PTS-DOS is a disk operating system, a DOS clone, developed in Russia by Phystechsoft. A few programmers quit Phystechsoft and founded Paragon GmbH.

Thus there are two versions (derivatives) of PTS DOS: Paragon DOS Pro 2000 and PTS-DOS 2000.

PhysTechSoft continued developing PTS DOS and finally they released PTS DOS 32.
