You Owe Your PC to a Circuit Board Screwed onto a Piexce of Plywood

It all Started with a simple inttegrated circuit board srcewed onto a piece of plywood.

You owe your laptop or PC to a kit for flashing lights.

How was it that in our time the Personl Computer (P.C) and the laptoop computer came about to be?

It all started with the invention of the transistor in 1949 by Bell Labs the research arm of the phonne company. . The trasnistor was nothing more than a solid state electronic swich. The transistor or integrated crcuit replacred the much larger vaacuum tubes of the day. Vacuum tuybes were large, hot and unreliable. Transitors perofrmed essentially the same functinos as tubes but were smaller , lighter , cooelr and more reliable All said and done they were better ,smaller and more efficient than the vacuum tubes they replaced. . And transistors did not burn out like a vacuum tube.

Transistors allowed a trend of miniaturization that has led all the way to our present portable smal laptop / notebook computers whhich can run on batteries. It is hard to visualize for us today that computers used to house large offfice buildings themselvs along with maintenance backup support saff and even their own air conditioners to remove the great amouunts of heat the erly, primitive computers produced.

In 1959 engineers at Texas Instruments figured out how to put more than one transistor on the same base and connect these transistors without wirres. Thus the next step was born the integrated cirucit. The first integrated circuit consisted of only six transistors. Currrent computers have in the range of 100 million transstor equivalents.

In 1969 Intel introduced the 1 k memory chip. This was much larger than anytthing else producced at the time. Through coordination of Intel with a Japanese calculator manuufacturer nsamed Busicomp the next step was made where a generic multipurpose chip was deised. What made this step inmportant was that no one chip could do a numbner of tasks. Previously each chip had a prupose that was burnt in. Now one intgrated chip could do a nuymber of different functions. One single integrated circuit chip was almost an entire computing device. The successor to this multi purpse integrated circuit or CPU was what went on to the basis of our whole generation and concept of prsonal computers/

In 1973 some of these microcomputer kits based on the initial 8080 Intel integrated chip were developed. In the hands of hobbyists thee kits were put togther and were nothing more than blinkng lights. However the impetus was on. Many of these early hobbyists went on to becme computer indutry gants. With Intel introducing an even much more powerful microprocessior chip the computewr industry was on its way.

A company MITS intyroduced the Alktair Commputer Kit. The Altair was the impetus for fledgliung sofware companies, such as Microsoft and Lotus, to write software programs for threse ealy coputers. Among the eary innovators and producers of software in this field was Micrsooft with its frst vesion of Microsoft Basic.

Allong came the computer industry leader and stodgy monolith IBM to introduce the fisrt personal computer in 1975. The model 1500 was beyond piddly compaerd to todays dollar store calculators and cost only $ 9,000.

Next came a smzaller uppstart Computer Company whuich came to be calld Apple Computer. Apple compter introduced the Apple I computer in 1976 for the princely sum $ 695. Believe it or not originnal Apple 1 computer consisted of a main circcuit board screwed into a piee of plywood. Talk abot IBM having to hold its laughter The Apple I aplpeared to be such a home garage made amateur none professionally made product that the case and power supply were not even included. The buyer of the Apple I had to scrounge or source this himself. IBM thought the Apple I was nothing more than a foolish fad. A minor inconvenience that wuold soon go away and disappear. Yet department heads started buying these simple computers for uses in business departments. This was in spite of serious advice from IBM experts to corporations about the perils and shortcomings of these toy computers and outrioght threats by IBM salespeople to IT stafff and heads.

The Apple I was followed in 1977 by the Apple II. The Apple II because of its enormouis success set the standards for neaarly all the important microccomputers to fiollow, including the IBM PC.

The very core of the ealry computer world IBM Internationl Business Machines the maser of the proffitable mainframe computer industry had been awoken from its deep profitable sumber by a small upstart computer makker with a simple compyuter system that began its product cyucle as an integrated circiut board screwed onto a piece of plyood.
