It sure is great to get out of that bag!''} \end{center} \paragraph{% On January the 24th of 1984, Macintosh introduced itself to the world. In comparison % to the dolled-up computers we take for granted today, personal computers of the late % 1970s and early 1980s were ... rather impersonal. Personal meant that a person might % own one, not that a person may be comfortable using one. Macintosh represented a fundamental % shift in how people interacted with machines. \\ \textit{Instead of teaching humans about computers,} the theory went, % \textit{we should teach computers about humans.} A laudable goal indeed, at a % time when most peoples' knowledge of computers was either arcade-style gaming or % the necessity of memorising an arcane set of textual commands for getting work done. % } \begin{center} \textit{``Unaccustomed as I am to public speaking, I'd like to share with you\\ a % maxim I thought of the first time I met an IBM mainframe: \\Never trust a computer % that you can't lift!''} \end{center} \paragraph{% Macintosh was a computer for the masses. Every aspect of it was engineered to be % appealing to the everyday user. Macintosh looked radically different from other % personal computers of the time, many of which were shaped like suitcases or overly % thick keyboards. Macintosh's price, too, was designed to be appealing - in comparison % to the Lisa, with which it shared the 68000 at its heart and the idea of an entirely % graphical interface, Macintosh was the very epitome of value, at \$2,495 (the Lisa cost % \$9,995 at its inception, and at the time of Macintosh's introduction was still \$3,495 % for a base model, a full thousand dollars more expensive than Macintosh.) % } \paragraph{% Many books have been written about the historical context of Macintosh, and the line % that dutifully followed it; hence, there is no need to go into greater detail here. % This book exists to fulfill a need, and to fill a niche. There is a thriving community % of people from many walks of life, from well-to-do collectors to impoverished students, % united by a love of Macs. Unfortunately, many of the older Macs they so dearly love are % rather past their prime; so much so that modular repairs are sometimes no longer sufficient % to keep machines running. Component-level repair is becoming an unpleasant fact of life for % those who would keep their Macintoshes in workable condition; among the prime culprits are % aged capacitors and blown resistor networks. % } \paragraph{% Of course, in repairing Macintoshes it helps to know something about them - how they should % behave when working to specifications, and it especially helps to know what their limits and % quirks are. For instance, while it is physically possible to install 32MB of RAM in a Colour % Classic, no more than 10MB would be seen, and thus it would be a waste of (now fairly expensive) % RAM SIMMs. % } \paragraph{% This need is met, for users of Mac OS X and iOS, by a piece of software called Mactracker. It is also % available for Windows, but has not been updated on that platform for some years. Formerly, it was % available for Mac OS 8.6; this version has been withdrawn. A Linux port has been enquired about, % and as of the time of writing, it has not materialised and is unlikely to. % Ian Page has done a great good in making Mactracker available to the community at no % charge, and it is a supremely useful resource which I recommend highly to anyone who works on Macs % for their livelihood, or in their leisure. I would be lying to say that it has not been % incredibly useful for researching the bulk of specifications in this tome. Thankfully % I can get away with using the Windows version, outdated though it be, due to only covering % Old World Macs. % } \paragraph{% This book, however, seeks not only to provide the practical specifications of known Macintoshes, % but also to collect, in one place, known repair techniques and background technical information. % }
