Here's a similar thing. A 4M sram chip is soldered on top, and it
plugs into an EPROM socket, so we can load and test code during
development. One extra pin picks up the uP /WRITE line, so we can
write to the ram, and one other pin lets us pick up +5 or +3.3 for
power.

All that stuff about stress and angles and teardrops is pretty silly,
at least if you do plated-through holes.
