[sdiy] Module format

[Paul Schreiber]

If I was going to put effort into this, the logical format would be SIM memory 
module. Reasons as follows:

a) it's a specific, world-wide defacto standard

b) sockets are cheap and available world-wide

c) there is no specific "extension" height above the 2 "prong catch holes" on 
the ends, so you can fudge a bit on overall pcb area. I'm not sure if there is a 
de facto spacing connector-to-connector for the angled versions.

d) other companies have products on this form factor, such as:

http://www.systronix.com/tini/tini_simm.htm  (this is larger than I imagine, but 
you get the idea)

http://www.imsys.se/products/modules/snapmodule.htm (another "double-wide" size)

I'd use the old (1990s) SIMM size (ahh...the days of spending $1200 for 4MB of 
RAM).
