Craig, I think 5750 and 5870 share the very same pinout, both physically and electrically, right?
I have some NL5870/ZM1332 and their non-standard pin spacing "forced" me to get into the whole PCB design and production process (with KiCad). It turns out that I got more PCBs than Nixies (there was no saving in ordering 3, 5 or 10 pcs!), so when they will show up in my mailbox (and be tested), I will have few spare basic PCBs that I would have offered on the list nevertheless. No problems to share design files for non-commercial use. They are 4-digit multiplexed, 74141 onboard and there is support for both decimal points controlled through NPN darlington. Anode mux'ing is off-board because everyone uses a different method, even myself. It is a very basic design, but I wanted something to hold the tubes not the whole circuit, even though I agree that a PCB is convenient if you're going to build more samples of the same design. The rendering looks like this: https://2.bp.blogspot.com/-Wz75hnLVWvw/WN7RYpV9UyI/AAAAAAAABrI/gUdROEZd2QMsUVcQA9zgEZnGwLmCKAZ1QCLcB/s1600/4xZM1332-01.png So, someone might get to build a 4x 5750 display sometime in the future. My PCBs have been on the road already for 45 days... stay tuned. Paolo -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
