The picture below presents the only connector available on the Matra RC1173A


After some studies, it seems that device is a "pupitre" from MATRA that sould be connected to a PABX Matracom (45xx series) of CGCT type.The device seems to be using a micro-controler Philips/RTC 84C21 and 84C85 using probably the firmware HX00070xx et HX00072xx
