Motorola 6809The Motorola 6809 ("sixty-eight-oh-nine") is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code and an orthogonal instruction set architecture with a comprehensive set of addressing modes.
Breakout (video game)Breakout is an arcade video game developed and published by Atari, Inc. and released on May 13, 1976. It was designed by Steve Wozniak, based on conceptualization from Nolan Bushnell and Steve Bristow, who were influenced by the seminal 1972 Atari arcade game Pong. In Breakout, a layer of bricks lines the top third of the screen and the goal is to destroy them all by repeatedly bouncing a ball off a paddle into them. The arcade game was released in Japan by Namco.
Apple II graphicsApple II graphics debuted on the 1977 Apple II and was used throughout the Apple II line. They consist of a 16 color low resolution mode and a high resolution mode where visuals are dependent on artifact color. The Apple IIe added "double" versions of each of these, most prominently "double high resolution" with twice the horizontal resolution in 16 colors. Internally, Apple II graphics modes are idiosyncratic and do not simply use a linear frame buffer.
WDC 65C02The Western Design Center (WDC) 65C02 microprocessor is an enhanced CMOS version of the popular nMOS-based 8-bit MOS Technology 6502. The 65C02 uses less power than the original 6502, fixes several problems, and adds new instructions. The power usage is on the order of 10 to 20 times less than the original 6502 running at the same speed; its reduced power consumption has made it useful in portable computer roles and industrial microcontroller systems.
DBasedBase (also stylized dBASE) was one of the first database management systems for microcomputers and the most successful in its day. The dBase system includes the core database engine, a query system, a forms engine, and a programming language that ties all of these components together. dBase's underlying file format, the file, is widely used in applications needing a simple format to store structured data. Originally released as Vulcan for PTDOS in 1978, the CP/M port caught the attention of Ashton-Tate in 1980.
WordStarWordStar is a word processor application for microcomputers. It was published by MicroPro International and originally written for the CP/M-80 operating system, with later editions added for MS-DOS and other 16-bit PC OSes. Rob Barnaby was the sole author of the early versions of the program. Starting with WordStar 4.0, the program was built on new code written principally by Peter Mierau. WordStar dominated the market in the early and mid-1980s, succeeding the market leader Electric Pencil.
Homebrew Computer ClubThe Homebrew Computer Club was an early computer hobbyist group in Menlo Park, California, which met from March 1975 to December 1986. The club had an influential role in the development of the microcomputer revolution and the rise of that aspect of the Silicon Valley information technology industrial complex. Several high-profile hackers and computer entrepreneurs emerged from its ranks, including Steve Jobs and Steve Wozniak, the founders of Apple Computer.
KayproKaypro Corporation was an American home and personal computer manufacturer based in San Diego in the 1980s. The company was founded by Non-Linear Systems (NLS) to compete with the popular Osborne 1 portable microcomputer. Kaypro produced a line of rugged, "luggable" CP/M-based computers sold with an extensive software bundle which supplanted its competitors and quickly became one of the top-selling personal computer lines of the early 1980s.
