DEC VT 420 comm cable?

[Warner Losh]

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.
