Task: Purchase a Long T15 Torx Screwdriver for Removing Case Screws on a Classic Macintosh Computer
Needed: Web browser, Classic Macintosh
Time: 5-10 minutes
Introduction
Getting inside the case of a classic Macintosh can be necessary for assessing and repairing circuit board damage from leaky capacitors, removing and/or replacing batteries that could leak, and performing upgrades such as adding more RAM. Unfortunately, Apple made it difficult to get into the case to prevent injury or death due to the high voltages (1000+V) that remain in the CRT due to capacitance after powering down. The analog power board can also deliver dangerous shocks.
Apple made it difficult to remove the case in two ways. First, the screws they used are of the Torx variety featuring a star shaped pattern. These require a special screwdriver with a head that is Torx compatible and of the right size. The classic Macs require the T15 size of Torx. Second, Apple embedded two of the screws deep under the top handle making it inaccessible with standard screwdrivers. A longer T15 Torx is required.
Instructions
Purchase a long T15 Torx screwdriver for opening up the case of a classic or compact Macintosh (e.g. Mac Plus, Mac SE, Mac Classic). There are several varieties available on Amazon and eBay, for example. Expect to pay around $10 for a single unit or $20 for a set. I purchased this one for $10 (see photo below). I also have a Pittsburgh 34-piece precision screwdriver set that includes a flexible extension that makes it long enough attached to the main shaft to open a case. This is a nice option because it has the flex and other attachments that can be used for other purposes.
Comments
A must-have for classic Mac work.
