 the design of having to change
backplane wiring for certain cards seems to be rather... ummmm silly

--
this dates back to the days when a DMA interface wouldn't fit into
a single SPC (small peripheral controller) board.
at least they eventually produced G7273 unibus grant jumpers which
aren't little nasty tear-the-back-of-your-hand-off boards like the
G727's are, and have both BR and bus grant jumpers on them. These
were standard in 11/44's, weren't they? so your SPC slots shouldn't
have the bus grant jumpers on them..
