I am trying to build the IC 555 Based Message Display Circuit my problem is Multisim 13 does not have a KLA 511 I have tried using the
15 Segment – LED Alpha Numeric Display (Based on A-398G) but when I run the simulation All I get is error. It seem to me the one that I’m using is not right. I have looked on the Internet for a replacement one but can’t find any. If any one can help me with this I’ll appreciate it very much. I’m trying to build my grandsons name for his room.
