I've got to admit that I recently found I had some boxes of these cords 
and as they were rather tarnished, considered tossing them into the 
cable recycling pile :-(

Now that you have reminded me what they are (I checked they fitted 
computer lab), I have checked the dimensions you gave and can confirm 
the approx dimensions of the pins and most of the cords.  But two 
changes, the green ones are 16.75" inches long, and the blue ones are 
24.75" long.

Can anyone independently verify the number of each cord type in a set?
