One of the challenges we are facing in our project is connecting antique display devices to the brand new travel information system we are building. If you have traveled by train in the Netherlands you are familiar with them: large displays with booklets for destinations and departure times. It contains a number of booklets which are controlled by a stepper engine. The devices are called CTA’s, were developed in the eighties and are a solid piece of engineering. Behind the track indicator, which doubles as a door, is a temperature control for the heating, a power socket for connecting electrical equipment, a telephone socket and a connector for testing. Oh yes, did I mention it is heavy?
