   The 306/307s also have built in BCD decoders. I've been trying to find a data sheet on the 311 so that I can see what the difference is between it and the 306/307.

     306's or 307s will work equally well. The one difference between them is that one has the decimal point to the left of the digit and the other has the dp on the right. My unit doesn't use the decimal points so either display will work fine.

    It's possible but all the leads on them are weak and I'd probably have to eventually replace ALL the leads.
