Arranging Your Office

Here are some guidelines for adjusting the furniture in your office to accommodate your physical size and shape.

mAn adjustable chair that provides firm, comfortable support is best. Adjust the height of the chair so your thighs are horizontal and your feet flat on the floor.

The back of the chair should support your lower back (lumbar region). Follow the manufacturer’s instructions for adjusting the backrest to fit your body properly.

mWhen you use the computer keyboard, your shoulders should be relaxed. Your upper arm and forearm should form an approximate right angle, with your wrist and hand in roughly a straight line.

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 computer to minimize glare and reflections on the screen from overhead lights and windows.

45–70 cm (18–28 in.)

Top of the screen at or slightly below eye level (You may need to adjust the height of your monitor by placing something under it or by raising your work surface.)

Screen positioned to avoid reflected glare

Clearance under work surface

Feet flat on the floor

G3 Minitower specifications

The Apple G3 Minitower, released in 1997, marked a significant evolution in Apple’s desktop computer lineup. As part of the G3 series, it was geared towards both professional users and creative enthusiasts, showcasing powerful performance in a compact form factor. This machine was notable for its distinctive design, featuring a sleek, gray plastic enclosure that was both stylish and practical.

At the heart of the G3 Minitower was the innovative G3 processor, which featured a 250 MHz initial speed, and eventually models offered up to 500 MHz. The G3 architecture utilized a combination of RISC (Reduced Instruction Set Computing) technology and sophisticated software optimizations, allowing for increased performance, especially when handling multimedia applications. The system's performance was complemented by the inclusion of the latest technologies at the time, such as PCI expansion slots, enabling users to add graphics cards and other peripherals to enhance functionality.

The standard configuration came with 32 MB of RAM, which was expandable to a maximum of 1 GB. This capacity made it suitable for demanding tasks such as graphic design and video editing, common uses for the target market. Storage options were generous as well, with the G3 Minitower typically coming with a 4 GB hard drive, upgradeable to larger capacities. This component played a vital role in the machine's ability to efficiently store and manage large files associated with multimedia projects.

In terms of connectivity, the G3 Minitower included USB ports, which were becoming increasingly popular in the late 1990s, as well as a built-in modem and Ethernet port for internet connectivity. The Minitower also supported Apple's innovative FireWire technology, allowing for faster data transfer rates, which was especially advantageous for connecting external devices like digital cameras and external hard drives.

The G3 Minitower ran on the Mac OS 8 operating system, giving users access to a user-friendly, robust interface that was ideal for both new and experienced users. With support for a wide range of software applications, it appealed to educators, designers, and developers alike.

Overall, the Apple G3 Minitower represented a significant leap in desktop computing for Apple and firmly established the G3 architecture as a cornerstone of their product offerings for years to come. Its powerful performance, expandability, and design made it a beloved choice among Mac enthusiasts of the era, embodying the spirit of innovation that Apple was known for.
