Correct, but not in the first few slots that are marked Q/CD. Only in slots
that are marked Q/Q.

It depends. :) The bus zig-zags. On the BA123 it leaves the last Q/CD
slot, then goes to the next slot at the top, then to the bottom, then to the
next slot to the left on the *bottom*, then to the top, then to the next slot
to the left on the *top*, then to the bottom, and so on. So you may or may
not need a grant continuity card, depending on where you're putting things.
It's been nine years since I've looked inside a BA23 so I can't help you
