Re: [neonixie-l] Help with clock identification..
Definetly home brewed. Great point to point wiring. The voltage regulator is 6944 = 44th week 1969. So early TTL stuff. I built one myself but found that AC voltage transients (vacuum cleaner was especially bad !) kept disrupting the correct time. Taylordan has a similar design of TTL logic with nixie readouts. Hope you get it up again. I'm always on the lookout for these early home-mades and have quite a few.

Hi Guys, Was here under my old ID of Orange_Glow_Fan but somehow (old age!) forgot my ID/Password and the email address it was associated with so here I am under a new ID... I picked up this old clock and wondered if anyone had an idea what it is.. Looks hand made, I think, at least hand wired. Pretty nice work. The display is made up of incandescent bulbs (CM344, 10 volt, 14ma) All ics, no micro. I also need help figuring out how to fix the segment 'mask' as you can see it's pretty well toasted! The clock seems to work as far as I can tell, but there only a few bulbs still working so I can't be positive it's fully functional. Finding the bulbs is going to be a real challenge. At least at a price I can justify spending..! Kerry -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

[neonixie-l] Sperry panaplex SP-151
I bought 3 of these at the last dayton hamvention !. I sold one on e-Bay but still have 2 left. One is the bare device, the other was soldered to a self-made breakout board, I got $30 plus shipping to USA for the one I sold. e-mail me at ( alb at sympatico dot ca ) if want one of them - Original Message - From: gregebert To: neonixie-l@googlegroups.com Sent: Friday, November 28, 2014 6:20 PM Subject: Re: [neonixie-l] Nice quiet month... That's a really nice panaplex - what model is it? It's a Sperry SP-151. Obviously it was intended to be used for clocks (AM, PM colon, tens-hours digit is only '1'). I havn't seen any of then in-use, so I wonder how many were built. The unit I have was a sample my father received from Sperry; he used to design cockpit displays. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

Re: [neonixie-l] Re: Just got 80 new Burroughs PIXIE B-9012 tubes, if any interest

Unlike Nixies, more than one digit can be on at the same time (if cathode resistors are used, rather than a common anode resistor). They need only +150VDC, and very little current. The digit is small, but the appearance is very interesting, like a Dekatron, but with digits rather than dots. I don't ever recall seeing them used in any commercial gear, but presumably they did appear someplace, maybe another list member has that info. They can be used as status displays to show up to 10 data items at the same time. They can almost be used as a single tube for hours as well, because two digits can be on at one time (1+0 to show 10, but NOT 1+1 to show 11, 1+2 to show 12, for example), a novel and more "clock-face-like" appearance, but not really ideal. The base is a non-standard 13 pin (3 center pins, outer circle of 10), so I have no hope for sockets, but clearly loose pins will work fine to a PCB. Because the numbers appear to race around the outer diameter of the tube when cycled, they would provide very attractive seconds/minutes displays in clocks. Driving is dead simple, ground the cathode to light, just as with regular Nixies, but less current is required (larger resistor). Because more than one can be on at a time, fading is possible to enhance motion. There are also simliar tubes from Philips in europe, but their drive is quite complex, and they are not interchangeable with these. Anyway, I will have them posted up to Sphere Research shortly, or you can just email me for more details. I have the factory data sheet as well, and I will email the PDF to anybody interested. They will be quite cheap, but there's only this one single batch available, no more stock after this, and frankly I was surprised to get these. The appearance of this batch is excellent. all the best, walter ( walter2 -at- sphere.bc.ca ) sphere research corp.

[neonixie-l] Nixie calculator with core plane memory
I have a Wang Engineering calculator about 1968 with desktop keyboard and Nixie display with electronics in a small suitcase which sat under the desk and a printer which did spark-erosion on aluminized paper. Core plane memory allows a program to be halted at the end of the work day when the system is powered off. Next day when you turn it back on, a lamp illuminates to indicate that it is still running the program ! No instant results when you hit execute back then.

Reference in the text to the "recirculation loop" leaves no doubt. I'm curious to know if anyone has ever seen a Nixie instrument with a core memory? Presumably they must have existed sometime, somewhere, but I would have thought the cost - together with the "recirculation loop" and write electronics - would be substantially more than a few BCD to decimal decoders, even in the days before TTL. I do recall, however, that one of the Anita nixie calculators had a magnetic memory - a torsion delay line. It was kind of like a clock spring made out of stiff wire. An actuator would twist it at one end and the torsion wave would go round all the coils and appear at the other end some milliseconds later, where it was sensed and fed back to the beginning. So you could store data in it, like a very fast tape loop. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
