Very nice. Microcore, driver and mux all in 2 chips...impressive.

Why don't you put all your stuff on your web page. If you don't I'll have to!
I'm just finished breadboarding and testing the NuRing circuit and am moving on
to the N/2 soon. Your creating them faster than I can try them!

Arggg. Of course.
