It is a Multibus card which sites on a Multibus/VMEbus adapter.  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?]
