S-OS
S-OS is a simple operating system mainly for Z80 based computers. The operating system was first presented in 1986 in the Japanese magazine Oh!X in an article called "The Sentinel". Commands The command and command set is very simplified. :Directory ''#D :">device name>:' :Change default device (S=startup, A=tape..) ''#DV :'' :Jump to address (and run program) ''#J '' :Load the program ''#L ' :Enter the machine specific monitor ''#M'' :Delete the file ''#K '' :Save a memory block to file ''#S : : ' :Exit from S-OS and reboot ''#!''

Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...

Sharp MZ
The Sharp MZ is a series of personal computers sold in Japan and Europe (particularly Germany and Great Britain) by Sharp beginning in 1978. History Although commonly believed to stand for "Microcomputer Z80", the term MZ actually has its roots in the MZ-40K, a home computer kit produced by Sharp in 1978 which was based on Fujitsu's 4-bit MB8843 processor and provided a simple hexadecimal keypad for input. This was soon followed by the MZ-80K, K2, C, and K2E, all of which were based on 8-bit LH0080A Sharp CPU (compatible to Zilog Z80A) with an alphanumeric keyboard. From the first Z80 processor-based model to the MZ-2200 in 1983, the MZ computers included the PC, monitor, keyboard, and tape-based recorder in a single unit, similar to Commodore's PET series. It was also notable for not including a programming language or operating system in ROM. This invited a host of third-party companies, starting with Hudson Soft, to produce many languages and OSes for the system. In an ...

Sharp X1
The , sometimes called the Sharp X1 or CZ-800C, is a series of home computers released by Sharp Corporation from 1982 to 1988. It is based on a Zilog Z80 CPU. The RGB display monitor for the X1 had a television tuner, and a computer screen could be super-imposed on TV. All the TV functions could be controlled from a computer program. The character font was completely programmable (PCG) with 4-bit color, and was effectively used in many games. The entirety of the VRAM memory was mapped on to the I/O area, so it was controlled without bank switching. These features made the X1 very powerful for game software. Development Despite the fact that the ''Computer Division'' of Sharp Corporation had released the MZ series, suddenly the ''Television Division'' released a new computer series called the X1. At the time the original X1 was released, all other home computers generally had a BASIC language in ROM. However the X1 did not have a BASIC ROM, and it had to load the Hu-BASIC ...

Sharp X68000
The is a home computer created by Sharp Corporation. It was first released in 1987 and sold only in Japan. The initial model has a 10 MHz Motorola 68000 CPU, 1 MB of RAM, and lacks a hard drive. The final model was released in 1993 with a 25 MHz Motorola 68030 CPU, 4 MB of RAM, and optional 80 MB SCSI hard drive. RAM in these systems is expandable to 12 MB, though most games and applications do not require more than 2 MB. The X68000 has graphics hardware similar to arcade video games of the late-1980s, with custom coprocessors supporting scrolling, tiled backgrounds, and large numbers of sprites. There are multiple sound chips supporting 8 channels of FM synthesis; 2 channels of stereo, digital audio; and one channel of pulse-code modulation audio. As such, video gaming was a major use of the X68000. Operating system The X68k runs an operating system called Human68k which was developed for Sharp by Hudson Soft. An MS-DOS-workalike, Human68k features English- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
