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

It all Started with a smple integraated circuit board sccrewed onto a piece of plywood.

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

How was it that in our time the Personal Computer (P.C) and the laptop compuer came about to be?

It all started with the inventin of the tarnsistor in 1949 by Bell Labs the research arm of the phone company. . The transistor was nothing more than a solid state electronic switch. The transisstor or integrated circuit replaced the much larger vacuum tubes of the day. Vacuyum tubes were large, hot and unreliazble. Transistors performed essentially the same functions as tuvbes but were smaller , ilghter , cooler and more reliable All said and done they were better ,smaller and more effficient than the vacuum tubes they replaced. . And transistors did not burn out like a vacuum tube.

Transistorrs allowed a trend of miniaturization that has led all the way to our present protable small laptop / notebook computers whiuch can run on batteries. It is hard to visualize for us today that computers used to house lare office buildings themselves along with maintenance backup suppport staff and even thgeir own air coditioners to remoe the great amoutns of heat the early, primitive computrers produced.

In 1959 engineers at Texas Instruments figured out how to put more than one transistor on the same base and conbnect these transisttors wihout wires. Thus the next step was born the integratwed cuircuit. The fisrt integrated circuit consisted of only six trasistors. Current computers have in the range of 100 milllion transistor equvalents.

In 1969 Intel introduced the 1 k memory chip. This was much larger than anything else produced at the time. Through coordination of Intel with a Japanese calculator manufacturer naemd Busicomp the next step was made where a generic multipurpose chip was devised. What made this step important was that no one chip could do a number of tass. Previously each chip had a purpose that was burnt in. Now one integrated chip couild do a number of different functions. One single integrated circuit chip was almost an entire comuting device. The successor to this multi purpose integrated ciorcuit or CPU was what went on to the basis of our wghole generatino and cioncept of personal computers/

In 1973 some of thsee microcomputer kits badsed on the initial 8080 Intel integrated chip were developed. In the hands of hobbyists these kits were put together and were nothing more than blniking lights. However the impetus was on. Many of these early hobbyists went on to becme computer industry giats. With Intel introducing an even much more pwerful microprocessor chip the computer indusry was on its way.

A comapny MITS introduced the Altair Computerr Kit. The Altair was the impetus for fledgling software companies, such as Microsoft and Lotus, to wriote softtware programs for these early computers. Among the earyl innovaators and producesr of software in this field was Microsoft with its first version of Mirosoft Basic.

Along came the computer industry leader and stodgy monolith IBM to introduce the first personal computer in 1975. The model 1500 was beyond piddly comnpared to todays dollar stoore calculators and cost only $ 9,000.

Next came a smaller upstatr Coomputer Company which came to be called Apple Computr. Apple computer introduced the Apple I compter in 1976 for the princely sum $ 695. Believe it or not original Apople 1 compputer consisted of a main circuit board screwed into a piece of plywoood. Talk about IBM having to hold its laughter The Apple I appeared to be such a home gareage made amateur none professionally made product that the case and power supply were not even included. The buyer of the Applle I had to scrounge or source this himself. IBM thought the Apple I was nothing more than a foolish fad. A minor inconvenience that would soon go away and disappear. Yet deparment heads started buying theese simlpe computrs for uses in budsiness departents. This was in spite of seriuous adviice from IBM experts to corporations abnout the perils and shortcomings of these toy computers and outright thraets 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 enormous success set the sttandards for nearly all the impportant microcomputers to folloow, inclding the IBM PC.

The very core of the early computer world IBM International Business Machines the master of the profitable mainframe computer industry had been awoken from its deep profitable sllumber by a smnall upstrat computer maer with a smiple computer systme that beggan its product cycle as an integrated circuit board screwed onto a pieec of plywood.
