System Information

 

MZ700 Series
The Sharp MZ 700 serie replaces the old serie of MZ 80 (MZ 80K, MZ 80A and MZ 80B). Moreover, the MZ 700 is compatible with the MZ 80K. The MZ 700 serie is made up of four machines : the first three ones were launched in 1983 and the last one was launched late in 1985 (in fact, this one is the "ancestor" of the MZ 800) : the MZ 710 was the "naked" model, the MZ 720 had an integrated tape recorder and the MZ 730 had an integrated plotter too. The fourth model was the MZ 780 which had a 80 columns card, a floppy disk drive too and a Centronics port. It worked under CP/M. There was no language in ROM, the ROM had only 2 KB (just for boot and for OS calls), it had to be loaded from tape. So there was a lot of language on this machine (more than 5 basics, assemblers, pascal, lisp, C, fortran, Comal, forth). The games were a bit poor because of the low rez, but there were 512 graphic characters in ROM which can be used to offset it. It will be replaced with the MZ 800 serie.

MZ800 & 1500 Series

The sharp MZ 800 is the successor of the MZ 780. It was partially compatible with the 700 serie and by the way, with the old MZ 80K serie too. The MZ 800 had an integrated tape recorder like the 700 which works at 1200 bauds. It can be substituted for a Quick disk unit, which is a small 2'8 inches disk with a sequential access. Like the MZ 700, there is no language in ROM, it has to be loaded from tape, quick disk or floppy disk. The ROM contains only boot code and OS calls and special code to allow the user to use the 64 Ko ram as a virtual disk. A single or double 5'25 inches disk drive can be connected on the 800, then it becomes a CP/M compatible. It works then under a special version of CP/M called P-CP/M, some great products like Wordstar, dBase II, Multiplan were adapted on it, it is possible (under CP/M) to read multiple disk formats from the 360 Ko (sharp format) to the 720 Ko (CP/M IBM PC format). A little color plotter (compatible with the one which was integrated on the MZ 730 or MZ 780) can be connected too. It was sold in Japan under the name "SHARP MZ 1500", the MZ 1500 is the same characteristics except its black case.
