Single-height Qbus grant continuity PCB

[Tony Duell]

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?
