Re: Better drawing of the intended target.

[aschneiderjr@xxxxxxxxxxxxx]

This solution does not seem to have the rotational symmetry of the connector we've been 
discussing for some time. Put it another way, you can turn it 180 degrees and plug it in and it 
will work. It also lacks the redundancy of the proposed connector, which will still work even if 
one pin is broken off. If there are offsetting advantages, please explain.

Bob, I've had some issues with sending mail to the IEEE exploder, and if it does not 
propagate could you please repost it? Thanks.
