But as well as cleaning the keys, which can only be done in depth by completely dismantling the keyboard, we're also going to look at how to repair one of the most common ST problems: soldering of the joystick sockets. This is most often characterised by either the mouse no longer working or not working properly (the cursor won't go up, for example), or the joysticks not responding properly (loss of direction, or firing buttons, etc.). It's easy to fix these problems, but unfortunately you have to dismantle the keyboard to do so.<\/p>\n<blockquote><p><strong>Caution: Be very careful not to lose the rubber domes on the keys or the small screws on the keyboard!<\/strong><\/p><\/blockquote>\n<p>Hold the keyboard in front of you and remove all the visible screws, including those under the adhesive.

Pour \u00eatre plus pr\u00e9cis, vous ne trouverez pas dans ces articles comment r\u00e9parer une alimentation hors service, changer des composants sp\u00e9cifiques sauf s&#8217;ils sont facilement rempla\u00e7ables, ni de m\u00e9thodes sur comment souder proprement les composants \u00e9lectroniques par exemple. Il existe cependant sur internet et notamment sur Youtube bon nombre de tutoriels vid\u00e9o qui vous donneront des pistes. Si vous avez le moindre doute, un seul r\u00e9flexe \u00e0 avoir, venez en discuter sur notre Discord ! Le premier article sera donc d\u00e9di\u00e9 aux Atari STf ou STe, une gamme de machines ch\u00e8re \u00e0 notre c\u0153ur et avec laquelle bon nombre de nos membres ont eu leurs premiers \u00e9mois informatiques. Plus de trente ans apr\u00e8s la sortie de la machine, celle-ci a besoin de premiers soins, que nous allons r\u00e9aliser ensemble.

L&#8217;Atari 1040STf de Jean-Fran\u00e7ois Freitas avant d\u00e9montage &nbsp; D\u00e9monter proprement son Atari ST : Tout d&#8217;abord, munissez vous de tournevis cruciformes et d&#8217;une petite pince plate. Retournez votre ST sur la face avant (posez le sur un chiffon par exemple pour ne pas le rayer) et d\u00e9vissez toutes les vis ici entour\u00e9es en bleu et vert. Par contre, ne les m\u00e9langez pas : les vis entour\u00e9es de vert sont celles de la carrosserie en plastique, les vis entour\u00e9es de bleu sont celles qui tiennent le lecteur de disquette interne en place. Si cela peut vous aider, utilisez des r\u00e9cipients diff\u00e9rents pour chaque cat\u00e9gorie de vis (carrosserie, blindage m\u00e9tallique interne, lecteur de disquettes). Les vis \u00e0 retirer sous la carrosserie. &nbsp; Une fois les vis enlev\u00e9es, vous pouvez retourner votre Atari ST et le remettre face avant sur le dessus, et d\u00e9licatement, retirez toute la carrosserie sup\u00e9rieure en la soulevant verticalement. Elle devrait pouvoir s&#8217;enlever sans trop de difficult\u00e9s.
