MZ 80K

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.

I am sitting in my office coding in .net and the like, and on my right is my Sharp MZ-80K that started it all! And it has a hi-res graphics card :-o

Like others, it was my first computer. My dad bought it for me, as I was a sickly child with really bad asthma and eczema and he thought that an active life-style wouldn’t be an option (he was wrong by the way).

I remember the Orange BASIC book that came with it, which I trawled through again and again to learn how to use this new machine. There was a TRON light-cycle like game in there over several pages called something like “Mr Smith and Mr Jones”, which I laboriously typed in with 1 finger. I remember being very upset when I accidentally cleared the screen and I thought I’d lost it all. That’s when I discovered the LIST command :-)

Though it looked like a Norse ship it was in fact meant to represent the Argo and thus a voyage of discovery.

If one sees the MZ80K M/C or Assembler Manuals the ship is larger and the figures on it can be seen to be Greek, also it is accompanied by a map indicating

oh and what''s this just beneath the Argo

P.S. Did anyone work out what the whole Norse Viking ship thing was about on all the manuals and software and branding?

That still puzzles me to this day....why?
