The Sharp MZ 700 series replaced the aging MZ 80 (MZ 80K, MZ 80A and MZ 80B) series. 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.

The newspaper game for the MZ-700 was called Scoop and it was by Solo Software that wrote all of their commercial games in BASIC.

The MZ-721 was my follow-up to owning a highly modified ZX81 (or as it was better known as ''the Sinclair Beirut'' due the extreme cooling mods).
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.
