Remembering the HP-35 calculator
Recently, the IEEE History Center recognized the HP-35 handheld electronic calculator from the 1970’s with an award as a Milestone in Electrical Engineering and Computing. I owned one of these and a nifty device it was. eWeek has an article about it:
The HP-35 was HP’s first product that contained both integrated circuits and LEDs. Both technologies had been developed in HP Labs, the company’s central research arm.
This little pocket scientific calculator was a specific project that HP co-founder Hewlett himself had requested. At that time, the only computers that could perform transcendental functions such as trigonometric, logarithmic and exponential functions, were bulky machines that couldn’t fit on a desktop, let alone inside somebody’s shirt pocket.
It was the end for the slide rule and the beginning of a new era in calculating devices.
