This was the smaller BA23? if so then the slot next to the m7516 is the
bus grant break
and the slot 6 empty is a bus grant break. Notice my margin comments. odd ordering of
slots 4-9 indicate direction of bus grant for Interrupts and DMA.

I Thought on the BA123-bus the first 4 quad slots had an AB/CD
configuration
but I'll try this one.
