Metaphor Computer Systems

While working as a computer tech around 89-90 I was asked to install 2-3 of the damnedest things I'd ever seen. They were called Metaphors, and what was so cool about them was the front panel flipped down under the screen and out slide a wireless keyboard, wireless mouse and a keypad. They were GUI based, though for some reason I remember them being green on black or perhaps white on black monochrome screens. I set them up and someone else came in to connect them to a Metaphor server - apparently they needed their own proprietary server. So needless to say, while putting some stuff away in my office, I had some of my old notebooks from way back when and while fingering through the pages I notice - Amex - Metaphor install and remembered these funky little units - very slim and high tech for their time I have to say. Anybody own an actual unit and have some photo's? Curt
