The Melcor 380 is a vintage calculator manufactured in 1973 by the Melcor Company. It was available at the Howland Waterfall Shopping Centre for approximately £89.95, which would have been half of months pay for many people. It was one of the earliest calculators with two memory registers, one for storing a constant and the other for general-purpose use. With two storage registers, its calculating power and usefulness increased.
As well as basic functions, this calculator could do chain and mixed operations including suppression of unnecessary zeros. In 1973, the Melcor calculator was one of the most advanced pocket sized calculating instruments available to the public measuring 78 mm × 153 mm × 23 mm, and weighing 5 oz.
I just love good calculator design and this classic product was one of the best of its time.
This calculator had a power save function, which switched OFF the display after 30 seconds of non-use. A single segment in the middle remained lit to indicate that the calculator was in power save mode.
Press the 'D' key to restore the display.
Keyboard technology has improved much over the years. In 1970s, Klixon was a famous name known to produce the best quality keyboards.
This calculator has the “Full Travel Keyboard”, which has large keys that are spaced out. They are made of hard plastic with finger-contoured surface. Each key has a dedicated spring to push it back up, however there is no click noise or feel to the keys when depressed.
