Yeah, but I think those are multipliers, not dividers.


So then, what shall we call it. PICDIV draws from the PIC.  Next thing 
from TAPR,  catering to the retropunk style, will be a TUBEDIV or EJDIV 
(Eccles-Jordan homage) - what better to drive your nixie (or stacked 
neon bulb) display than a 19" rack full of modules.

I'm sure if one looks at pictures from WW 2 era, there's plenty of this 
around.

If I didn't have many other projects going, that might be a cool one. 
Lots of folks have binary clocks on their desks at work, but they're LED 
and solid state.  A few have Nixie clocks, but solid state driven.
