Agree totally Skip with that deal. Everyone (including the F-Guys) ran two systems BUT with the "potted" units, very rarely (unless
the car was crashed), was the 2nd unit ever needed. Autotronics built some nice stuff for the F-Guys but we paid more for it.
The Teams always played it safe, even with the better design and the potted parts.
In the old days, only a few had complete ignition control. Today everyone is using
the add on systems to get consistent performance pass after pass.

There are a few systems out there with F-1 capabilities. MoteC being one of them. Not Cheap.

Nothing WRONG with a good "Old School Digital System"
