ET-1110 specifications

The Radio Shack ET-1110, a remarkable handheld electronic device from the 1980s, is a notable example of early consumer technology that focused on portability and user-friendliness. Originally released as a combination of a pocket-sized calculator and a basic programming tool, the ET-1110 appealed to a wide range of users, from students to professionals.

One of the main features of the ET-1110 is its sleek, compact design. This device was designed to be lightweight and portable, making it easy to carry around in a bag or even in a pocket. The ergonomic layout included a comfortable keypad that allowed users to input data quickly and efficiently. Its liquid crystal display (LCD) made it easy to read under various lighting conditions, a significant advantage at the time.
