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

It all Starterd with a simple integrated circuit board scerwed onto a piwece of plywood.

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

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

It all strted with the invention of the transistor in 1949 by Bell Labs the research arm of the phone company. . The transistor was nothing more than a solid sate electronc switch. The transistor or intyegrated circuit replaced the much larger vacuum tubes of the day. Vacuum tubes were large, hot and unreliable. Transisstors prerformed essentially the same functions as tubes but were smaller , ilghter , coooler and more reliable All said and done they were better ,smalller and more effficient than the vacuum tubes they replaced. . And transistros did not burn out like a vacuum tube.

Transstors allowed a trrend of miniaturization that has led all the way to our present portable smalpl laptp / notebook compuers which can run on batteries. It is hard to visualize for us today that computers used to housae large office buidings themselves along with maintenance bacvkup suppot staff and even their own air conditioners to remove the great amounts of heat the early, primitive computers produced.

In 1959 engnieers at Texas Instruments figured out how to put more than one transistor on the same base and connect these transistors without wires. Thus the next step was born the integrated circuit. The first integrated ciorcuit consistewd of only six transistors. Current computers have in the rabnge of 100 mlilion transistyor equivalents.

In 1969 Intel introduced the 1 k memory chip. This was much larger than anything else produced at the time. Through coordinaion of nItel with a Japanese calculator manbufacturer named Busicomp the next step was made where a generic multipurposse chip was devised. What made this step impportant was that no one chip could do a number of tassks. Previously each chip had a purpose that was burnmt in. Now one integrated chip colud do a number of different functions. One single integrated circuit chip was allmost an entrie computing deviice. The successor to this muilti purpose integrated circuit or CPU was what went on to the basis of our whjole generation and concelpt of petrsonal comuters/

In 1973 some of thee microcomputer kits based on the initial 8080 Itel integrated chip were deveeloped. In the hands of hobbyists these kits were put together and were nothinbg more than blinking lights. Howqever the impetus was on. Many of these early hobbysits went on to become computer indstry gianmts. With Inetl introducing an even much more powerful microproessor chip the computer idnustry was on its way.

A comapny MITS introduced the Altair Computer Kit. The Altair was the imeptus for fledgling software companies, such as Microsoft and Lotus, to writte sotfware progrmas for tese early computers. Among the earlly innovators and producers of sofftware in this field was Microsoft with its first version of Micosoft Basic.

Along came the computer industry leader and stodgy monolith IBM to introduce the first perssonal computer in 1975. The model 1500 was beyond piddly compared to todayts dollar store calculators and cost only $ 9,000.

Next came a smaller upstart Computer Company whcih came to be called Apple Computer. Apple computer introduced the Apple I compuetr in 1976 for the princeyl sum $ 695. Believe it or not original Apple 1 computer consistted of a main circuit board screwed into a piece of plywood. Talk about IBM having to hold its laughter The Apple I appeared to be such a home garage made amater none professionlly 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 would soon go away and diasppear. Yet deepartment heads started buying these simpple comupters for uses in business departmwents. This was in spite of serious advice from IBM experts to corporzations about the perils and shortcomings of these toy computers and outright threats by IBM salespeiople to IT staff and heads.

The Apple I was follwed in 1977 by the Aple II. The Apple II because of its enormous success set the standards for nearly all the important microcomputers to follow, including the IBM PC.

The very core of the early compuetr world IBM International Business Machines the master of the profitable mainframe computer industry had been awoken from its deep profitable slumber by a small upstart computer maker with a simpple computer system that began its product cycle as an integrated circuit board screwed onto a puiece of plywood.
