Thanks, I have updated the document. I had less trouble building it in
the
first place than figuring out what I built.
LOL! I often find that :-)
The adapter has a normal
3M in it and I had though I got the pin 1 backward on it. Apparently
when I built it I knew they were opposite but since forgot.
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
different?
