I don't have a source for MMJ cables,
but I do have a US/Domestic source for MMP's
(the offset modular connectors). . .

They are .14 / each for flat cable, and .41 / each for round cable.
Last I checked, they don't ship internationally.
There are two different styles of DecConnect cables;
both inverted, and not inverted.?? The only difference
of course, is that one connector is flipped on one end.
When used with genuine DEC adapters, one?style worked
for printers (DCE), and the other style worked with terminals (DTE).
Back in the early 90's, our office used uVax 2000's,
connected to VT220's. along with various printers,
connected using DEC MMJ <> DB25 adapters.
You couldn't simply swap the DecConnect cables
because of the inverted MMP's on some of the cables.
All of our cabling and adapters were unmodified DEC products.
If you're really in a pinch, you can always
pop the connector off of one end of the cable,
and re-crimp it by hand.
It's a bit cumbersome, but you can use a thumb-tack
to lift the gold contacts out of the connector, and then
use a small flat-blade screwdriver to push them back in.
Just be careful not to stab yourself in the process.? ;-)
