The Burroughs SD-11 sphericular display has historically been a pretty mysterious device... it has incandescent bulbs and looks like a projection display, but produces numbers using a dramatically different system. Normally SD-11s are glued shut and can't be dissembled, but I had a damaged one so I sacrificed it to the screwdriver gods and took lots of pictures explaining how this very strange device works. Enjoy!

I don't think a laser printer with transparency paper will work for a sphericular display like it does for projection displays; the one I cut apart above has about 4500 tiny circles printed in a 1 inch square. One would need a very high resolution printer and good transparency film to pull that off... -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
