[sdiy] Module format

[laxt57 at aol.com]

Hi 
So we have a preliminary spec on the bus.
What for the first module? Maybe a vco core?
Is a asm-1 style vco in thru-hole possible on
a simm stick form factor?
 If memory serves does not the bergfotron squeeze
4 asm-1 vcos on a 100mmx160mm pcb?

Swap +5 and Dgnd to pins 1-2 and move everything down...
this will allow you to skip these more easily, and keep them at
the outer edge of the module is used... farther away from all
the 'good' signals   :^P
