If you set the Zuiko to its smallest aperture, it maybe behaves in the same
way as a PF lens. When using a Zuiko with the OM-2SP or OM-40 you have to
choose the smallest aperture value, too (the same with the Yashica 109 MP).
Then I think, that the OM-2SP or OM-40 choose an aperture value but then
add the best possible exposure time via ADM. Maybe the OM-101 use also ADM
(TTL-flash is possible) and therefore it might be possible to use a stopped
down Zuiko in the same way, but I haven't tried it, because I don't want to
modify a Zuiko mount.
