The first couple of times I came across Berg connectors (rather than, say,
3M, which I was used to on micros) I was *thoroughly* confused by what I
saw as the "wrong" way of doing it. A healthy dose of DEC machines with
3rd party parts fixed that. Now I use them less, I have to think about it
again, though.

I wonder how this confusion came about? Everyone else uses "stripe on the
right" (but not, IIRC, for D-connectors and some others) but I think Berg
predates 3M et al headers? If so, how come 3M and the rest chose to be
