RS-POS is a computer operating system developed by Royalsoft. The system can be found running on the Mikropekka computer.

The operating system is a DOS-like providing a command-line interface (CLI) for user input and control of the system. Basic commands are used to run programs, read and execute disks, exit applications, etc. The system is integrated with physical buttons such as the power and reset buttons found on the case of the TURBO X33.

It is likely based on MS-DOS or PC-DOS.
