disk operating system , aDOS clone, developed inRussia byPhysTechSoft .History and versions
PhysTechSoft was formed in 1991 in
Moscow ,Russia by graduates and members of MIPT, informally known as PhysTech. In the end of 1993, PhysTechSoft released first commercially available PTS-DOS as PTS-DOS v6.4 [http://www.phystechsoft.com/index.php?page=2 Official PhysTechSoft site: About PhysTechSoft] ] (version numbering obviously seems to follow versions of MS-DOS, as Microsoft released MS-DOS 6.2 in November 1993).Some programmers who left PhysTechSoft in 1995 founded
Paragon Software GmbH , took source code with them and released their own version named PTS-DOS v6.51CD. According to official PhysTechSoft announcements, these programmers violate both copyright laws and Russian military laws [http://www.almnet.de/ptsdos/ptsfaq.html#secII Unofficial PTS-DOS FAQ in English] ] , as PTS-DOS was developed in close relationship with Russian military and thus may be subject tomilitary secret .PhysTechSoft continued development on their own and released PTS-DOS v6.6 somewhere in between and presented PTS-DOS v6.65 at
CeBIT exhibition in 1997. Next version from PhysTechSoft, formally PTS/DOS Extended Version 6.70 [http://www.almnet.de/ptsdos/ptsfaqd.html#absIV Unofficial PTS-DOS FAQ in German] ] was labelled PTS-DOS 2000 and is still being distributed as a last 16-bit PTS-DOS system,as of 2007 .Paragon continued PTS-DOS line and released Paragon DOS Pro 2000 (also known and labelled in some places as PTS/DOS Pro 2000). According to Paragon, this was the last version and all development since then ceased. Moreover, this release contained bundled source code of older PTS-DOS v6.51.
Later, PhysTechSoft continued developing PTS DOS and finally they released PTS-DOS 32 (formally known as PTS-DOS v7.0), which added support for the FAT-32
file system .PTS-DOS is certified by
Russian Ministry of Defence [http://www.phystechsoft.com/ptsdos/index.html Official PhysTechSoft site: Operating System PTS-DOS 2000] ] .Hardware requirements
