I really love the idea of small "rapid development" boards that allow 
the beginner to have excellent functionality with minimal effort.  
While we "geeks" like to know, and touch the hardware (i.e. ASM 
programmers), I think that the most innovative use of these devices 
will come from the ability to use them at a higher, more symbolic, 
level.

I applaud your efforts.

I have been considering making a breadboard-able board for the 
ATmega128 which essentially has all the JTAG/ISP, and support 
hardware including FRAM and battery-backed precision clock on one 
large "stamp".  You supply the *regulated* power and get all the 
ports along the edge of the 56 pin "DIP".  PortG (5 pins) is brought 
out on a separate header.

The problem is that the minimum width (in a 2 layer design) is only 
0.1" less that the usual width of a breadboard.  So, you can not 
easily breadboard the "DIP".  If you have 2 standard width 
breadboards with a power bus between them, then you can span the 
boards with the DIP and then have MANY available pins to prototype 
your stuff.

I suppose that I could go narrower if I were to use a 4 layer design, 
but I could not afford protoyype boards for testing!
