5. Beginning of production: 1988.
6. Termination of production: still in production.
7. Total output of machines: over 200.
8. Description: 40U6 model continues the line of mobile control multiprocessor machines originated in 5E26 computer. It has modular design and high viability achieved by duplication of some modules and redundancy. Powerful hardware control system allows restoring the control processes after equipment malfunctions or failures. The computer functions in arduous real-time mode, is intended for work over a wide spectrum of environmental and mechanical actions and furnished with sophisticated software for automated programming.
