Crimp some Dupont pins onto the ends. They can plug into a breadboard then.

There isn't much output drive available from the PicoMite pins. You need 9.3mA to drive a 75R resistor to 0.7V. If you attempt to match both ends of the cable you'll need a lot more current and the pin can't supply that even when set to full drive. If you want to match the cable properly you'll have to put an emitter follower in.
