This review is from: Macintosh Repair Secrets (Paperback)
Larry Pina's handbooks are the leading resource for anyone trying to repair or upgrade old Apple Macintosh computers from the mid 80's to the early 90's. They serve to demystify the workings inside the box. There are people around the world that will repair your faulty Mac for a fee, just as they did years ago. It's a skilled job and the fees reflect this. This book will pay for itself the first time you use it. Most of the spare parts are sold for a few pennies. Modern equivalents are better than the original parts and will extend the life of your Mac Classic.
This volume deals with the following models: Macintosh 128k, 512k, 512kE, Plus, XL, Lisa and SE (twin floppy).
For the majority of users, the problems start with ageing components on the power supply board, specifically capacitors, voltage controllers and rectifiers.
Pina begins with a list of "do's and don't's" regarding safety when working with electrical equipment and then lists the tools that you will need to effect repairs.
Topics include Take Apart, Testing, Fault Finding, Upgrading, Repair and Calibration. He also lists expected voltages at test points.
He also includes compatible parts and a list of vendors for those parts.
The volume also includes clear diagrams throughout so you cannot get lost in the maze of components.
The original book also included a floppy disk with a suite of Test Pattern programs for the different models. My second hand copy did not include this disk but it is possible to find the disk image by searching on-line.
Along with 'The Dead Mac Scrolls' and 'Mac Classic & SE: Repair & Upgrade Secrets', 'Macintosh Repair and Upgrade Secrets' is an essential tool to keep in your library.
There are many on-line resources and videos regarding old Macs but there is something very rewarding in reading the instructions and taking the steps yourself instead of following someone on screen.
Even reading them as an information source is rewarding when you consider how simple things were back then and that computers are not nearly as complicated and secretive as you might have imagined.
