The adapter is a small simple board and a machined aluminum card carrier which holds the card firmly and slides into the triple high VMEbus in a Sun. It introduces a minimum of delay, on the order of a hundred nanoseconds, in the signals crossing it, so mostly you don't care whether a card is using the adapter or not -- unless you can find a 32-bit data bus version on a VMEbus card (unlikely unless it's very recent). [PS, the bus is called the VMEbus; you don't go around calling them Multi cards now do you?]
