Talking of Olivetti machines, has anyone else ever come across the Olivetti M10? It's a laptop with a flip-up display (It doesn't open like a normal modern laptop - the upper face of the display when closed is the face where the image appears, but you can flip it up to a more convenient angle to use it), and appears to be related to the Tandy M100. The keyboard has 1 fewer key (I think it's either Graph or Code that's missing) than the M100, and has a different layout. The main PCB is different in layout to either of the M100 PCBs, but is electrically very similar (even down to component designations being the same). The built-in software is very similar (identical? apart from obvious changes to support the different keyboard and to say 'Olivetti' in start-up messages). -- -tony ard12(a)eng.cam.ac.uk The gates in my computer are AND,OR and NOT, not Bill
