AMSDOS
AMSDOS is a disk operating system for the 8-bit Amstrad CPC Computer (and various clones). The name is a contraction of Amstrad Disk Operating System. AMSDOS first appeared in 1984 on the CPC 464, with added 3 inch disk drive, and then on the CPC 664 and CPC 6128. Relatively fast and efficient for its time, AMSDOS was quicker and more effective than most of its contemporaries. AMSDOS was provided built into ROM (either supplied with the external disk drive or in the machine ROM, depending on model) and was accessible through the built-in Locomotive BASIC as well as through firmware routines. Its main function was to map the cassette access routines (which were built into every CPC model) through to a disk drive. This enabled the majority of cassette-based programs to work with a disk drive with no modification. AMSDOS was able to support up to two connected disk drives. Commands AMDOS extends the AMSTRAD BASIC by the addition of a number of external commands which are identif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elektronika BK
The Electronika BK is a series of 16-bit PDP-11-compatible home computers developed under the Electronika brand by NPO Scientific Center, then the leading microcomputer design team in the Soviet Union. It is also the predecessor of the more powerful UKNC and DVK micros. Overview First released in 1984 (developed in 1983), they are based on the К1801ВМ1 (Soviet LSI-11-compatible CPU) and were the only ''official'' (government approved and accounted for in economic planning) Soviet home computer design in mass production. They sold for about 600–650 roubless. This was costly, but marginally affordable as the average Soviet monthly wage then was about 150 roubles. So they became one of the most popular home computer models in the Soviet Union. Later, in the 1990s, their powerful central processing unit (CPU) and straightforward, easy-to-program design made them popular as demoscene machines. ''BK'' (') is a Russian abbreviation for – domestic (or home) computer. The machines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CSI-DOS
CSI-DOS is an operating system, created in Samara, for the Soviet Elektronika BK-0011M and Elektronika BK-0011 microcomputers. CSI-DOS did not support the earlier BK-0010. CSI-DOS used its own unique file system and only supported a color graphics video mode. The system supported both hard and floppy drives as well as RAM disks in the computer's memory. It also included software to work with the AY-3-8910 and AY-3-8912 music co-processors, and the Covox Speech Thing. There are a number of games and demos designed specially for the system. The system also included a Turbo Vision-like application programming interface An application programming interface (API) is a way for two or more computer programs to communicate with each other. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how t ...

CP/M
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. 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. The combination of CP/M and S-100 bus computers became an early standard in the microcomputer industry. This computer platform was widely used in business through the late 1970s and into the mid-1980s. CP/M increased the market size for both hardware and software by greatly reducing the amount of programming required to install an application on a new manufacturer's computer. An important driver of software innovation was the advent of (comparatively) low-cost microcomputers running CP/M, as independent programmers and hackers bought them and shared their crea ...

Cromemco DOS
Cromemco DOS or CDOS (an abbreviation for Cromemco Disk Operating System) is a CP/M-like operating system by Cromemco designed to allow users of Cromemco microcomputer systems to create and manipulate disk files using symbolic names. Overview CDOS was written in Zilog Z80 machine code. Due to the number of available programs available to run under Digital Research CP/M at that time, CDOS was designed to be upwards CP/M-compatible. Many programs written for CP/M versions up to and including version 1.33 run without modification under CDOS. However, programs written for CDOS generally do not run under CP/M. The Cromemco Z-2 had the ability to run Cromemco DOS. Besides CP/M 2.2 and Cromix, the Cromemco System One can also run Cromemco DOS. The Cromemco C-10 personal computer, introduced in 1982, also ran CDOS. An emulator for a Cromemco CDOS system exists. Commands The following list of commands are supported by Cromemco DOS. Intrinsic commands * BYE * DIR * ERA * REN * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commodore DOS
Commodore DOS, also known as CBM DOS, is the disk operating system used with Commodore's 8-bit computers. Unlike most other DOSes, which are loaded from disk into the computer's own RAM and executed there, CBM DOS is executed internally in the drive: the DOS resides in ROM chips inside the drive, and is run there by one or more dedicated MOS 6502 family CPUs. Thus, data transfer between Commodore 8-bit computers and their disk drives more closely resembles a local area network connection than typical disk/host transfers. CBM DOS versions At least seven distinctly numbered versions of Commodore DOS are known to exist; the following list gives the version numbers and related disk drives. Unless otherwise noted, drives are 5¼-inch format. The "lp" code designates "low-profile" drives. Drives whose model number starts with 15 connect via Commodore's unique serial IEEE-488 bus (IEC Bus) serial (TALK/LISTEN) protocols; all others use the parallel IEEE-488. * 1.0 – fo ...

