I was hoping that was the case :-)
Seems like a lot of 80's display hardware have common ways of failing.

yep - that was exactly the problem - I found that out more by accident than
anything before reading your reply :)
I pulled the case off and just went to tweak the horizontal hold pot to see
what effect it had on the display (to try to track down the fault a bit
further) and the display choked into life as soon as I touched it.

now I just need to make a suitable comms lead, I seem to have lost all of
mine :)
