Now this was very much a worthy sucessor to the 80 machines, carried all the best feature and added to it, had a decent keyboard and had a rarity feature (amongst home computers) of a fairly sharp drift free picture (the fact it, via RF modulator, had a high signal output helped no end, and if you had the pleasure of using it with a CV monitor, sharp as f\*ck). Sure, whilst there was a fair $ion of software (outside of the programming language cassettes), most never appeared in the UK via the sole supplier (Sharpsoft, in London). But, unlike many computers in the day, it came with a pretty comprehensive reference data set in the manual, so it acually encouraged you to tinker with assembly coding. In fact, my exam project for school was rapidly migrated from it''s assembler version developed on a ZX81 to the MZ721. Of course, accessories were like hen''s teeth, but because it came with such good documentation, it wasn''t rocket science to build your own controllers for gaming and other uses. I can remember how people laughed at the fact you had to load up Basic (or other interpreters), but it was no big deal - as a wise, older family friend passed on to me, all he did was start it loading, go make a cup of tea and by the time you carried it back to your desk, it was loaded ... Painless choice, for those who''s idea of home computing wasn''t spoon-fed endless commercial cassettes fair. Oh, i almost forgot - mine got overclocked as part of my experiments... to a massive (back in the day) 16 Mhz, but that did involve some serious modding to make it happen - it taught me the value of inherent limits and that heatsinks were essential parts of a modding tinker demon''s kit. - author: Tom (Israel) date: Sunday 23rd July 2017 text: |- Hi\ As a young child we had a mz700 at home, today i enjoy loading the roms on my computer and see the difference between what i remember and how it is in reality :) Can anyone help, i remember a game that you needed to manage or control a newspaper company\ I might be wrong here, I don''t think we really understand what it really was but that''s the best i can tell.

I know we had a Sharp and it was in the early 80ies. It had a built in tape drive and it looked a lot like this one. I never learned how to program it though. Mostly because I wasn''t very good at English at the time, so I don''t think I ever read the manual. It came with some rather interesting games though. I eventually replaced it with a Commodore 64. Because that''s what my friends had. The Sharp might have been a better computer however. - author: darren morris (United Kingdom) date: Wednesday 29th December 2010 text: This is Classic Computing....and i have still got a Sharp MZ 700 and Monitor of working order in my roof space..The printer still works but after 27 years its got a dry... - author: adam date: Thursday 2nd December 2010 text: i parents brought one of these computer for me and my brothers my grandparents were not happy about it because there own commodores 64 anyway i enjoy much more because i learn how to program in basic and yes the games were not great but here i enjoy clocking snake every time - author: John Whitworth date: Sunday 4th July 2010 text: 'Re: Christopher Davies not wanting to press EXEC - it reminds me of my friend and I, typing in a game from a magazine on his BBC.

Still working ! - author: Miguel (Málaga) date: Friday 19th August 2005 text: It was my second computer after a couple of years using a ZX81. I enjoyed it a lot and spent hundreds of hours on it. I learned BASIC, PASCAL, FORTH and FOTRAN using my Mz-731. I remember I made some programs based on Scientific American articles. The best one was to represent and move an hypercube using the plotter to render the hypercube in red & blue (one eye each) and using a red-blue glasses you could see it in 3D. I have just tryed it today after 20 years and it still works. Unfortunately my programs tape is lost. - author: Christian Müller (Germany) date: Thursday 2nd December 2004 text: |- The Sharp MZ-731 was the first computer I ever got my hands on. My dad bought one in 1983 when I was 6. I was fascinated by the games and always wanted to write one myself.\ In the summer break after 2nd form I started reading the BASIC manual and trying my hands at coding. Now I'm 28 and studying Information Theory and Electronics in the 10th semester. I'm going for the finals this year. If my dad hadn't bought that computer when I was little who knows if I ever got interested in computers at all. - author: Justin Little (Australia) date: Sunday 2nd March 2003 text: I wanted a C64 but I got a Sharp MZ-721 and I loved it. I learned how to make my own programs in basic. Got a printer plotter for my next birthday. I spent hours on this computer. I spent a lot of time finding Pokes that would give me advantages in games. I got a better Basic tape that gave lots of extra commands. It was fun. Then the Commodore 128D came out cheap. So my MZ went into storage, sold it at a garge sale in 2000 for Aus$40. - author: Cucal (Teruel) date: Monday 28th October 2002 text: |- Este cacharrito fué mi iniciacion a los ordenadores.\ Mientras todos tenian Amstrad y/o spectrum, yo tenia esto, lo que hizo que tuviera que generar mis propios juegos.

Moreover, the MZ 700 was compatible with the MZ 80K and MZ 80A. The MZ 700 series is composed of four machines: the first three models were launched in 1983 (November 1982 in Japan) and the last one was launched in late 1985 (in fact, this one is the "ancestor" of the MZ 800): \- the **MZ 711** was the "naked" model (without any peripheral),\ \- the **MZ 721**, has an integrated tape recorder\ \- the **MZ 731**, has built-in plotter and tape recorder).\ \- the fourth model was the **MZ 780** which was actually a MZ 731 with a 80 columns card, a floppy disk drive and a Centronics port. It worked under CP/M. There was no language in ROM (the ROM size is only 2 KB, it is just used for boot and OS calls), it has to be loaded from tape. So there was a lot of languages adapted for this machine (more than five versions of BASIC, assemblers, Pascal, Lisp, C, Fortran, Comal, Forth, & others). The games were a bit poor because of the low resolution (which was actually graphical characters), but there were 512 graphic characters in ROM, which can be used to offset it (sort of). It will be replaced with the [MZ 800](/museum/sharp-mz-800-mz-1500/).
