Il Sensor Joystick, a differenza dei suoi simili funzona ad induzione capacitivà attraverso il corpo umano. Per far entrare in funzione il Sensor Joystick è sufficiente sfiorare i comandi. Gli stessi non devono mai essere premuti, perchè potrebbero danneggiare l'apparecchio.

This is an original IBM 912 plugboard panel used in the IBM Type 602-A Calculating Punch, manufactured around 1960. These plugboards were an early form of manual programming, allowing operators to wire custom logic for calculations and data processing. The 602-A was one of the last electromechanical calculators IBM produced before digital computers took over. It's a great piece of computing history. This is the oldest item in my vintage computing collection by about a decade. Can't believe I found it.
