I had a huge struggle with soldering a couple of DB-9 connectors, my
vision and fine motor control just aren't what they used to be. And, I
only had to make 5 connections on the DB-9's, it took me close to an
hour. These are for a DRO, I've been using a break-out box until now on
the mismatched scales and display. Remember, the display bit the dust a
while ago.

I did have the connectors locked in a miniature vice but I couldn't
think of any other techniques that would help.
