Hewlett-Packard introduces the HP-9100 desk calculator
|
1st September 1968 The Hewlett-Packard HP9100 series calculator was the first of many calculators designed and manufactured by HP for scientists and engineers. HP introduced the HP 9100A in the September 1968 issue of the HP Journal. A few months later the 9100B model followed, which had double the memory capacity. These machines combined a multi-line CRT display, fast calculation capability, scientific functions, multi-register storage, and programming capability in a calculator package that would fit on a desktop. In 1968, the Hewlett-Packard company was primarily a test equipment manufacturer. Their only other computing product at the time was the 2116A minicomputer. Both the 9100 and 2116 were designed as rugged instruments with special features of use for instrumentation and control in combination with other HP test gear. The first documented use of the phrase "personal computer" appeared in 1968 Science magazine advert for the HP-9100. Related information: Image:
