When the first microprocessor controllers were put into service in Paris from 1978, three models were present: the TAG (Garbarini-Omera), the VPZ (SFIM), and the Thomson-CSF controller.
For each of these controllers, a programming case was required. In order to facilitate their maintenance, a universal case enabling intervention on the three controller models was developed and patented by EDF in 1985.
This is an EPSON base, modified with an EPROM support.

Controller developed in 1955 by the municipal lighting laboratory of the city of Paris. It offered 3 to 6 phases and 2 time programs obtained by 2 motors.
It was designed when no controller at that time offered a modular design allowing for expansion.

Some municipal organizations have developed self-made intersection automatons to respond either to a lack of a product satisfying their needs on the market, or for reasons of economy.
These controllers disappeared with the arrival of regulation and the standards imposed on intersection controllers.
