odel III, and ran all the software of these systems including games. It also had a built in speaker which was compatible with such games software.
A disk operating system is a computer operating system that can use a disk storage device, such as a floppy disk, hard disk drive, or optical disc. A disk operating system must provide a file system for organizing, reading, and writing files on the storage disk. Strictly speaking, this definition does not apply to current generations of operating systems, such as versions of Microsoft Windows in use, and is more appropriately used only for older generations of operating systems.
The RadioShack TRS-80 Color Computer is a line of home computers based on the Motorola 6809 processor. The Tandy Color Computer line started in 1980 with what is now called the CoCo 1 and ended in 1991 with the more powerful CoCo 3. All three CoCo models maintained a high level of software and hardware compatibility, with few programs written for the older model being unable to run on the newer ones.
VisiCalc was the first spreadsheet computer program for personal computers, originally released for the Apple II by VisiCorp. It is often considered the application that turned the microcomputer from a hobby for computer enthusiasts into a serious business tool, prompting IBM to introduce the IBM PC two years later. VisiCalc is considered the Apple II's killer app. It sold over 700,000 copies in six years, and as many as 1 million copies over its history.
The Tandy 1000 was the first in a line of IBM PC compatible home computer systems produced by the Tandy Corporation for sale in its Radio Shack and Radio Shack Computer Center chains of stores.
The Sorcerer is one of the early home computer systems, released in 1978 by the videogame company Exidy. It was comparatively advanced when released, especially when compared to the contemporary more commercially successful Commodore PET and TRS-80, but due to a number of problems, including a lack of marketing, the machine remained relatively unknown, and Exidy eventually pulled it from the market in 1980.
Microsoft BASIC is the foundation product of the Microsoft company. It first appeared in 1975 as Altair BASIC, which was the first BASIC by Microsoft and the first high level programming language available for the Altair 8800 microcomputer.
The IBM PCjr is a home computer that was produced and marketed by IBM from March 1984 to May 1985. The PCjr was positioned as a complement to the very successful IBM Personal Computer (PC), competing with other home computers such as the Apple II series and the Commodore 64. It retains the IBM PC's 8088 CPU and BIOS interface, but provides enhanced graphics and sound capabilities over the original IBM PC, ROM cartridge slots, joystick ports, and an infrared wireless keyboard. The PCjr supports expansion via "sidecar" modules, which are attached to the side of the unit. New software such as King's Quest I showcased its PC gaming capabilities.
The Tandy 2000 is a personal computer introduced by Radio Shack in September 1983 based on the 8 MHz Intel 80186 microprocessor running MS-DOS. By comparison, the IBM PC XT used the older 4.77 MHz 8088 processor, and the IBM PC AT would later use the newer 6 MHz Intel 80286. Due to the 16-bit-wide data bus and more efficient instruction decoding of the 80186, the Tandy 2000 ran significantly faster than other PC compatibles, and slightly faster than the PC AT. The Tandy 2000 was the company's first computer built around an Intel x86 series microprocessor; previous models used the Z80 and 68000 CPUs.
The Adventure Game Interpreter (AGI) is a game engine developed by Sierra On-Line. The company originally developed the engine for King's Quest (1984), an adventure game which Sierra and IBM wished to market in order to attract consumers to IBM's lower-cost home computer, the PCjr.
The Amiga computer can be used to emulate several other computer platforms, including legacy platforms such as the Commodore 64, and its contemporary rivals such as the IBM PC and the Macintosh.
Corvus Systems was a
