Musculoskeletal discomfort

As with any activity that involves sitting for long periods of time, using a computer can make your muscles sore and stiff. To minimize these effects, set up your work environment carefully, using the guidelines that follow, and take frequent breaks to rest tired muscles. To make working with your computer more comfortable, allow enough space in your work area so that you can change position frequently and maintain a relaxed posture.

Another type of musculoskeletal concern is repetitive stress injuries (RSIs), also known as cumulative trauma disorders (CTDs). These problems can occur when a certain muscle or tendon is repeatedly overused and forced into an unnatural position. The exact causes of RSIs are not totally understood, but in addition to awkward posture, such factors as the amount of repetition, the force used in the activity, the individual’s physiology, workplace stress level, and lifestyle may affect the likelihood of experiencing an RSI.

RSIs did not suddenly arise when computers were invented; tennis elbow and writer’s cramp, for example, are two RSIs that have been with us for a long time. Although less common than other RSIs, one serious RSI discussed more often today is a wrist problem called carpal tunnel syndrome, which may be aggravated by improper use of computer keyboards. This nerve disorder results from excessive pressure on the median nerve as it passes through the wrist to the hand.

This section offers advice on setting up your work area to enhance your comfort while you use your computer. Since the effects of repetitive movements associated with using a computer can be compounded by those of other work and leisure activities to produce or aggravate physical problems, proper use of your computer system must be considered as just one element of a healthy lifestyle.

No one, of course, can guarantee that you won’t have problems even when you follow the most expert advice on using computer equipment. You should always check with a qualified health specialist if muscle, joint, or eye problems occur.

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.
