A couple years back you could buy a DEC H8220 bag of 50 MMJ connectors
from Vnetek for around $15. I bought a few bags of 50 connectors at
the time. As far as I know Vnetek Communications had acquired the
rights to DECserver products, and might have previously operated as
Digital Networks. Unfortunately Vnetek Communications appears to have
disappeared without a trace a while ago.

If you want to make up a large number of MMJ cables using some
original DECconnect cable, here is a listing of a 1000ft spool of
original DEC H8240 cable. Some people have bought some of those spools
and reported that they are original DECconnect branded cable:

You used to be able to buy a Paladin (then Greenlee, then Tempo?)
PA8035 CrimpALL tool which included the PA2067 MMJ die. You can still
find the PA8000 CrimpALL tool without a die, but the PA2067 MMJ die
was discontinued a while ago and doesn't appear easy to find now. I
bought a PA8035 back when I bought the MMJ connectors. Never got
around to building up any MMJ cables yet, I already have enough
original cables on hand for now.
