WTD: cable Digital VR 260 Terminal
WTD: cable Digital VR 260 Terminal If you have one for sale contact me off list vintagecomputer.net/contact.cfm
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. -Dave -- Dave McGuire, AK4HZ New Kensington, PA On September 8, 2016 12:26:42 PM william degnan via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

Ah, like a 3-post co-ax color display I get it, thanks. Monochrome = one post. 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. Were these on par with things like the PS/2 monochrome VGA display, I am guessing the VR260 was not a graphics terminal, but I will learn soon enough. Here is a pic http://vintagecomputer.net/digital/VR-260/ Anyone use this display, like it? Worth using? Bill

Yes, it's composite video, but not NTSC. (far higher resolution than NTSC)

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.

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.

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.

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. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
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?

Yes. The end of the cable has a block of plastic molded onto it, with a screw sticking through it with a big finger handle on the end of the screw. You hold the block against the back of the monitor and tighten the screw to pull the block against it. A small pigtail cable, 2-3" long with a BNC on the end, comes out of the end of the block to connect to the adjacent BNC connector on the monitor. In most of the variants of these cables, on the top of that plastic block is also an RJ-22 connector (telephone handset connector) for an LK-series keyboard, and a MicroDIN connector for a DEC-protocol mouse. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

ok I did think that this might be the case, but the manual does not mention a keyboard so I became unsure if this was a terminal or display, or something special purpose. b

Well the keyboard and mouse just plug onto the cable, not to the monitor...the monitor is just a regular dumb analog video monitor, nothing more. The DA15 connector on the other end of the cable also (obviously) carries the keyboard/mouse signals, but they are separate from the video. That cable can be very long, I've seen them at 75 feet, so that the "workstation" kbd/mouse/CRT end can be in an office while the machine it's connected to can be in a datacenter down the hall or whatever, with just one cable. (aside from power for the monitor of course) But there are different cables, depending on what type of system you're planning to connect it to, just beware of that. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
