What I want to know about is like how many columns of how many pins at
what spacing, like how IDE is 20 columns of 2 rows of however many
pins.  If there is some standard connector that would be appropriate
for connecting daughter cards, we should use that.  But what we use
should also look like rows of headers, kinda like how the IDE pins
look.
