Actually, just to clarify: yes for the black box, no for a distributor.
Vacuum advance for distributors is "port vacuum"-- otherwise, you'd have full advance at idle. The black box takes manifold vacuum.

Exactly. For distributors there are specific ports on the carb that sit just-so with respect to the throttle plate. Just above but not too far above the throttle plate. No advance(vacuum) at idle, or large throttle opening, but some at slight throttle: just off idle and cruising only.

Manifold vacuum can be used electronically to make a curve for ALL throttle positions.
