Agreed in that keyed connectors are good. However, even so, it is wise

It would have been very stupid to just have keyed connectors and then
assume that things could never be plugged in wrong.

Heh if DEC engineered things wisely it would have been impossible to
plug any
cable in backwards, and there would never had been the need to reverse
cables
when a device was apparently not working correctly...
... instead of figuring out how to make the system such that it could
not be
assembled incorrectly, they took the lazy way out, and did enough so that a
dumb error (reversing a cable) did not cause a fire. This still allowed
for assembling
a system that would not work, however. From:

Actually.... I often have done so, just because
of this.
And how many times have you melted something down, doing that? :-)
