Opening the keyboard on an Alcatel Telic Minitel 1

Matériel

Hello,

I have recently purchased an Alcatel Telic « Terminatel 254 » - I believe it is an export version of the Minitel 1. There are some hardware differences but the construction is mostly the same.

I would like to open the keyboard to repair the cable. Does anyone have any advice? There are 3 clips but I cannot open it.

… I must take a M1 and see how it behaves. I don’t promise you a very quick answer from my side.

Question (en Français) : Quelqu’un a-t-il déjà totalement démonté le clavier d’un M1 Telic (et pas M1b) pour indiquer à notre ami comment procéder ?
