  That should be fine; the DEC M9042 board (basically equivalent) used three
  H854 flat cables, see:

    http://www.computerhistory.org/collections/catalog/XD149.80

  The DEC board makes every other conductor in the flat cable a ground; not
quite as good as twisted pair, but close.

  I would definitely be interested in some (how many exactly would depend on
the price).

Looks like the ribbon cables there are foam-separated-and-bundled, rather
like a BC11 cables.  What are folks using for foam-replacement when they
rehabilitate existing BC11 cables?

I also would be interested in some (how many pairs exactly would depend on
the price, for me as well).
