The Sharp MZ is a series of personal computers sold in Japan and Europe (particularly Germany and Great Britain) by Sharp beginning in 1978.

Overview

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 1980. This was soon followed by the MZ-80K, K2, C, and K2E, all of which were based on Fujitsu's 4-bit MB8843 processor and provided a simple hexadecimal keypad for input. (The MZ-80C, which was sold fully assembled, included a full 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, like the IBM PC. This allowed 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 tape drive was considered faster and more reliable than the drive on competing computers; however, this meant that the MZ series was relatively slow to adopt floppy drives as a standard accessory.

Product Line

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 MZ name lives on as the initials of two of Sharp's most well-known products: the Mebius line of PCs, and the Zaurus line of personal digital assistants.

MZ-80K group

This group of machines was based off the original MZ-40 computer kit.

MZ-80K series
* MZ-80K (1978) - An all-in-one kit with keyboard.
* MZ-80C - Featured an improved keyboard and 48KB of memory.
* MZ-80K2 - The assembled version of the 80K.
* MZ-80K2E - A low-price version of the 80K2.
* MZ-80A/MZ-1200 - A slightly upgraded version of the 80K.

MZ-700 series (MZ-80K machines with color graphics）
* MZ-700 (1982) - The first MZ without a built-in monitor; an optional data recorder and plotter could also be installed to the machine. More-or-less fully compatible with the MZ-80K.
* MZ-800 (1985) - The first MZ with a 640x200-pixel graphics mode. Not available in Japan.
* MZ-1500 (1984) - Features 320x200-pixel graphics and built-in sound capability. The tape recorder has been replaced with a floppy drive that reads three-inch Quick Disks.

MZ-80B group

This offshoot of the MZ-80K line was primarily marketed for business use.

MZ-80B series
* MZ-80B (1981) - 320x200-pixel graphics. (Extra VRAM optional)
* MZ-80B2 - An 80B with extra VRAM installed. Sold alongside the MZ-2000 for most of the lineup's lifetime.
* MZ-2000 (1982) - 640x200-pixel monochrome monitor built-in; color optional. BASIC-level compatible with the MZ-80B.
* MZ-2200 (1983) - The only monitorless, standalone unit in the series.

MZ-2500 (SuperMZ) series - Launched in 1985, the computers in this series all used a Z80B processor running at 6MHz. They included a data recorder and at least one 3.5 internal floppy disk drive, as well as a YM2203 FM sound chip, hardware scrolling, and a palette of 256 colors (upgradable to 4096). This makes them among the most powerful 8-bit machines ever released for home use. Some models are also compatible with the MZ-80B and MZ-2000.
* MZ-2511
* MZ-2520 - The 2511 without a data recorder and the MZ-80B/2000 compatibility modes.
* MZ-2521
* MZ-2531(MZ-2500V2) (1986)

MZ-2800 series
* MZ-2861 (1987) - A hybrid 16-bit machine running on an Intel 80286 and a Z80 for MZ-2500 compatibility. It could run MS-DOS
in 16-bit mode, as well as a PC98 emulator.

MZ-3500/5500/6500 group

A line of business PCs shoehorned into the MZ lineup. All of them feature 5.25-inch floppy disk drives.

MZ-3500 (1982) - Runs on two Z80A processors.
MZ-5500 series (1983) - An MS-DOS
-based machine running on an Intel 8086 processor.
MZ-6500 series (1984) - A high-speed version of the MZ-5500 marketed as a CAD workstation.
* MZ-6500
* MZ-6550 - A vertically-mounted machine with an 80286 processor and a 3.5-inch floppy drive.
