I've got two small monochrome CRT modules. They've got an unlabeled connection but from comparing with some other connectors I'm pretty sure it's just:Voltage/ground/video/H sync/V sync

Voltage/ground/video/H sync/V syncSo my question is, what's the easiest way to drive this? Like, some way I can make a raspi or VGA video card drive these?

It's something like this:
An open frame CRT module for use inside a portable computer. -

@foone It depends on the video mode it expects. A VGA card should probably be able to drive it, but if it wants composite video style timing (525 or 625 lines), you'll probably need a sync separator and a composite source.
edit: I think there's a way to hook a Pi up to generate VGA using an R2R DAC, but it's been ages since I looked. It has a parallel output too, on the GPIOs, it's meant for LCDs. I have no idea how to set the mode timing though.

I don't have any specs for what resolutions/rates it needs, though. So something that can flexibly try a bunch of different options would be handy

okay I found a manual for a protocol analyzer that uses the same model of CRT, which has some technical details:
So it's 16.66 KHz horizontal refresh, ~60hz vertical, and it uses a 5V signal for the video.
