    The service manual says they were made for an F55 video terminal. 1980s video terminals had video driver boards in them to convert the TTY signals to video. That driver board varied wildly on the output signals, some would output composite video leaving the monitor to control the raster scan, sync, horizontal & vertical sweeps but some would output all of that and there would be minimal circuits in the monitor cage. Hopefully you have ones that take composite video. can you get pictures of the back and sides?

    Also, as others have said BE CAREFUL! the crt itself is actually a really big capacitor that can store a lot of potential and deliver a high voltage zap long after it is unplugged. While it’s running the fly back circuit produces 1KV (1000 volts) or more so I say again BE CAREFUL.
