The same seller has 2 more here, with more pictures: http://www.ebay.com/itm/321346505250

There are some discrepancies in the descriptions ("New" vs. "used, but good condition", etc.) I would confirm with the seller that you are getting a functional unit with all of the information needed to light it up and communicate with it.

Radar up to fairly recently was displayed on a CRT. I would guess like
everything else they now use a computer flat screen monitor.

A CRT allowed a lot of the Math needed for the radar display to be
actually done by analog means in the tube itself. Radar CRTS typically
have P7 Phosphor.

I remember finding a website years ago, kind of a russian old electronic enthusiast / museum site, that had details on this display (or one very similar). It has a smaller sibling - bit like a 20x100 size, that cropped up on ebay quite often. It has nothing to do with radar, it is a neon based pixel display. The native panels, like shown in the second listing posted above, are a nightmare to drive iirc and use glow transfer to shift data along the rows. If that first listing includes a controller board with RAM and scanning circuits then its a nice display! For that money though, you would probably be better off getting an old panaplex / pinball machine display? Unless you like a challenge...
