I imagine that Multibus II <-> VME compatibility would require a little more work than just buying a converter. Multibus II is not a normal bus. For one thing, a Multibus II board expects the backplane to have a thing called a Central Services Module to handle some system configuration issues. For another, Multibus II implements a rather complex message-passing protocol, in addition to normal master-mode and slave-mode cycles. If all you want is to talk to VME using the latter, a converter might be all you need. On the other hand, if you want to convert the message-passing protocol into VME cycles (or vice versa), I'll bet you'll have to rewrite some firmware on either your Multibus board or your converter.
