Pressing a key connects approx. 12K between a group-1 wire and a group-2 wire. The connectors for the 2 mylar cables exist, but only in SMT form. You can solder 30ga. wires to the pins of the connectors (but not the cables -- they'll melt) but only if you're very good with your soldering iron. Pin spacing is 1 mm. Wires on connectors are in three groups: group 1 for keyboard (8 wires), group 2 keyboard (the 11 wires in the other cable), and group 3 (6 wires on the first cable). Group3 is for the joystick/mouse thingy. Needs to be mounted on or in some framework, but that's not hard. Keys have very good feel. Excellent, and the price is right. Was this review helpful to you?
