Documentation and support tools
The description in the object is the result of the use of:
- A Real Programma 101 of Museum Tecnologic@mente.
- Original Function diagrams of the Programma 101.
- Data base.
- CAD simulator on PC.
All documentation, including logic diagrams of the machine translated and simulated and the supporting material, is in electronic format and are available at the Museo – Laboratorio Tecnologic@mente of Ivrea.
The understanding of this document is facilitated by the knowledge and use of all of the documentation and the simulator.
