The origin of the device
The T65 was the standard telephone in the Netherlands from 1965 to 1988. Many Dutch households got their first telephone connection during this period. The T65 is therefore a well-known appearance. The device was developed by Dutch PTT (Post, Telefonie en Telegrafie) in collaboration with the German company Krone. The technical part, which had to meet Dutch PTT requirements (standard ’51), was designed by the professor H. Mol from Rotterdam. At the bottom of the device are stated: “PTT type T65”, the name of the manufacturer and the production date. Initially, the T65 was supplied with or without earth key. Later, from the beginning of the seventies only with earth key. The standard color of the T65 was gray, with gray cords and some cream colored parts. Years later, the devices were also available in black, green, orange, blue, red, white, and brown. Various artists have developed a special hood. And because people became more and more curious about the interior of the device, devices with a transparent cover have also been launched on the market. The T65 has only been available as a rental unit; for Fl. 2.50 (€ 1,13) per month.
The weight of the T65 was reduced by half compared to older models. The device had a cavity at the rear that served as a handle. making the device easy to move. It was possible to use two T65 units in a twin circuit. When there was an incoming call, both phones rang at the same time, but if one of the two phones was answered, the other was excluded. This made eavesdropping or speaking through the other device impossible.
