The M9047 grant continuity card was dual width card which plugged into an unused slot in a QBUS backplane, and carried the bus grant line signals from the 'in' pins to the 'out' pins in the slot.
It carried not only the DMA grant line DMG, but also the interrupt grant line (IAK, on pins BIAKI - pin AM2 - and BIAKO - pin AN2).
