I found this video of the Agilent 54621A earlier, interesting the front panel boards got changed to FR4, also note the comms modules from older HP 546xx scopes are not compatible (different connector) and may cause damage if forced on & used like that, you have been warned.

"Buried halo" reminds me: when is Netflix releasing the next season of "Warrior Nun", which ought to be called "Ninja Nuns With Guns"? It is good mindless entertainment late at night, with a drink, reading this thread on a tablet.

Still "Agilent - Yuckyputz!"  :-DD, 54622D is the 100MHz version, of the 54621D (60MHz) that Mnem is trying to figure out the monitor connections for. Seems to have different knobs fitted.  :-//
Any chance you took some teardown pictures? We seem to be lacking detailed pictures of the CRT boards, the youtube videos don't show them in any detail and focus too much on the scope mainboard.
