      Jan, et al -
      In response to your earlier message, I purchased some of the new smartsockets. I located a source for suitable pins for the ZM1350 that I'm using, and got those soldered in.

      I was hoping that the documentation in the files area on this group would apply, but apparently, the boards I have are a respin and the reference designators appear to have changed. Where can I find an up-to-date schematic and assembly drawing for these new boards? I checked your (Jan's) website, and eventually the links led to this discussion group. I'm capable of reverse-engineering the PCB and figuring it out myself, but that's a real hassle that I'd like to avoid.

      I would also be interested in the voltage and current levels others are using to drive the ZM1350 tube in a non-multiplexed configuration. I've been trying different levels of both current and voltage, and the tubes I have tried can't light up the length of any segment completely without bleeding and generally looking like a poisoned tube. I've only tried 2 of the 10 I've purchased, just in case there's something I've done to wreck them. I'm pretty savvy about electronics, but I don't have a lot of specific experience with nixie tubes. I'd really like to get these ZM1350 tubes working, though. I'm powering them with a neonixie supply that is adjustable from about 135-190vdc, and I haven't taken it over about 160.

      Thanks in advance.

        The cathode resistor values were selected for a voltage of 170V and with a wire link fitted in place of an anode resistor.For that reason your starting point should be a voltage of 170V and no anode resistor.

        I have had a couple of zm1350's which behaved similarly to yours, and I ran them at about 25% over voltage for an hour which seemed to wake them up

                  I'll check that again, but I have to run off to work just now. Over the weekend, I went ahead and traced out the board and compared it to schematics I could find. I matched up the resistor values to each segment and mapped that onto my boards. I was unable to determine a definitive reference designator for some of the resistors, but I was able to make sure each segment had the correct value based on older schematics. I'm waiting on the switching transistors to arrive, and when those come, I'll try to fire these up. I also need to figure out how to daisy chain these, since the config is updated from the schematics I've seen so far. Thanks all for the help. I'll try to post results when I get these puppies running.

                    in fact I check them all on the original factory tester and many many
                    have flawless lightup but at slightly higher voltages, they seem to
                    be quite prone to "in the shelf cathode poisoning".
                    I do not sell any that do not light all segments properly or even
                    miss segments.
                    With slight overvoltage they will recover easily.

                      The PCB's are my design.
                      And Jan has put all of the documentation on line.
                      There's a partlist, with resistor number and value.
                      Also the board has numbers with all components. (One or two may be hard to
                      read)
                      But to help that, there's a PDF with all components marked as well.

                      Be carefull with T7, the component outline is wrong. (E and C must be changed)
                      Look where the Emitter is located.

                      Interconnection is also simple. Just connect the adjecent sides 1 to 1.
                      Pin 12 to the processor is the data input for the string.

                        Hi, Jan -
                        Yeah, I exchanged messages with you and you mentioned "over-" something, and I forgot if it was current or voltage, and was unsure about how much. I don't know if the power supplies I'm using will go as much as 25% over-voltage (212v), but they may approach that.

                        I read a rather detailed web page about testing of the ZM1350 tubes, and I'm pretty sure it was one of your pages. You documented the effects of various "error" conditions, for example, what too little or too much voltage did to the display's appearance. Similarly, how to see when you have enough (but not too much) current. It was a very informative discussion, but when I tried to find it again, I couldn't. (sometimes I get too absorbed in the reading, and forget to set a bookmark) There were also links to a couple of videos showing the "dancing segments" test on a good display, and the visually interesting "dancing segments" that resulted from a badly poisoned display. It was the kind of thing that looks really cool, but is probably very difficult to reproduce. I'd like to find that page again.

                        I may have mentioned that I'm a product of the age of transistors and IC's. I don't know how hard or easy it is to "kill" a ZM1350, but I'd rather not perform any destructive testing. If I have to burn them in for a while at elevated voltage, that's fine, I just don't want to cause damage.

                        I'm going to be running these displays unmultiplexed because it's said to be easier on the displays. You don't have to drive them as hard if they're always on, and you don't have the mechanical stress of switching. (Apparently, the segments can make noise if switched hard at audio frequencies.)

                        Well, I'm off to try to find code to emulate something like a FLW/clock. Thanks for the help, folks.

                          Doh! That schematic isn't up to date. That schematic shows J1 with 5 pins. I don't have a board with me to compare reference designators, but my boards have J1 and J2, each of which has 4 pins, rather than 5. I've figured out where to wire the power supplies, but not which pins are "data in" versus "data out." I suppose I can find out via experimentation.

                          Aside from the documentation, I like these Smartsockets. There was obviously a bit of thought that went into the design, and they're nice and compact. I dismantled an old 68030 PGA socket (remember those?) and used the pins for my ZM1350s. They're a nice snug fit on the pins, and they work well in the Smartsocket. Note: if anyone else tries this approach, make sure that the pins will fit the ZM1350 BEFORE going to all the trouble. I have more than one of these sockets, and not all of them will accept the pins of the ZM1350.

                          Anyway, before I trash up the forum with asked-and-answered questions, I'm off to troll about the archives. Thanks for the help.

                              > Yeah, I exchanged messages with you and you mentioned "over-" something, and I forgot if it was current or voltage, and was unsure about how much. I don't know if the power supplies I'm using will go as much as 25% over-voltage (212v), but they may approach that.

You documented the effects of various "error" conditions, for example, what too little or too much voltage did to the display's appearance. Similarly, how to see when you have enough (but not too much) current. It was a very informative discussion, but when I tried to find it again, I couldn't. (sometimes I get too absorbed in the reading, and forget to set a bookmark) There were also
                              links to a couple of videos showing the "dancing segments" test on a
                              good display, and the visually interesting "dancing segments" that
                              resulted from a badly poisoned display. It was the kind of thing
                              that looks really cool, but is probably very difficult to reproduce.
                              I'd like to find that page again.


                              if it was mine it´s www.askjanfirst.com/zm1350.htm

                              in for a while at elevated voltage, that's fine,
                              I just don't want to cause damage.

                              its far easier to destroy if you drop it from the table ;-))

                              because it's said to be easier on the displays.
                              You don't have to drive them as hard if they're always on,
                              and you don't have the mechanical stress of switching.
                              (Apparently, the segments can make noise if switched
                              hard at audio frequencies.)

                              this is far more of concern with usual nixies as their electrodes are
                              hanging free.
                              The ZM1350 electrodes are tied to the bootom plate of the tube and
                              should be quiet.

                              there is some stuff in the neonixie-L- archives
