well, I will probably use oshpark to make a classic REX pcb, and see
how well it goes. I already have the "large diameter pin holes" which
yes this board could use. I could post the diameter I use. It is a
lot faster to just trim the panelization tabs than to grind the whole
thing.

The cad files are right up there on oshpark.
I did have to sand down the edges a little because the "rat bites" landed
right in the middle of the edges, which screws up 2 half-holes on each
side. You can see it on 2 of the pictures of the bare new boards before
sanding. Just zoom in.
As for space
As a matter of fact I was thinking about making a RAM ExtRam clone (poor man's
REX ;-) and was wondering the same thing, how to avoid having to shear/grind
the edges.
How'd he do that?

well that's very interesting; I had assumed that since my layout tool
would fail the design if I put the board edge down the middle of the
vias, that no one would build with that error. So, I hand grind REX.

hey, cool. didnt you get a board violation for putting the board
perimeter in the middle of the via?
do you need a spacer under the board when in the socket?
