The Sharp MZ is a series of personal computers sold in Japan and Europe (particularly Germany and Great Britain) by Sharp beginning in 1978.
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 , [1] 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 era when floppy disk drives were too expensive for most home users, the MZ's built-in cassette tape drive was faster and more reliable than the cassette storage on some competing computers; [2] however, this meant that the MZ series was relatively slow to adopt floppy drives as a standard accessory.
In 1983, after the most popular home computers appeared in the UK, the Sharp MZ-700 was briefly the 10th best selling machine out of 20 considered, beating the Apple IIe, Atari 800 and TI-99/4A. [3]
In May 2012, Sharp's Japanese Twitter account announced that they had found a copy of an MZ manual in a warehouse, and were hoping to digitize it in the future. [4] On 21 December 2012, Sharp's Japanese Twitter account announced [5] [6] [7] that they had published digital copies of manuals for the MZ-80 on their official website. [8] [9] It was promoted as a "Christmas present" to fans. [10]
The MZ series is divided into several lines, including the text-based MZ-80K series, the graphics-based MZ-80B series, and the MZ-3500/5500 series, based on a completely different architecture.
In 1982, Sharp's television division released the X1, a completely new computer. The X series proved to outsell Sharp's own MZ series, and in response, Sharp released the MZ-1500/2500 machines, which featured powered-up graphics and sound capabilities. However, this series saw little marketplace success, and eventually the company abandoned the line in favor of the X68000 series.
The Sharp MZ-80K was one of the popular early consumer-level microcomputers, with an architecture based on the Zilog Z80 8-bit microprocessor. It was introduced into Europe in 1979. The machine had 48KB of RAM, 32KB of which was available for user programs (the actual figure was dependent on the memory configuration and the system languages being used). It could run a variety of high-level languages including BASIC, Pascal and FORTRAN, which had to be loaded into RAM before any programming could be undertaken. It could also be programmed directly in assembly code or machine code. The machine had an inbuilt monochrome display and a cassette tape drive. The display, keyboard and cassette drive lifted on hinges to expose the motherboard and circuitry underneath. Graphics capability was primitive, with only preset shapes and icons being available and no native hi-res capability. This was not unusual for a late-1970s vintage microcomputer. The main drawback, however, of the MZ-80K was the non-standard keyboard, which was difficult to use.
The MZ-80K sold well in Europe despite its high price (it retailed at over £500 in 1980), and a large range of software was available, including some Japanese arcade games. It was superseded in 1982 by the MZ-80A machine.
This offshoot of the MZ-80K line was primarily marketed for business use.
A line of business PCs shoehorned into the MZ lineup. All of them feature 5.25-inch floppy disk drives.
Amstrad was a British consumer electronics company, founded in 1968 by Alan Sugar. During the 1980s, the company was known for its home computers beginning with the Amstrad CPC and later also the ZX Spectrum range after the Sinclair deal, which led it to have a substantial share of the PC 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, which Amstrad had started in 1989 as the then sole supplier of the emerging Sky TV service.
The Tandy 1000 was the first in a series of IBM PC compatible home computers produced by the Tandy Corporation, sold through its Radio Shack and Radio Shack Computer Center stores. Introduced in 1984, the Tandy 1000 line was designed to offer affordable yet capable systems for home computing and education. Tandy-specific features, such as enhanced graphics, sound, and a built-in joystick port, made the computers particularly attractive for home use.
MSX is a standardized home computer architecture, announced by ASCII Corporation on June 16, 1983. It was initially conceived by Microsoft as a product for the Eastern sector, and jointly marketed by Kazuhiko Nishi, the director at ASCII Corporation. Microsoft and Nishi conceived the project as an attempt to create unified standards among various home computing system manufacturers of the period, in the same fashion as the VHS standard for home video tape machines. The first MSX computer sold to the public was a Mitsubishi ML-8000, released on October 21, 1983, thus marking its official release date.
The Amstrad PCW series is a range of personal computers produced by British company Amstrad from 1985 to 1998, and also sold under licence in Europe as the "Joyce" by the German electronics company Schneider in the early years of the series' life. The PCW, short for Personal Computer Word-processor, was targeted at the word processing and home office markets. When it was launched the cost of a PCW system was under 25% of the cost of almost all IBM-compatible PC systems in the UK, and as a result the machine was very popular both in the UK and in Europe, persuading many technophobes to venture into using computers. The series is reported to have sold 8 million units. However the last two models, introduced in the mid-1990s, were commercial failures, being squeezed out of the market by the falling prices, greater capabilities and wider range of software for IBM-compatible PCs.
