Sure about which bit? I'm reasonably sure that the BA123 (old style
world box most often used for the MicroVAX II) is four slots of
Q22-CD and then serpentine Q22-Q22. I'm fairly sure the BA23 (smaller
box, same size as the Rainbow) has one less Q22-CD slot (hence it has
3).
I'm sure that the BA200 series boxes are all Q22-CD, and the BA200
Series Module Design Guide agrees with me there. In fact, I think
you were agreeing with me too, unless you meant BA123 where you typed
BA215.
