Silicon Graphics Multibus "IP2" board

Recently I began fiddling with an old mc68000 based "Callan" system and that got me digging through a drawer of old multibus boards. "Old" goes without saying I guess. My digging turned up this "IP2" board which has an mc68020 chip on board, which makes it the snazziest multibus board I have.
