PTS-DOS 2000 – a powerful and fast 16-bit disk operating system that is fully compatible with MS-DOS and all its applications. In addition to DOS itself, the PTS-DOS package includes: a peer-to-peer LotLAN local area network that supports all standard network functions, a file manager, an archiver, a boot manager, boot virus protection tools, a graphical web browser, an e-mail client, ftp- client, telnet, as well as a large set of various system utilities. PTS-DOS 2000 gives you more conventional memory than any other DOS.
PTSDOS has originally been developed at PhysTechSoft, Moscow, an enterprise which is sponsered by the Russion Defense Ministry. They finally gained allowance to distribute their DOS commercially, which lead to the releases of PTSDOS V6.4 and V6.5 in Germany.
In 1995, some programmers (according to their statements dissatisfied with the vast bureaucracy at PhysTechSoft) left PhysTechSoft and took copies of the whole source code of PTSDOS with them. They founded “Paragon” and released an own version of their DOS, PT$DOS 6.51CD. This version fixed a lot of urgent bugs in PTSDOS 6.5 In the meantime, PhysTechSoft released PTSDOS 6.6, which also fixed a lot of bugs in V6.5.
According to the president of PhysTechSoft, Paragon has no permission to sell anything abroad and is therefore not only violating copyright laws, but also Russian military law. We are going to see a major lawsuit in this case.
