A: There are jumpers or solder pads to set with either upgrade.
B: A third option existed, a plug in board using the two white sockets.
(Hard to find, I have/had 2 and few other people have seen any.)
The easiest is to swap in 2 of the 4 chips from a upgraded CoCo 3 and
set the jumpers/solder pads.
