KEYBOARD CLOSE-UP Notice the MZ logo that will be used in all of the computers of the MZ series. About this logo, MZ 80K user manual says: From ancient times people have been fascinated by the lights from outer space.\ That's why through times people would have the lad in Greek mythology dreamt of lights spreading over the vistas of space.\ Then he sailed for the Golden Fleece, aiming at a bright future. Indeed, Argo Navis is such a constellation clearly shining over the horizon in the south. This constellation is symbolized by the ship sailing with youth; the ship representing courage, future, search and longing.\ Just like the ship of youth, the MZ 80K will sail before long. To realize your dreams in such a manner, we have created this Sharp's original mark. /media/museum/photos/sharp_mz80k_keybcloseup_1.jpg

IO EXPANSION BOX - VIEW #1 The MZ 80K has only one bus extension. To remedy to this problem, Sharp developped the MZ80 I/O Port device. This heavy device can support up to five boards (floppy controller, EPROM programmer, Centronics, etc...). A parallel interface was developped by Sharp to use the Seikosha printers. /media/museum/hardware/sharp_mz80k_iobox.jpg

FRENCH FDD UNIT Instead of selling the original Sharp FDD unit, the Sharp French subsidiary (Sharp Burotype Machines) preferred to made their own unit. The case could hold up to 4 drives. The drives were Canon models. /media/museum/hardware/sharp_mz80b_frenchfdd_s1.jpg

The MZ-80K was, alongside the Apple II, the Commodore PET and the Tandy TRS 80’s one of the best known computer in the early 80's. Its name stands for "M" from MICRO and Z-80 from the computer it uses.

It has no language in ROM, and BASIC has to be loaded from tape. Sharp called this "clean design", as you could choose what you wanted to put in your computer, the MZ-80K being delivered clean... Though a 5.25" floppy disk unit was later available, most people never used anything else than the built-in tape recorder (1200 bps).

There is no colour, no high resolution and characters sets can't be redefined. But the pre-defined characters set was very complete offering a lot of different graphical symbols, and people (mainly japanese) created great games, overcoming the main flaw of the MZ-80 serie... A graphic card was later designed for this computer, allowing to redefine the characters set resulting in a virtual "high resolution" of 320 x 192 pixels.

The MZ-80K is equiped with a real clock and a built-in speaker.

First MZ-80K were sold in Japan as assembly kits (1978). In 1980, Sharp released the MZ-80K2 which is basicaly a MZ-80K with 32 KB RAM, a non-reflective keyboard and and a volume control at the rear of the system. One year later, a cost reduced version, the MZ-80K2e, was marketed as an anniversay model when MZ serie sales reached one hundred thousand machines.
