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.

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).
