WordStar 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.
CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors.
Kaypro Corporation was an American home and personal computer manufacturer based in Solana Beach 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.
The Osborne Computer Corporation (OCC) was an American computer company and pioneering maker of portable computers. It was located in the Silicon Valley of the southern San Francisco Bay Area in California. Adam Osborne, the founder of the company, developed, with design work from Lee Felsenstein, the world's first mass-produced portable computer in 1981.
The Osborne 1 is the first commercially successful portable computer, released on April 3, 1981 by Osborne Computer Corporation. It weighs 24.5 lb (11.1 kg), cost US$1,795, and runs the CP/M 2.2 operating system. It is powered from a wall socket, as it has no on-board battery, but it is still classed as a portable device since it can be hand-carried when the keyboard is closed.
A portable computer is a computer designed to be easily moved from one place to another, as opposed to those designed to remain stationary at a single location such as desktops and workstations. These computers usually include a display and keyboard that are directly connected to the main case, all sharing a single power plug together, much like later desktop computers called all-in-ones (AIO) that integrate the system's internal components into the same case as the display. In modern usage, a portable computer usually refers to a very light and compact personal computer such as a laptop, miniature or pocket-sized computer, while touchscreen-based handheld ("palmtop") devices such as tablet, phablet and smartphone are called mobile devices instead.
Ladder is a platform game similar to Nintendo's Donkey Kong written for the CP/M operating system and made to be operated on the early Kaypro line of luggable computers. Ladder was written by Yahoo Software of Los Angeles, California. Along with Star Trek, CatChum and Aliens, Ladder was one of the games that came with the software bundle of the early Kaypro computers.
The Xerox NoteTaker is a portable computer developed at Xerox PARC in Palo Alto, California, in 1978. Although it did not enter production, and only around ten prototypes were built, it strongly influenced the design of the later Osborne 1 and Compaq Portable computers.
A personal computer, often referred to as a PC, is a computer designed for individual use. It is typically used for tasks such as word processing, internet browsing, email, multimedia playback, and gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people in all countries.
Emacs, originally named EMACS, is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on GNU Emacs, directly descended from the original, is ongoing; its latest version is 29.2, released January 2024.
S-BASIC was a "structured" BASIC variant, distributed with Kaypro CP/M systems. It was made by Topaz Programming is distributed by Micro-Ap.
CatChum is a text-only clone of Pac-Man written for the CP/M operating system and made to be operated on the early Kaypro line of luggable computers.
Yahoo Software was an early developer of computer software. During the 1980s, Yahoo Software created the games which were bundled with the early line of Kaypro "luggable" computers. These games include Ladder, CatChum, Aliens and Star Trek.
MINCE is a text editor, originally created for 8080-based microcomputers running the CP/M operating system. Later versions of MINCE were available for GEMDOS on the Atari ST, VAX/VMS, RSX-11, and various flavors of Unix.
KAMAS, an acronym for Knowledge and Mind Amplification System, from Compusophic Systems, then Kamasoft, was, in the 1980s the most influential outliner or outline processor, and the first for CP/M. It was a type of word processor that edited outline elements, enabling showing, hiding, promotion, demotion, and moving of outline trees ("branches"). Each string of text occupied a "leaf". While some modern word processing programs include limited outline capability, none has the features of KAMAS. A number of outline processors exist for MS-DOS, Microsoft Windows, and the Apple Mac platforms. None has achieved a significant market share, or the enthusiastic user base which supported KAMAS.
Perfect Writer is a word processor computer program published by Perfect Software for CP/M. In 1984, Thorn EMI Computer Software acquired an exclusive marketing and distribution licence for Perfect Software's products, and the program was rewritten and released as Perfect II for IBM PC compatible computers. Written in C and famous for its stability, it was an enhanced version of MINCE, which itself was a version of Emacs for microcomputer platforms. Emacs itself was too heavyweight to fit within the 64 KB RAM limit of most microcomputers. Like MINCE, it included a floppy disk based virtual memory system.
The Zorba was a portable computer running the CP/M operating system manufactured in 1983 and 1984. It was originally manufactured by Telcon Industries, Inc., of Fort Lauderdale, Florida, a company specialized in telecommunication equipment manufacturing.
The Dimension 68000 is a microcomputer introduced by the Micro Craft Corporation in 1983 that sought to emulate the Apple II, the IBM PC, and various CP/M-centric computers through a family of coprocessor expansion cards and emulation software. The Dimension 68000 can also run as a standalone computer based on the Motorola 68000 from which it gets its namesake. The computer is mostly the brainchild of Mike Carpenter, a former executive of a scientific instrument manufacturer who incorporated Micro Craft in Dallas, Texas, to develop the Dimension 68000. It had a market lifespan of three years and received mixed, mostly positive, reception from the technology press. Criticism was leveled at the $6,250 price tag for the computer with the full deck of coprocessor cards, as well as the extent of the emulation power of those cards.
