I know the Williams ROM boards (Joust, Robotron, etc.) had a couple of
jumpers to switch between 2732s and 2532s. I would assume you can do
the same type of mod manually to your Space Duel board. See the
following docs for more info (jumpers W1, W2, W3, and W4):
(page 9, top middle looks like jumpers connect between A11 on the
address bus and pins 18 & 21 on the sockets)
