I'm having a heck of a time figuring out how to use the CA and CB ports on
the 6522 as inputs. From the documentation I have, it seems the CA port
can be used for one TTL input, and CB can be used as two.
But how do you set them up as such? The documentation is confusing.
I'll sleep on it and see if either a) I wake up refreshed and figure it
out or b) wake up and find a nice helpful message waiting here ;)