The IBM Personal Computer AT was released in 1984 as the fourth model in the IBM Personal Computer line, following the IBM PC/XT and its IBM Portable PC variant. It was designed around the Intel 80286 microprocessor.
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 Intel 8088 processor, and the IBM PC/AT would later use the newer 6 MHz Intel 80286. Due to the 16-bit 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 Zilog Z80 and Motorola 6809 CPUs.
The Amstrad PC1512 was Amstrad's mostly IBM PC-compatible computer system, launched in 1986, and advertised with prices from £399 plus VAT. The system was also marketed in the US by Texas-based Vidco Inc. from the start of 1987. Later in 1987, a slightly updated version called the PC1640 was introduced, also marketed as the PC6400 and Sinclair PC500. Schneider branded machines for the German market were also sold.
The X68000 is a home computer created by Sharp Corporation. It was first released in 1987 and sold only in Japan.
The Rainbow 100 is a microcomputer introduced by Digital Equipment Corporation (DEC) in 1982. This desktop unit had a monitor similar to the VT220 and a dual-CPU box with both 4 MHz Zilog Z80 and 4.81 MHz Intel 8088 CPUs. The Rainbow 100 was a triple-use machine: VT100 mode, 8-bit CP/M mode, and CP/M-86 or MS-DOS mode using the 8088. It ultimately failed to succeed in the marketplace which became dominated by the simpler IBM PC and its clones which established the industry standard as compatibility with CP/M became less important than IBM PC compatibility. Writer David Ahl called it a disastrous foray into the personal computer market. The Rainbow was launched along with the similarly packaged DEC Professional and DECmate II which were also not successful. The failure of DEC to gain a significant foothold in the high-volume PC market would be the beginning of the end of the computer hardware industry in New England, as nearly all computer companies located there were focused on minicomputers for large organizations, from DEC to Data General, Wang, Prime, Computervision, Honeywell, and Symbolics Inc.
Micro-Professor II (MPF-II) is an Apple II clone introduced in 1982 by Multitech. It is Multitech second branded computer product and also one of the earliest Apple II clones. The MPF II doesn't look like most other computers, with its case being a slab with a small chiclet keyboard on the lower part.
The PC-6000 series is a series of 8-bit home computers introduced in November 1981 by NEC Home Electronics. There are several models in this series, such as the PC-6001, the PC-6001 MK2 and the PC-6001 MK2 SR. There is also an American version, called the NEC TREK or NEC PC-6001A.
The PC-8000 series is a line of personal computers developed for the Japanese market by NEC. The PC-8001 model was also sold in the United States and Canada as the PC-8001A.
Music Macro Language (MML) is a music description language used in sequencing music on computer and video game systems.
The Sharp PC-1600 was a pocket computer introduced by Sharp in 1986 as a successor to the PC-1500. The PC-1600 provided compatibility with its predecessor through the use of a slave CPU that could run assembly language programs targeting the older machine. It could also switch into a compatibility mode so that programs written for the single line display of the PC-1500 could work with the four line display of the PC-1600.
The Commodore PC compatible systems are a range of IBM PC compatible personal computers introduced in 1984 by home computer manufacturer Commodore Business Machines.
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".
The P8000 is a microcomputer system developed in 1987 by the VEB Elektro-Apparate-Werke Berlin-Treptow „Friedrich Ebert“ (EAW) in the German Democratic Republic. It consisted of an 8-bit and a 16-bit microprocessor and a Winchester disk controller. It was intended as a universal programming and development system for multi-user/multi-task applications. The initial list price of the P8000 was 172,125 East German marks.
Sharp MZ character sets are character sets made by Sharp Corporation for Sharp MZ computers. The European and Japanese versions of the software use different character sets.
The MZ-2500, also known as the Super MZ, is an 8-bit personal computer released on 1 October 1985 as part of the Sharp MZ series. It is a successor to the MZ-2000/2200 and a direct successor to the MZ-80B from the previous generation. The MZ-2000 was a model that was given significant functions, along with a faster processing speed. It is also the final model of the entire 8-bit MZ series with architecture of its kind. It is sometimes referred to as the best 8-bit machine along with the 6809 FM77AV and the MB-S1. In Japanese computer magazines, the MZ-2500 was also called 'The Phoenix'. Its successor was the Sharp MZ-2861 which has a compatible mode and a newly developed 16-bit mode. The development code is LEY and can be found in the circuit diagram.
