I started coding in then 1960’s on a Ferranti Mercury. It was as big as a house and had less computer power than my watch. But at the time we thought it was pretty cool. Over the years, Moor’s Law turned out to be pretty accurate. The most powerful computers doubled in power about every two years. Commercial systems got smaller. From as big as a house, to the size of a room, to the size of a desk, then a largeish box in a rack.
But in the mid 1970’s something happened off the Moore’s Law track. They managed to fit all the components of a low-power computer on a single chip. They were mass produced and relatively cheap. The engineers that built it had in mind using them for process control, calculators or computer terminals.
Enter Gary Kildall
But a genius called Gary Kildall saw another potential use for these devices.
