I know that the early Macintosh KB cables are NOT a standard telephone cord, and using one is a guaranteed way to fry either the computer or board. I've heard the cords described as being "reversed." I've assembled my fair share of RJ-11 cables, and generally there is a rib on one side of the cable's outer casing that allows you to keep things aligned. When assembling a "normal"(4 conductor) telephone cord, one keeps both RJ-11 connectors such that the "rib" is on the same side of both connectors. What I'm wondering is if I put a cable together with one RJ-11 connector reversed from the the other, will I get a functional Macintosh keyboard cable?
