Got a really nice Medelec display in the list for Xmas teardown. GE CRT's in there, and i just tried powering this up and it still works, though with one having a P37 ultra slow phosphor, and the other CRT being a flat face brilliant white fast tube, designed to be used as a photo printer onto some self developing paper ( Weird stuff, looks like regular thermal paper, but responds to bright light by darkening, though as it is now around 30 years old it really is poor contrast now, but does respond to the blue laser pointer quite quickly) as a semi permanent recording method. was some physiological recorder, but all i have left is the CRT display section, that has a 4 channel display, and some assorted controls for the 4 chopped traces.
Still got to see if I can get the Domino A200 printer in some sort of running mode, or at least get the passcode for the service or maintenance menus, or even any manual.
