The TRS-80 Micro Computer System is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy Radio Shack, Z80 [microprocessor]. It is one of the earliest mass-produced and mass-marketed retail home computers.
VisiCalc is the first spreadsheet computer program for personal computers, originally released for Apple II by VisiCorp on October 17, 1979. It is considered the killer application for the Apple II, turning the microcomputer from a hobby for computer enthusiasts into a serious business tool, and then prompting IBM to introduce the IBM PC two years later. More than 700,000 copies were sold in six years, and up to 1 million copies over its history.
Zork is a text-based adventure game first released in 1977 by developers Tim Anderson, Marc Blank, Bruce Daniels, and Dave Lebling for the PDP-10 mainframe computer. The original developers and others, as the company Infocom, expanded and split the game into three titles—Zork I: The Great Underground Empire, Zork II: The Wizard of Frobozz, and Zork III: The Dungeon Master—which were released commercially for a range of personal computers beginning in 1980. In Zork, the player explores the abandoned Great Underground Empire in search of treasure. The player moves between the game's hundreds of locations and interacts with objects by typing commands in natural language that the game interprets. The program acts as a narrator, describing the player's location and the results of the player's commands. It has been described as the most famous piece of interactive fiction.
Xenix is a discontinued version of the Unix operating system for various microcomputer platforms, licensed by Microsoft from AT&T Corporation in the late 1970s. The Santa Cruz Operation (SCO) later acquired exclusive rights to the software, and eventually replaced it with SCO UNIX.
Microsoft BASIC is the foundation software product of the Microsoft company and evolved into a line of BASIC interpreters and compiler(s) adapted for many different microcomputers. It first appeared in 1975 as Altair BASIC, which was the first version of BASIC published by Microsoft as well as the first high-level programming language available for the Altair 8800 microcomputer.
Rogue is a dungeon crawling video game by Michael Toy and Glenn Wichman with later contributions by Ken Arnold. Rogue was originally developed around 1980 for Unix-based minicomputer systems as a freely distributed executable. It was later included in the Berkeley Software Distribution 4.2 operating system (4.2BSD). Commercial ports of the game for a range of personal computers were made by Toy, Wichman, and Jon Lane under the company A.I. Design and financially supported by the Epyx software publishers. Additional ports to modern systems have been made since by other parties using the game's now-open source code.
Colossal Cave Adventure is a text-based adventure game, released in 1976 by developer Will Crowther for the PDP-10 mainframe computer. It was expanded upon in 1977 by Don Woods. In the game, the player explores a cave system rumored to be filled with treasure and gold. The game is composed of dozens of locations, and the player moves between these locations and interacts with objects in them by typing one- or two-word commands which are interpreted by the game's natural language input system. The program acts as a narrator, describing the player's location and the results of the player's attempted actions. It is the first well-known example of interactive fiction, as well as the first well-known adventure game, for which it was also the namesake.
Level 9 was a British developer of computer software, active between 1981 and 1991. Founded by Mike, Nicholas and Pete Austin, the company produced software for the BBC Micro, Nascom, ZX Spectrum, Commodore 64, Oric, Atari, Lynx 48k, RML 380Z, Amstrad CPC, MSX, Amiga, Apple II, Memotech MTX, and Enterprise platforms and is best known for its successful text adventure games until a general decline in the text adventure market forced their closure in June 1991.
Temple of Apshai is a dungeon crawl role-playing video game developed and published by Automated Simulations in 1979. Originating on the TRS-80 and Commodore PET, it was followed by several updated versions for other computers between 1980 and 1986.
James Gordon Letwin is an American software developer and one of the eleven early Microsoft employees who posed for an iconic staff portrait taken in Albuquerque in 1978.
The TRS-80 Model 100 is a portable computer introduced in April 1983. It is one of the first notebook-style computers, featuring a keyboard and liquid-crystal display, in a battery-powered package roughly the size and shape of a notepad or large book. The 224-page, spiral-bound User Manual is nearly the same size as the computer itself.
Apple Panic is a game for the Apple II programmed by Ben Serki and published by Broderbund Software in 1981. Apple Panic is an unauthorized version of the 1980 arcade game Space Panic, the first game with ladders and platforms. While the arcade original remained obscure, Apple Panic became a top seller for home computers. It was ported to the Atari 8-bit family, VIC-20, IBM PC, and TRS-80.
SoftSide is a defunct computer magazine, begun in October 1978 by Roger Robitaille and published by SoftSide Publications of Milford, New Hampshire.
Following the introduction of the IBM Personal Computer, or IBM PC, many other personal computer architectures became extinct within just a few years. It led to a wave of IBM PC compatible systems being released.
The TRS-80 Model II is a computer system launched by Tandy in October 1979, and targeted at the small-business market. It is not an upgrade of the original TRS-80 Model I, but a new system.
Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single, non-technical user. These computers were a distinct market segment that typically cost much less than business, scientific, or engineering-oriented computers of the time, such as those running CP/M or the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business computers. Their most common uses were word processing, playing video games, and programming.
Olympic Decathlon is a sports video game written by Timothy W. Smith for the TRS-80 and published in 1980 by Microsoft. In the game, the player competes in ten track and field events. The gold medalist for decathlon in the Montreal 1976 Summer Olympics, Caitlyn Jenner, is a character. It was ported to the Apple II in 1981. The 1982 version for the IBM PC was renamed Microsoft Decathlon.
