DEC UNI/Q-BUS board physical size?

I would have thought the Bus Handbook would show that, but it doesn't contain a formal mechanical spec. It does show (on page 90 in Al's copy in dec/pdp11) show the overall dimensions of a M9202 Unibus Jumper module. That's a dual wide module and it seems to be full height. (At least the height matches that of the UDA50 shown in the UDA50 engineering drawings). What isn't shown, unfortunately, is the details of the edge connector. The UDA50 (hex module) is 8.41 by 15.688 inches board dimension. As for the Q-bus, those are dual or quad, not hex, but I think that the mechanical specs are identical to those of the Unibus. Ok, the RQDX3 board is 8.41 high by 5.187 inches wide, same within a few hundreds as the M9202, so that suggests the mechanicals are indeed the same. paul
