My 11/730 came with a BA11 10.5" expansion box

little card in the Unibus Out slot of the CPU backplane that linked
to the bulkhead with 3 ribbon cables, That took a flat screened cable
with 3 connectors on each end that went to a similar bulkhead on the
expansion rack, then 3 more ribbon cables to the Unibus In slot of
the first backplane in the BA11.
That small 3-connector card for UNIBUS in/out is the same as what is
used on an 11/780, to connect the DW780 to a BA11, FYI.
