There were some requests a few months ago for Eurocard size.  Since the size
I was contemplating was close, I figured there was nothing to loose making
it exactly that size.  I also wanted two rows of .1" pads for putting
various 1x or 2x .1" connectors on the board, so making it mechanically fit
a Eurocard type B was also no big deal.  Otherwise I wasn't convinced that
the Eurocard thing was going to make any real difference in sales volume, so
I didn't want to burden the board with Eurocard issues to the point of
detracting from the main stream use or making it more expensive.  I thought
about putting all the external connectors on the left edge, but that just
didn't work out.  I would have had to drop some features and/or decrease the
prototype area.  I thought that would hurt sales more than the Eurocard
thing would help it.  I guess there's not easy way to know whether that was
the right decision or not.
