Clearly, most of us cannot buy a new computer each time a new advance in microprocessor technology occurs. Recognizing this, The PC Upgrader's Manual explains how to prolong the life of your original IBM PC series or compatible series, and provides techniques to expand their levels of performance. This revision will also provide information on upgrades to the recent PS/2 series, as well as information on executing software for the PS/2 on earlier members of the IBM PC family. In addition to this coverage, this edition features new information on upgrades of modems and printers--the most common peripheral devices that can be used with both PCs and PS/2s. It also includes valuable advice to users on isolating and resolving problems that could occur.
