Yet another BBD question...

[Harry Bissell]

Definately worth a go... It might make the clock null schemes (by using
inverted outputs if you are going to do that trick) not work... as the
pulses would no longer line up ???

I thought of this one also but never tried it... (of course in a full bridge
you do it... or die ...eh???)
