1.1.2 What is MiniOS7?
The MiniOS7 is an embedded O.S. designed for the 7521 series.
Developed by ICP DAS Co. Ltd; It is used to replace the ROMDOS used in
the 7188 series. Several brands of DOS have been created by various
companies. In all cases, DOS--whether PC-DOS, MS-DOS, or ROM-DOS--is a
set of commands or code which tells the computer how to process information.
DOS runs programs, manages files, controls information processing, directs
input and output, and performs many other related functions. The MiniOS7
provides the equivalent functions of ROMDOS while, in addition,
providing user specific functions for the 752N family.
