Siemens DL3416 Here you go: https://www.youtube.com/watch?v=SIkGyWIuCIo Looks like they may have the decoder built into them. And 16-segment as mike says. =============== Yup, that's what they are, similar to the DL1416s used in the AIM65 and elsewhere. A little more intelligent than just decoders & drivers; send it a 2 bit address and a 7 bit character and it'll store and display it (them) until cleared or replaced, easily cascaded for longer length. m
