Creators of the Modern Computer

"The first Apple was only a culmination of my expereince of living. " - Steve Wozniak, Co-Founder Apple Computers

Following the intro of the Altair, a growth in personal computers occurred, and fortunately for the consumer, the next circular of home computers had been considered useful and a pleasure to use.

In 1975, Dorrie Wozniak was working for Hewlett Packard (calculator manufacturers) through day and playing pc hobbyist by night, trying out the early computer kits such as the Altair. "All the little personal computer kits that were being promoted to hobbyists in 75 were square or rectangle-shaped boxes with non easy to understand switches on them... " stated Wozniak. Wozniak realized that the costs of some computer components (e. g. microprocessors as well as memory chips) had gotten therefore low that he could purchase them with maybe a month's income. Wozniak decided that, which includes help from fellow enthusiast Steve Jobs, they could develop their own computer.

On Apr Fool's Day, 1976, Sam Wozniak and Steve Work released the Apple We computer and started Aple. The Apple I was the very first single circuit board computer system. It came with a video user interface, 8k of RAM along with a keyboard. The system incorporated a few economical components, including the 6502 processor (only $25 bucks - designed by Rockwell and also produced by MOS Technologies) along with dynamic RAM.

The set showed the prototype Apple company I, mounted on plywood with the components visible, at a conference of a local computer dabbler group called "The Self-made Computer Club" (based within Palo Alto, California). An area computer dealer (The Byte Shop) saw it in addition to ordered 100 units, offering that Wozniak and Careers agreed to assemble the packages for the customers. About 100 Apple Is were constructed and sold over a 10 month period, for the irrational price of $666. 66.

Within 1977, Apple Computers was integrated and the Apple II laptop or computer model was released. The first To the west Coast Computer Faire happened in San Francisco the same yr, and attendees saw the general public debut of the Apple 2 (available for $1298). The actual Apple II was additionally based on the 6502 processor, however it had color graphics (a first for a personal computer), and used an sound cassette drive for storage space. Its original configuration included 4 kb of MEMORY, but a year later this was improved to 48 kb associated with RAM and the cassette generate was replaced by a floppy disk drive.

The Commodore PET (Personal Electronic Transactor or maybe rumored to be given its name the "pet rock" fad) was designed by Chuck Claim. It was first presented in the January, 1977, Winter Gadgets Show and later at the Western Coast Computer Faire. Your pet Computer also ran on the 6502 chip, but it cost just $795, half the price of the actual Apple II. It integrated 4 kb of RAM MEMORY, monochrome graphics and a good audio cassette drive with regard to data storage. Included was obviously a version of BASIC inside 14k of ROM. Ms developed its first 6502-based BASIC for the PET after which sold the source code in order to Apple for AppleBASIC. Its keyboard counterpart, cassette drive and little monochrome display all suit within the same self included unit.

Note: Steve Work opportunities and Steve Wozniak in one point in time showed the particular Apple I prototype to be able to Commodore, who agreed to purchase Apple. Steve Jobs after that decided not to sell to Commodore, who bought MOS Technologies instead and then designed your pet. The Commodore PET had been seen at the time to be a main rival of the Apple.

Inside 1977, Radio Shack released its TRS-80 microcomputer, furthermore nicknamed the "Trash-80". It had been based on the Zilog Z80 processor chip (an 8-bit microprocessor in whose instruction set is a superset of the Intel 8080) as well as came with 4 kb regarding RAM and 4 kilobytes of ROM with FUNDAMENTAL. An optional expansion package enabled memory expansion, and also audio cassettes were utilized for data storage, similar to the DOG and the first Apples. More than 10, 000 TRS-80s have been sold during the first 30 days of production. The later on TRS-80 Model II arrived complete with a disk push for program and information storage. At that time, only The apple company and Radio Shack experienced machines with disk turns. With the introduction of the hard drive drive, applications for the pc proliferated as distribution involving software became easier.
