Nope, it's not a production thing. Adding more hardware means finding mo= re=20 board space (yes, it's tight), and there's no challenge in that :-) > How about having a single transistor or something connected between the > common DP line, the common pin for the digit on which you want the DP > lit, and Vcc...

Yep, see my original post -- I figured out this solution for this particu= lar=20 app, but would like to solve this problem for possible future use.
