I was originally thinking twisted pair ribbon cable
until I saw what
100' spool of that would run and decided to try just the straight
"grey" ribbon cable for now.
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 probably will not be making a production run of
these boards unless I
get a *lot* of interest (100 boards or so). If you want some, let me
know
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).
