Well, I considered all of these ideas, and Dwayne's was the neatest fit into my
requirements (customer already uses 4013's).  I built it, and it works like a
charm! Dwayne is saying, 'of course it did, goof'.  Dwayne goes to the top of
my Christmas card list.

I like Bob's transistor solution too.  If I were a bit daring (IE persuade the
customer that it really does work) I might jump on it.

Thanks very much all!
