  Do you mean something like the 2.54mm dual-row
"Dupont" connector
 shells taking crimp pins?
 e.g. eBay 330875532644 
Yes, that's it! How on earth did you find that? I looked on eBay (and then
Googling) for several hours, and couldn't!! :-)

  Do you need ones like used on the M7800 (DL11) and
KL8?
 I have 20ma cables for these 
Thanks; those are indeed the kind/size I'm looking for (quite a few DEC
boards use them), but I think I'm set now (above).

  the housing is technically 44 positions because it
goes all the way to
 the edges, but the DEC connectors (like the IDC ribbon-cable
 connectors) skip the outer pairs so you only ever use the middle 40
 pins out of 44. 
Interesting... I have a cable with 40-pin connectors (on an old IDE cable;
these are not keyed) and I tried plugging it in, and there is no space at all
on the sides (unlike, say, when one plugs a 10-pin shell into a 14-pin
DLV11-J connector). But looking at the connector carefully, I see that the
side arms of the top retainer piece take up space on the sides - looks like
just enough for a pin. So maybe the '40 pin' Berg headers really are
technically 44 pin size (although they do have only 40 pins).

Speaking of keying... does anyone know the name (let alone a source) for the
little plugs (usually white) that can go into one of the holes on one of those
connector shells, to key it so it can only go in one way round?

Thanks everyone, for all for the help!
