Hewlett-Packard has played an exceptional role in the history of handheld computers. This company gave us truly remarkable palmtops 100LX/200LX, PDA iPaq hx4700 and Jornada 720. Some people still use these devices on a daily basis.
But what was the first handheld computer created by Hewlett-Packard?
You may consider HP-75C as the first HP handheld. The device is not very small, and the possibility of using it as a handheld is questionable.
But actually it depends on the criterias of a handheld computer.
Another candidate is the HP-67, which was introduced in 1976.
HP-67 was world’s first Turing-Complete handheld device. This is a strong argument in favor of transferring this device from calculators to the category of handheld computers.

I met the owner of this device few days ago. The guy told me that he repaired this device by himself, and now uses it for programming microcontrollers. He writes programs in C and Pascal. The main advantages he mentioned were small size and extremely long battery life.
