earliest graphics display system in your collection?

Richard wrote: OK, related question - what's the most interesting graphics display system that anyone has in their collection? Either interesting due to concepts used, or interesting due to the spec considering the age of the device etc. For instance, some of the late 80's / early 90's hardware from the likes of SGI are pretty impressive in abilities and architecture - using concepts that have only hit the mainstream in the last few years - but of course they're by no means 'earliest'... I wish I was at Bletchley right now so that I could get some specs on the Bell and Howell / de Graffe video presentation system that we were given a while back (and that I mentioned on this list). It's all totally bespoke hardware for doing video work, with a user interface that for some reason reminds me of early versions of Deluxe Paint on the Amiga. No less than 8 processors in it - seven of those are custom and dedicated to graphics processing work, the other being a lowly Z80 for housekeeping. All from a mid-1980's system. Oh, and it's the only machine I've seen that uses rock in the construction - for stability, the base of the main module is solid granite :-) (cost was IIRC 20 thousand pounds in the mid-80's, so I suppose they could justify blowing a bit extra on frills like that...) cheers Jules
