One major difference is that the 6845 has mostly write-only registers, while many can be read on the 6545. So using a 6845 instead of a 6545 is some sort of downgrade that might cause trouble. But since it worked on one PET, it should also work on the other. Maybe some software titles won't work properly anymore, but that's about all there is to expect.
