HP9845B - Monitor?

I've just been given a HP9845B. But I was told the monitor had long ago been broken and thrown away. There was a brief discussion on the list about this last giant HP desktop calculator/computer back in March and April this year. There is still almost nothing useful I can find on the web about it. The monitor appears to connect to the body by two combined mechanical/electrical connectors, sort of "monitor leg bases", protruding I have to clean it and check it out before trying to apply power, but is there any other way of getting a monitor output from this thing, other than those? The only other thing I have for it is a HPIB connector cable. Any other hints appreciated. I never expected to find one of these, but it was high on my wanted list. I clearly remember going to a presentation by HP at the University I was working at in 1979 or 1980 where one of these was the star attraction, and I still have the brochure for the 9845 from that day. Now for the 9815..25..35 etc! Phil Brisbane, Australia.
