Sharp Corporation introduced in the 1977 with the EL-8036 and this EL-8130 the World’s first touch key calculator using a membrane keypad.
Another Sharp breakthrough was the development of the membrane's flat keypad, which allowed the calculator to shrink even further to only 0.2" in thickness (the EL-8130 was called the "super thinman"). Since the keys lack any tactile response when pushed, these units had a special key which activated a beep that sounded upon each key press. This "sensor touch" keys used in many later Sharp calculators, had a musical note symbol on the key.
Another two year later thickness was reduced to unbelievable 1.6mm (0.35"). Don't miss the EL-8152.
