Keyboard of the Crusader II is shown here. There are different Mylar panels to the Crusader or the Commando, but they use the same keyboard. Note the Estop has been removed on Commando panel. Shown are examples of two front panels with the LEC keyboard attached. If you look carefully you can see the edge of the card on first 2 pictures. The Crusader II L is original. When mounted in the enclosure, only 2 edges show, and they are well secured. There are many of these in the field and we have yet to have the LEC replacement to fail.
