I hadn't realised there was a choice!

I just checked my Microchip Universal Programming Module (AC162049) which has, confusingly, a *black* 3M
socket, and its instructions say, in BIG LETTERS: "***Warning*** ZIF socket handle must be in the up (locked)
position prior to programming the microcontorller or it will not program properly".  Handle-up on this moves
the gold-plated leaves in each slot apart, which I had previously thought was "open".

Doing it either way will grip the IC pins, but doing it their way means the contact is on one side only and
the holding pressure is from a spring.  Treating handle-down as closed means both-sides contact, with the
force of pushing the handle down applying the holding pressure.

Thoughts, anyone?

Incidentally, the "3M" on this socket looks just like the ones we're starting to call "counterfeit"!  :-)
