The 68-pin connector on these is NOT standard, and definitely NOT
You can use either a BC09J-xx or a BC56H-xx cable. The -xx at the end
specifies the cable length (i.e. -03 for three foot, -06 for six foot,
-10 for ten foot, etc.) The BC09J has an angled 50 pin connector on one
end, and the straight 68-pin female connector on the other. The BC56H
has a straight 50 pin connector on one end, and a straight 68-pin female
connector on the other. Only DEC made these cables as far as I'm aware.
I have five of them, and I hoard them jealously, like some sort of
bejeweled sacred hoardable thing.
(OK, well maybe they're not THAT rare. You can get them on eBay
frequently for around $15 to $20.)
