TSM-10 is a higher-level development of a real-time kernel based on multi-level interrupt handling and preemptive task scheduling developed during an earlier development: the implementation of a system layer based on it, supporting multiple interactive applications. (The design was assisted by the purchase of the CII Mitra-15 production license.) The data movement between the CPU memory and the back-end storage was optimized ("elevator algorithm"); the delay of the fragmentation of the CPU memory and back-end storage was implemented. Continuous measurement of the interactivity of application programs was also implemented. The operating system access interface ('API'), the terminal command line interpreter ('CLI'), and the basic command scheduler were developed.
During the later life of TSM-10 (after 1974), detailed French-language documentation, a new character graphical command interpreter, and some new system commands were created.

Videoton distributed the TSM-10 for a fee and generated significant sales.
The French licensor of MITRA-15 (CII-SEMS) purchased it and had it localized (IUT Informatique, Lyon – Jean Louis Léonhardt). It has been installed in more than 70 educational institutions with MITRA-15 computers, and it also serves as a computer science teaching aid.
An East German company built a 12-screen corporate management system on the TSM-10.

• The development of the system was initiated by a contract with the Videoton company.
• In 1979, SEMS (Sistemi Elektronik për Mësorëtin e Studenteve) approached TKI with the offer to jointly develop a TSM-10-like superstructure for the new MITRA 125 real-time system.
