schematic for the rotator controller is included. The unit appears to be well designed and was probably a pre 312B5 replacement design prototype? Someone spent a lot of time on the design and silkscreen of the text on the multifunction controller. I added the following. I connected the PTO and BFO to the unit from a 75S1. The Kilohertz display came alive. Power supply built in it!
