For other uses, see MC-DOS.
MC-DOS (short for Minicomp Disk Operating System, later changed to just DOS after version 10/X) is a text-based disk operating system for x86-based personal computers developed by Minicomp. It is the Project Fossil counterpart of MS-DOS, a disk operating system developed by Microsoft.
== History ==
PC-DOS's development started in May 579, initially planned as an extension to the pre-existing Minicomp Simple line of operating systems, due to some files in the final version listing it as "AdvSimple", short for Advanced SIMPLE. Its first version released on March 11th, 580. PC-DOS was also ported to MCIP system by releasing DOS/MCI 1.0 on the same day as PC-DOS 1.0 released, which was developed in collaboration with Morsell Laboratories. DOS Shell was introduced on PC-DOS 2.0, and the system was later renamed to MC-DOS in 586. Due to dwindling sales, the last version was released in 606 with a service release releasing the following year. After several years, Minicomp released the source code for all versions in 634. Various versions of DOS were also released in Japan under the name of DOS-NH (later changed to DOS/AS to target other Asian countries), though the changes found in DOS/AS were later integrated into the mainline versions of MC-DOS 6.
