I managed to pick one of these up a few years ago, but only got the adaptor cable today

Well, it works fine at 1024x768@70 which is good enough for me

The only problem is that the geometry's knackered, as in it falls off the RHS, and it's all trapezoidal. I heard that there's some adjustment screws inside but I can't find them. Anyone got any idea?

It's from 1989 so I'm looking at people like Gaffer and Katie (not being nasty about age here )
