History Personal Computer
In the year 1968, a demonstration given by SRI researcher Douglas Englebert could be called the biggest of all demos so far. The demo gave a fore-sight of how working lifestyles would be in the 21st century with e-mails, word processing, hypertext, the mouse and video conferencing. This particular demonstration needed a lot of assistance from the support staff and also a mainframe computer that had the facility of time-sharing. It was found that all of this was way too expensive for businesses that operated individually in those days. |
However, the dawn of the 1970s saw many in academics or institutions that conducted researches, had paved way for a single-person to operate the computer for longer periods of time in the interactive mode. It has to be understood that it was too costly for an individual to own one of these systems.
In the very same 1970s, Hewlett Packard brought out the completely BASIC computer which was programmable and was the size of a desk. These computers included a single line display, a keyboard and printer. 1973 saw the introduction of The Wang 2200 which had a complete CRT and could store a cassette tape.
1975 was the year for IBM 5100 which had a tiny CRT display and had the options of being programmed in APL and BASIC. Apple I Circuit Board was sold in 1976 and had the capacity to house 30 chips and the very first personalized computer was made by Commodore PET in 1977.
All through the late 1970s and the 1980s computers were developed and personalized to enhance the user's experience to what we have nowadays. Computers used for business have acquired sound quality and color graphics capabilities and this goes for the same in personal computers too.
Personal computers have come a long way from what they were when they were developed, what we now have is the state of art in computers and we enjoy the experience.
