All the PDP11 people here will know the little square grant continuity board used in Unibus machines, along with the later dual-height one that also connected the NPG signal. And the common Qbus grant continuity board that was also a full dual-height one that had a couple of pairs of pins linked on one of the connectors.
But I have here a little square board (the same size as the older Unibus grant continuity card) with just 2 pairs of pins linked. In the etch is a Digital logo (so I assume it's a real DEC product) and : LSI11 Grant Continuity G7272 5012564B Side 2 Has anyone come across that one before? -tony
