Installing PCI Cards, Memory,

and Internal Storage Devices

This chapter provides information about peripheral component interconnect (PCI) expansion cards, memory, and internal storage devices, and explains how to install them.

Installing these items involves three procedures (detailed steps for each are provided later in this chapter):

mopening the computer

minserting the card, memory module, or storage device into a specific slot or expansion bay

mclosing the computer

Warning Apple Computer recommends that you have an Apple-certified technician install memory, PCI expansion cards, and internal storage devices. Consult the service and support information that came with your computer for instructions on how to contact an Apple-authorized service provider or Apple for service. If you install these items yourself, you risk damaging your equipment, and this damage is not covered by the limited warranty on your computer. See an Apple-authorized dealer or service provider for additional information about this or any other warranty question.

About PCI Expansion Cards

You can install printed circuit boards (called “cards”) for video and graphics applications, networking and communications, additional processing power, or other purposes. The cards fit into connectors, called “expansion slots,” inside the computer.

Your Macintosh has three expansion slots, each designed to accept a 7-inch or 12-inch long PCI card. Install only expansion cards that come with Macintosh drivers and are compliant with the PCI 2.1 standard. NuBuscards cannot be used in these expansion slots.

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.
