Disk Operating System
A disk operating system (DOS) is a computer operating system that requires a disk or other direct-access storage device as secondary storage. A DOS provides a file system and a means for loading and running computer program, programs stored on the disk. The term is now historical, as most if not all operating systems for general-purpose computers now require direct-access storage devices as secondary storage. History Before modern storage such as the disk drive, floppy disk, and flash storage, early computers used storage such as Analog delay line, delay line, core memory, punched card, punched tape, magnetic tape, and magnetic drum. Early microcomputers and home computers used paper tape, audio cassette tape (such as Kansas City standard), or no permanent storage at all. Without permanent storage, programs and data are input directly into memory using front panel switches, or is input through a computer terminal or keyboard, sometimes controlled by a BASIC interpreter in read-on ...

DOS XL
DOS XL is a discontinued Disk Operating System (DOS) written by Paul Laughton, Mark Rose, Bill Wilkinson, and Mike Peters and published by Optimized Systems Software (OSS) for the Atari 8-bit computers. It was designed to be compatible with Atari DOS which shipped with Atari, Inc.'s disk drives, which had also been written by the same team. Description Features A direct descendant of OS/A+, DOS XL provided additional features to Atari's equipped with floppy disk drives. These included single and double density support, a command-line mode (called the command processor or CP), a menu mode (an executable loaded in memory), batch file support, and support for XL extended memory and OSS SuperCartridge banked memory. Later versions included Axlon RamDisk support, Mosaic RamDisk support, BIT-3 support and BUG/65. In addition to supporting auto-booting AUTORUN.SYS files, DOS XL's batch features provided an auto-booting batch feature. Naming a batch file to STARTUP.EXC would have it e ...

Apple DOS
Apple DOS is the disk operating system for the Apple II computers 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 It was superseded by ProDOS in 1983.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 Digital Research's CP/M, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronika BK
The Electronika BK is a series of 16-bit computing, 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 1985 (developed in 1983), they are based on the К1801ВМ1 (Soviet PDP-11#LSI-11, 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 Soviet rouble, roubles. This was costly, as the average Soviet monthly wage then was about 150 roubles. Despite their cost, 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 language, Russian abbrevia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ANDOS
ANDOS is a Russian operating system for Electronika BK series computers: BK-0010, BK-0011, and BK-0011M. They were based on the PDP-11 architecture by Digital Equipment Corporation. ANDOS was created in 1990 and released first in 1992. Initially it was developed by Alexey Nadezhin (by whose name the system is named) and later also by Sergey Kamnev, who joined the project. It was the only widespread system on BK series computers that used MS-DOS-compatible file system format. ANDOS used the FAT12 file system on 800 Kb floppy disks. For Electronika BK-0011M and BK-0011, ANDOS could emulate a BK-0010 by loading a BK-0010 read-only memory (ROM) image into BK-0011(M) random-access memory (RAM). In minimal configuration, the system could occupy less than 4 Kb of RAM. The system was able to support up to 64 disk drives (or hard disk drive partitions), and RAM disk A RAM drive (also called a RAM disk) is a block of random-access memory ( primary storage or volatile memory ...

Amstrad
Amstrad plc was a British consumer electronics company, founded in 1968 by Alan Sugar. During the 1980s, the company was known for its Home computer, home computers beginning with the Amstrad CPC and later also the ZX Spectrum range after the Sinclair Research, Sinclair deal, which led it to have a substantial share of the home computer market in Britain. In the following decade it shifted focus towards communication technologies, and its main business during the 2000s was the manufacture of satellite television set-top boxes for Sky UK, Sky, which Amstrad had started in 1989 as the then sole supplier of the emerging Sky TV service. Headquartered in Brentwood, Essex, Brentwood, the company was listed on the London Stock Exchange from 1980 to 2008, the year when Sugar stepped down after 40 years. After acquiring Betacom and Viglen, Amstrad was broken up in 1997 but the name was soon revived when successor Betacom plc renamed itself to Amstrad plc. Amstrad was a FTSE 100 Index co ...

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 identi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AmigaOS
AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola Motorola 68000 family, 68000 series of 16-bit and 32-bit microprocessors. Later versions, after Commodore's demise, were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). A PowerPC microprocessor is required for the most recent AmigaOS 4-release. AmigaOS is a single-user operating system based on a preemptive multitasking kernel (operating system), kernel, called Exec (Amiga), Exec. It includes an abstraction of the Amiga's hardware, a disk operating system called ''AmigaDOS'', a windowing system Application programming interface, API called Intuition (Amiga), ''Intuition'', and a desktop environment and file manager called Workbench (AmigaOS), ''Workbenc ...

AmigaDOS
AmigaDOS is the disk operating system of the AmigaOS, which includes file systems, file and directory manipulation, the command-line interface, and file Redirection (computing), redirection. In AmigaOS 1.x, AmigaDOS is based on a TRIPOS port by MetaComCo, written in BCPL. BCPL does not use native pointer (computer programming), pointers, so the more advanced functionality of the operating system was difficult to use and error-prone. The third-party ''AmigaDOS Resource Project'' (ARP, formerly the ''AmigaDOS Replacement Project''), a project begun by Amiga developer Charlie Heath, replaced many of the BCPL utilities with smaller, more sophisticated equivalents written in C (programming language), C and assembly language, assembler, and provided a wrapper library, arp.library. This eliminated the interfacing problems in applications by automatically performing conversions from native pointers (such as those used by C or assembler) to BCPL equivalents and vice versa for all AmigaDOS ...

Turbo-DOS
Atari DOS is the disk operating system used with the Atari 8-bit 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 cross assembler with Data General AOS. DOS 1.0 In the first version of DOS from Atari, all commands were only accessible from the menu. It was bundled with the Atari 810 disk drives. This version was entirely memory resident, which made it fast but occupied memory space. DOS 2.0 :Also known as ''DISK OPERA ...

SpartaDOS X
SpartaDOS X (or SpartaDOS 4.0) is a disk operating system for the Atari 8-bit computers that closely resembles MS-DOS. It was developed and sold by ICD in 1987-1993, and many years later picked up by the third-party community SpartaDOS X Upgrade Project, which still maintains the software. History SpartaDOS X is a successor to SpartaDOS 1.0, 2.0 and 3.0 (also ICD products) and while it enjoys good level of backward compatibility with older versions, it is a completely new system, written from scratch. SpartaDOS X 4.0 was originally developed by Michael Gustafson in 1987-89,Atari 8-bit FAQ http://faqs.cs.uu.nl/na-dir/atari-8-bit/faq.html and shipped on 64k ROM cartridges by ICD, Inc. up to version 4.21. The cartridge contained an additional cartridge slot on itself, so that it was possible to plug-in another cartridge, such as ICD's R-Time 8 battery-backed clock, a language cartridge ( Action!, MAC/65 etc.) or a game cartridge, and use it in conjunction with the DOS.
