Hi friends,
I just received a refurb'd VT-420 with green screen. I see that I need a special 6
pin/modular-type cable for the comm port. I located the adapter to get to DB25 (
https://www.ebay.com/itm/262041938994 ) but I need the interconnecting cable. Anyone know
what it is called? Anyone have one for sale?

Eugene,
Its called an MMJ cable, Modified Modular Jack. The price from the Stonewall
link in Bills mail seems typical commercial.
Pretty some one in the USA was making these for less.
I have the bits to make some in the UK but shipping gets expensive.

In a pinch, you can use a normal modular jack (RJ45 I think) with the
retaining tab cut off. All MMJ does is move that tab. The idea, back in the
day, was that you wouldn't want to confuse phone and serial cables. Sounds
sane, but the MMJs were hard to get a hold of and a real pita in practice.

I've got 1000 feet of DEC OfficeConnect flat cable, a bunch of MMJ ends,
and the crimp dies for them, if anyone finds themselves in need of cable.
Thanks,
Jonathan

Also I am in Spain but the cable, ends and crimps are in the UK.
