IS-DOS
iS-DOS is a disk operating system (DOS) for Soviet/Russian ZX Spectrum clones. iS-DOS was developed in 1990 or 1991, by Iskra Soft, in Leningrad, Soviet Union, now Saint Petersburg, Russia. It handles floppy disks (double sided, double density), hard disk drives, and CD-ROMs. Maximum iS-DOS disk partitioning size on a hard disk is 16 MiB. Unlike TR-DOS, iS-DOS is resident in random-access memory (RAM), and thus reduces the amount of memory available for user programs. Versions ''iS-DOS Chic'' is a version developed for the Nemo KAY. It provides more memory for user programs. ''TASiS'', based on iS-DOS Chic, is a modern version developed by NedoPC for the ATM Turbo 2+ in 2006, supports the enhanced text mode and larger memory of that model. Distributors * Slot Ltd. (Moscow) distributed iS-DOS in Moscow and regions in 1990s, and issued paper books. * Nemo (Saint Petersburg) distributed iS-DOS in ex-USSR until 2004, and issued ''Open Letters'' electronic press. * iS-DOS ...

Scorpion ZS-256
The Scorpion ZS-256 was a very widespread ZX Spectrum clone produced in St. Petersburg by Sergey Zonov (same person behind the "Leningrad" clone). Introduced in 1991, it was fitted with a Zilog Z80B processor, a AY-3-8910 sound chip, whilst RAM memory options ranged from 256 to 1024 KB. The computer was usually assembled in a mini tower configuration with a standard IBM power supply, allowing the connection of peripherals, drives, etc. Various expansions were produced, including ''SMUC'' – an adapter for IDE and ISA slots, which allowed the use of IBM PC compatible hard drives and expansion cards. The Shadow Service Monitor (debugger) in the BASIC ROM was activated by pressing the Magic Button (NMI). There was also the option of fitting the machine with a ''ProfROM'' which included such software as a clock, hard disk utilities, and the ''ZX-Word'' text editor. The computer can work with TR-DOS, CP/M and IS-DOS systems. In 1996, the Scorpion ZS-256 Turbo+ version ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kay 1024
The Kay 1024 was a Russian ZX Spectrum clone introduced in 1998. Created by the NEMO company of St. Petersburg, it has 1024 KB of RAM. It was a rival to Scorpion ZS 256, having a slightly lower price. It offered a controller for a PC keyboard and HDD, but not for floppy disks (although available as an extension card). Adding a General Sound card was easy, and the CPU had a 7 Mhz turbo mode. Earlier versions of the machine were known as Kay 128 and Kay 256. The Kay 2006 NB (North Bridge) is a 2006 version based on the Altera EPM7064 MAX. It adds three new graphics modes: Multicolor, GigaScreen and 512×192 pixels in 2 colors. The Kay 2010 or Kay 1024/SL4 is a 2010 update of the original KAY 1024 with a few minor additions and improvements. The Kay 2010 mainboards are manufactured in Chelyabinsk. Specifications Brief technical specifications of KAY-1024 computer: * Supplied as a complete board, with a IS-DOS floppy disk, drivers and utilities, a ribbon cable and instru ...

Proprietary Software
Proprietary software is software that is deemed within the free and open-source software to be non-free because its creator, publisher, or other rightsholder or rightsholder partner exercises a legal monopoly afforded by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting his or her freedoms. It is often contrasted with open-source or free software. For this reason, it is also known as non-free software or closed-source software. Types Origin Until the late 1960s computers—large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than sold. Service and all software available were usually supplied by manufacturers without separate charge until 1969. Computer vendors ...

Microcomputer Software
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). An early use of the term ''personal computer'' in 1962 predates microprocessor-based designs. ''(See "Personal Computer: Computers at Companies" reference below)''. A ''microcomputer'' used as an embedded control system may have no human-readable input a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Freeware
Freeware is software, most often proprietary, that is distributed at no monetary cost to the end user. There is no agreed-upon set of rights, license, or EULA that defines ''freeware'' unambiguously; every publisher defines its own rules for the freeware it offers. For instance, modification, redistribution by third parties, and reverse engineering are permitted by some publishers but prohibited by others. Unlike with free and open-source software, which are also often distributed free of charge, the source code for freeware is typically not made available. Freeware may be intended to benefit its producer by, for example, encouraging sales of a more capable version, as in the freemium and shareware business models. History The term ''freeware'' was coined in 1982 by Andrew Fluegelman, who wanted to sell PC-Talk, the communications application he had created, outside of commercial distribution channels. Fluegelman distributed the program via a process now termed '' shareware''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
