How much did the first personal computer cost?

I must say that April 1 was a suitable day for the birth of a company that was going to do business at that time not at all serious, namely the sale of personal computers. In 1976, in the United States, this business seemed highly dubious. Who could be interested in personal computers at that time? Only crazy hams. For them, parts were sold in the store, from which the Altair 8800 home computer could be assembled without special difficulties. Those who did not want to bother with a soldering iron and with a setting could ask the seller in the store to assemble it for a small additional fee. A home computer could be connected to a TV and, paying for an additional communication unit, to a household cassette recorder. What to do next? No one knew. So the founders of the Apple company, the famous Steve Jobs (1955−2011) and the now less known Steve Wozniak, not only two namesakes, but also two friends, decided to take up a clearly unsuccessful business. Fools! Stupid kids! Continue reading

What is a “computer generation”? Generation 1: Tube

In our era of multiprocessing and distributed computing, the once seemingly important division of computers into generations has already been forgotten a little. The first generation is tube computers, the second is transistor computers, the third is integrated circuit computers, and the fourth is microprocessor-based computers.

In the beginning there were ferrite rings and electron tubes. The direct access memory, or RAM, which was called RAM (the random access memory, or simply “memory”) as a girl, consisted of ferrite rings. Each ring was stitched with several windings. The write current went along one, the read current on the Continue reading

How does a person control a computer? Present and future

What devices do we use to control computers with? At first there were the tumblers, then the electric typewriters. The technique developed, color video monitors appeared, various new devices appeared that made it possible to control a computer. Color monitors have been very popular since the 1990s for the then latest Windows OS. And at the same time, many devices were invented, invented back in the DOS era and found use after it – in the Windows era. Photo: Depositphotos Computer mouse The mouse was patented in 1970. The author of the “mouse” is California engineer Douglas Engelbard. As a standard computer peripheral, a computer mouse began to act in the Xerox 8010 mini-computer, and it cost then, if you translate it into modern money, no less than $ 1,000! As time went on, technology improved, the Apple mouse in 1983 already began to cost only $ 25, and when the world began to take over the Continue reading
