The Percom one came with a 1771 already plugged into

I asked why - isn't that chip a little expensive to provide, if the
customer already has one that they had to unplug to plug in the board?
One Percom rep told me that they tested and selected "the best" of the
1771s and supplied it, rather than have the customer using the random
quality one that they already had.
A different Percom rep told me that it was because they expected a
large percentage of their customers to "bugger up" the pins on their
1771 in the process of unplugging it.

is the installation manual. Apparently backward chips and bent pins
were a problem. The cheap TI socket on the adapter didn't help
things any.
