I am using a Stamp to drive the binary pins on a 74141, I have the 74141 powered with +5V, and ground. I know my code is good (tested with LEDs, all checks out, the binary adds up and is timed perfectly.
Something is not working. I have the HV coming from a Tayloredge HVPS, with a 15k on the anode. I have tried four different 74141 (both American, and Russian) Nada. I watched long enough, and the 6 will light up, but nothing else. It lights when it is supposed to, in sequence, but nothing else. I have tried four tubes as well.
the notch at the top of the 74141 is between pins ONE, and SIXTEEN right? What am I missing here?
Thanks
Shane
