Trivia
The Sharp MZ-800 is an upgrade to the Sharp MZ-700. The upgrade mainly consists of a better graphics mode, better sound, a reset button and more I/O ports.
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).
