The Sharp MZ-800 was the successor of the MZ-780. It was partially compatible with the 700 series and the old MZ-80K series as well. The Tape drive could be substituted for a Quick-disk drive unit. The Quick-Disc was a small 2.8-inch disk with sequential access.
Like the MZ-700, there was no language in ROM, it had to be loaded from tape, quick disk or floppy disk. The ROM only contained boot code, OS calls and special code to allow the user to use the 64 KB RAM as a virtual disk.
A single or double 5.25" disk drive could be connected to the MZ-800. It then worked under a special version of CP/M called P-CP/M. Some great products like Wordstar, dBase II and Multiplan were adapted to it. Under CP/M, it was possible to read multiple disk formats from the 360 KB (Sharp format) to the 720 KB (CP/M IBM PC format).
