I have an old Nixie tube desktop calculator somewhere, it uses diodes as the active calculating elements. DCL they called it I think. Wow. It's got some 6 digit precision if I remember correctly. I can see a blue glow inside some of the Nixie tubes, I am sure those tubes generate IR, X-ray and all sorts of other stuff that makes the mice die around the house... bye, Said ************************************** Get a sneak peek of the all-new AOL at http://discover.aol.com/memed/aolcom30tour

DCL they called it I think. Wow. It's got some > 6 digit precision if I remember correctly. Wow! I have a drum-machine with a sequencer operating that way, but no counter. Having seen Zuse Z3 in action brings you perspective. :) 22 bit floating point in relays. :) Let's see if we can't get something similar out of DCL. Now where's that bag of 1N4148 I bought a few years back! :) > I can see a blue glow inside some of the Nixie tubes, I am sure those tubes > generate IR, X-ray and all sorts of other stuff that makes the mice die around > the house... IR yes - some, bring your palm up and feel the heat. But the tubes inside is better at it. X-ray - no much really. Too low voltage (150 V?) to really become a hazard. Those TV-tubes you smashed as a kid was running as high as 25 kV and that is the normal limit, but the thick glas is there for a reason. If the mice dies around the house, suspect the neighbor cat of not doing its job propperly, if they only disappear be happy about him or her not being THAT lazy. :) Cheers, Magnus

There may be a slight amount of IR from neon however. Bruce
