chasing down an old game

Many many years ago in a distant galaxy (called Strathclyde University Computer Science) we ran a game on the PDPs. It was great at testing out terminal line speed handing and debugging curses (well that is what we told the bosses). I remember the game as being called ?search?. But since we had the source code it could have been anything. It was played on 24 x 80 dumb terminals. It was multi user. In the game you moved around the universe in your craft - the display was a kind of 3-D picture (you got closer to a plant and the planet got bigger - try drawing increasing circles on a 24x80!). You could travel through the universe shooting other craft (friend of foe). The only craft name I think I remember is ?shankers? - becuase we had source a lot of the craft names turned into locally relevant names. You could team up with other players and (1 line) communication with a group or with that player. I have searched (on and off) for the game. I cant find anything like it. I would like it to test out the DZ cards on my PDP! - OK that is my excuse ;-) Is anybody aware of what I am talking about? Does anyone have any old code anywhere? Aye, it was not as good as the old GT40 - but it was a different era.