Atari 8-bit Family
The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 as the Atari 400 and Atari 800. The series was successively upgraded to Atari 1200XL , Atari 600XL, Atari 800XL, Atari 65XE, Atari 130XE, Atari 800XE, and Atari XEGS, the last discontinued in 1992. They differ primarily in packaging, each based on the MOS Technology 6502 central processing unit, CPU at and the same custom coprocessor chips. As the first home computer architecture with coprocessors, it has graphics and sound more advanced than most contemporary machines. Video games were a major draw, and first-person space combat simulator ''Star Raiders'' is considered the platform's killer app. The plug-and-play peripherals use the Atari SIO serial bus, with one developer eventually also co-patenting USB. While using the same internal technology, the Atari 800 was sold as a high-end model, while the 400 was more affordable. The 400 has a pressure-sensitive, spillproof membrane keyboar ...

Atari DOS
Atari DOS is the disk operating system used with the Atari 8-bit family of computers. Operating system extensions loaded into memory were required in order for an Atari computer to manage files stored on a disk drive. These extensions to the operating system added the disk handler and other file management features. The most important extension is the disk handler. In Atari DOS 2.0, this was the File Management System (FMS), an implementation of a file system loaded from a floppy disk. This meant at least an additional RAM was needed to run with DOS loaded. Versions There were several versions of Atari DOS available, with the first version released in 1979. Atari was using a w ...

Apple ProDOS
ProDOS is the name of two similar operating systems for the Apple II series of personal computers. The original ProDOS, renamed ProDOS 8 in version 1.2, is the last official operating system usable by all 8-bit Apple II series computers, and was distributed from 1983 to 1993. The other, ProDOS 16, was a stop-gap solution for the 16-bit Apple II that was replaced by GS/OS within two years. ProDOS was marketed by Apple as meaning Professional Disk Operating System, and became the most popular operating system for the Apple II series of computers 10 months after its release in January 1983. Background ProDOS was released to address shortcomings in the earlier Apple operating system (called simply DOS), which was beginning to show its age. Apple DOS only has built-in support for 5.25" floppy disks and requires patches to use peripheral devices such as hard disk drives and non-Disk-II floppy disk drives, including 3.5" floppy drives. ProDOS adds a standard method of accessing R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple II
The Apple II (stylized as ) is an 8-bit home computer and one of the world's first highly successful mass-produced microcomputer products. It was designed primarily by Steve Wozniak; Jerry Manock developed the design of Apple II's foam-molded plastic case, Rod Holt developed the switching power supply, while Steve Jobs's role in the design of the computer was limited to overseeing Jerry Manock's work on the plastic case. It was introduced by Jobs and Wozniak at the 1977 West Coast Computer Faire, and marks Apple's first launch of a personal computer aimed at a consumer market—branded toward American households rather than businessmen or computer hobbyists. ''Byte'' magazine referred to the Apple II, Commodore PET 2001, and TRS-80 as the "1977 Trinity". As the Apple II had the defining feature of being able to display color graphics, the Apple logo was redesigned to have a spectrum of colors. The Apple II is the first model in the Apple II series, followed by Apple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple DOS
Apple DOS is the family of disk operating systems for the Apple II series of microcomputers from late 1978 through early 1983. It was superseded by ProDOS in 1983. Apple DOS has three major releases: DOS 3.1, DOS 3.2, and DOS 3.3; each one of these three releases was followed by a second, minor "bug-fix" release, but only in the case of Apple DOS 3.2 did that minor release receive its own version number, Apple DOS 3.2.1. The best-known and most-used version is Apple DOS 3.3 in the 1980 and 1983 releases. Prior to the release of Apple DOS 3.1, Apple users had to rely on audio cassette tapes for data storage and retrieval. Version history When Apple Computer introduced the Apple II in April 1977, the new computer had no disk drive or disk operating system (DOS). Although Apple co-founder Steve Wozniak designed the Disk II controller late that year, and believed that he could have written a DOS, his co-founder Steve Jobs decided to outsource the task. The company considered using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
