thanks. I updated the pic of the rear of the display. I point to the connector "holder" - can you confirm that the small hole is just a peg hole to hold the cable in place, so that there is no strain on the co-ax connection?

The VR260 is a monitor, not a terminal, and the required cable will depend on what you need to connect it to. I have spares of nearly all of them and can "hook you up", as the cool kids say.
Ah, like a 3-post co-ax color display I get it, thanks. Monochrome = one post.
Yes, it's composite video, but not NTSC. (far higher resolution than NTSC)
I have adapters that convert various displays of this era. I can also try using one of three color cable connectors, perhaps in some cases one of the three leads will suffice. I don't know what I will attach it to, maybe a DEC 5000 or something with a display port and keyboard port that are separated.
I don't know if something that recent will drive it at the right sync rates, but you'll find out quickly enough if it doesn't. ;)
Let me know what cables you need when the time comes; it's likely I've got it.
Were these on par with things like the PS/2 monochrome VGA display,
Significantly higher-end than that. The framebuffers it was designed to work with drive it at 1024x864. It was commonly used in 1-bit displays, but 8-bit grayscale was doable also.
I am guessing the VR260 was not a graphics terminal, but I will learn soon enough.
Oh they're very much for graphical use. They were used for bitmapped graphics displays on VAX workstations, targeted at CAD applications, but frequently used for regular GUIfied workstation tasks as well.

Anyone use this display, like it? Worth using?
I sat in front of one for years, on a VAXstation-II/GPX, running in grayscale mode. It was one of the sharpest displays I've ever used.
