yes, it seems really weird to see it woring in OS9 but not in system 6 or 7, i suppose i could try loading system 7.5.5 on my classic... i have the maximum 4mb of ram installed, might as well use it for something..

does this version of Vision really need OMS? did OMS even exist in 1989? i'll try installing OMS and see what happens, that would make sense though, since "unimplemented trap" means it was looking for some code which was not available.
