Hmm, haven't seen the "2 outputs" version, I'm used to just going back to 0, 1, 2... after hitting ten on the inputs. There are some good scans of the old data sheets, including the expected behaviour of both 7441 and 74141 chips, along with their internal logic diagrams on Dieter's Nixie Driver Tester Project page: http://www.tube-tester.com/sites/nixie/74141-NDT/74141-NDT.htm - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
