    Steve Wozniak Was Born in 1950 Steve Jobs in 1955, Both Attended Homestead High School, Los Altos, California

    Steve Wozniak was born in 1950 Steve Jobs in 1955, both attended Homestead High School, Los Altos, California, Wozniak dropped out of Berkeley, took a job at Hewlett-Packard as an engineer. They met at HP in 1971. Jobs was 16 and Wozniak 21. 1975 Wozniak and Jobs in their garage working on early computer technologies Together, they built and sold a device called a “blue box.” It could hack AT&T’s long-distance network so that phone calls could be made for free. Jobs went to Oregon’s Reed College in 1972, quit in 1974, and took a job at Atari designing video games. 1974 Wozniak invited Jobs to join the ‘Homebrew Computer Club’ in Palo Alto, a group of electronics-enthusiasts who met at Stanford 1974 they began work on what would become the Apple I, essentially a circuit board, in Jobs’ bedroom. 1976 chiefly by Wozniak’s hand, they had a small, easy-to-use computer – smaller than a portable typewriter. In technical terms, this was the first single-board, microprocessor-based microcomputer (CPU, RAM, and basic textual-video chips) shown at the Homebrew Computer Club. An Apple I computer with a custom-built wood housing with keyboard. They took their new computer to the companies they were familiar with, Hewlett-Packard and Atari, but neither saw much demand for a “personal” computer. Jobs proposed that he and Wozniak start their own company to sell the devices. They agreed to go for it and set up shop in the Jobs’ family garage. Apple I A main circuit board with a tape-interface sold separately, could use a TV as the display system, text only.

    Compiler Construction Chapter 11 Compiler Construction Compiler Construction 1 A New Compiler • Perhaps a new source language • Perhaps a new target for an existing compiler • Perhaps both Compiler Construction Compiler Construction 2 Source Language • Larger, more complex languages generally require larger, more complex compilers • Is the source language expected to evolve? – E.g., Java 1.0 ! Java 1.1 ! . – A brand new language may undergo considerable change early on – A small working prototype may be in order – Compiler writers must anticipate some amount of change and their design must therefore be flexible – Lexer and parser generators (like Lex and Yacc) are therefore better than hand- coding the lexer and parser when change is inevitable Compiler Construction Compiler Construction 3 Target Language • The nature of the target language and run-time environment influence compiler construction considerably • A new processor and/or its assembler may be buggy Buggy targets make it difficult to debug compilers for that target! • A successful source language will persist over several target generations – E.g., 386 ! 486 ! Pentium ! . – Thus the design of the IR is important – Modularization of machine-specific details is also important Compiler Construction Compiler Construction 4 Compiler Performance Issues • Compiler speed • Generated code quality • Error diagnostics • Portability • Maintainability Compiler Construction Compiler Construction 5 Compiler Speed • Reduce the number of modules • Reduce the number of passes Perhaps generate machine

  • Introduction Mainframes

    Introduction Mainframes

    LL I I I I Introduction . 11.. V ZI i ..O. There is little question that the current enthusiasm in personal computing was catalyzed by the introduction of the MITS Altair computer kit in January 1975. This computer kit demonstrated by its cost (originally less than $400) that individuals could now afford a computer. And by its design the Altair established a standard bus structure for the personal computing industry. Less than six months after MITS announced the Altair computer, other manufacturers were announcing com- patible memory boards, interface boards, and peripherals. Within the year bus-compatible mainframes were also introduced. Today over 50 manufacturers support what is known as the Standard 100 or S-100 bus derived from the 100-wire bus used in the original Altair computer. Over 20,000 mainframes using the S-100 bus are now in the field. One key reason for the rapid growth of the personal computer industry can be found in the widespread adoption of a standard microcomputer bus. A second key reason can be found in the design innovations in mainframes, memories, and I/O interfaces designed for the S-100 bus. Figure 1. The basic personal computer can accept a number of standard 5" x 10" cards designed for the industry standard S-100 microcomputer bus. A large selection of CPU, memory, and interface cards offers a great deal of flexibility in system Mainframes design. The basic personal computer mainframe consists of a CPU, computer bus, and power supply. Most mainframes are sold in kit form (Figure 1). Without exception in the personal computing industry of manufacturer support for the S-100 bus, no fewer than a microprocessor serves as the CPU.

    The History of Apple Inc

    The History of Apple Inc. Veronica Holme-Harvey 2-4 History 12 Dale Martelli November 21st, 2018 Apple Inc is a multinational corporation that creates many different types of electronics, with a large chain of retail stores, “Apple Stores”. Their main product lines are the iPhone, iPad, and Macintosh computer. The company was founded by Steve Jobs and Steve Wozniak and was created in 1977 in Cupertino, California. Apple Inc. is one of the world’s largest and most successful companies, recently being the first US company to hit a $1 trillion value. They shaped the way computers operate and look today, and, without them, numerous computer products that we know and love today would not exist. Although Apple is an extremely successful company today, they definitely did not start off this way. They have a long and complicated history, leading up to where they are now. Steve Jobs was one of the co-founders of Apple Inc. and one of first developers of the personal computer era. He was the CEO of Apple, and is what most people think of when they think ”the Apple founder”. Besides this, however, Steve Jobs was also later the chairman and majority shareholder of Pixar, and a member of The Walt Disney Company's board of directors after Pixar was bought out, and the founder, chairman, and CEO of NeXT. Jobs was born on February 24th, 1955 in San Francisco, California. He was raised by adoptive parents in Cupertino, California, located in what is now known as the Silicon Valley, and where the Apple headquarters is still located today.
