You may have to raise your chair so your forearms and hands are at the proper angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you can use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you may lower the desktop to eliminate the need for a footrest. Another option is to use a desk with a keyboard tray that’s lower than the regular work surface.

mPosition the mouse at the same height as your keyboard. Allow adequate space to use the mouse comfortably.

mArrange the monitor so the top of the screen is slightly below your eye level when you’re sitting at the keyboard. The best distance from your eyes to the screen is up to you, although most people seem to prefer 18 to 28 inches (45 to 70 cm).

mPosition the monitor to minimize glare and reflections on the screen from overhead lights and windows. You may want to use a tiltable monitor stand. The stand lets you set the monitor at the best angle for viewing, helping to reduce or eliminate glare from lighting sources you can’t move.

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.
