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 _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
