If your computer’s performance decreases

If you notice a decrease in your computer’s speed and general performance after you add special software (a control panel, system extension, or custom utility), it may be because the software does not work well with Macintosh computers built with the PowerPC microprocessor.

mTo find out if the new software is the problem, hold down the Shift key while you restart the computer. This temporarily turns off control panels and extensions. If the computer performs better without this software, one of these items is likely to be the problem.

mUse the Extensions Manager control panel to turn off a system extension or set of extensions. For detailed instructions, see the “Setting Options” topic of Macintosh Guide, available in the Guide (h) menu. If the computer performs better when an extension is turned off, contact the extension’s manufacturer for information or an upgrade.

mUse the Memory control panel to turn off virtual memory. For more information on virtual memory, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu.

mIf you use several application programs at the same time, your computer’s performance will increase if you install more RAM (random-access memory). See “Expanding Memory” in Chapter 3.

If you still do not notice an improvement, you may want to reinstall system software on your startup hard disk. See the Macintosh Performa CD booklet for instructions.

6200CD Series, 6300CD Series specifications

The Apple 6300CD and 6200CD Series were notable additions to Apple's line of portable computers in the mid-1990s, blending compact design with functional capabilities that appealed to both personal and professional users. These series were part of Apple's PowerBook lineup, embodying the transition to more powerful and versatile portable computing.

The Apple 6300CD was recognized for its striking design that combined portability with performance. It featured a high-resolution grayscale display, offering a clear and vibrant viewing experience, which was essential for graphic design and multimedia tasks. One of the standout features was its integrated CD-ROM drive, allowing users to easily access software, music, and multimedia content, thus enhancing productivity and entertainment options.

The core of the 6300CD was the PowerPC 603 processor, clocked at 100 MHz, which provided a significant performance boost over its predecessors. Coupled with a generous amount of RAM, it handled multitasking and demanding applications with relative ease. The 6300CD also offered several connectivity options, including Ethernet, SCSI, and ADB, which made it adaptable to various networking and peripheral configurations.

On the other hand, the Apple 6200CD Series brought a balance of performance and affordability. This model also featured a PowerPC 603 processor but at a slightly lower clock speed, making it a cost-effective choice for users who did not require the highest specifications. The 6200CD was designed with a more basic but still effective color display, targeting users who needed reliable performance for everyday tasks, such as word processing, browsing, and basic graphic work.

Both series were equipped with a robust suite of software, including the classic Mac OS, enabling users to utilize a wide array of applications. The inclusion of a trackball, along with a full keyboard, contributed to user-friendly navigation and productivity, making these laptops appealing for a broad audience.

In summary, the Apple 6300CD and 6200CD Series exemplified the innovation and design ethos of Apple during the era. With their combination of solid performance, portability, and user-friendly features, these PowerBooks were well-received in the 1990s and remain a nostalgic reminder of Apple's commitment to creating powerful, efficient, and aesthetically pleasing computing solutions.
