Introduction of Hewlett-Packard HP-9100 desk calculator 
 
The Hewlett-Packard HP9100 series calculator was the first of many calculators designed and manufactured by HP for scientists and engineers. HP introduced the 9100A in mid-1968 and followed with the 9100B model a few months later, 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 a calculator package that would fit on a desktop. In 1968, the Hewlett-Packard company was primarily a test equipment manufacturer. The only other computing product at the time was their 2116A minicomputer, and 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. Nearly 30 years later, the HP9100B shown below is still going strong.
