My pleasure, John. It went against my early training, too. If you have
a whole bunch of these to do, you might consider snagging one of those
"helping hand magnifiers"" on ebay if you don't already have one.
They're inexpensive and will save a lot of angst in the process. Just
wait until you get to the 12 and 18 pin connectors! :-) Add a
Panavise Model 201 to hold the connector and you'll be all set!
