Your Macintosh has four expansion slots, each of which has a PCI card up to 12 inches long. Install only expansion cards that come with Macintosh driver software and that comply with the PCI 2.1 standard. NuBus™ cards cannot be used in these expansion slots.

The one unoccupied PCI slot can accommodate a mixed voltage (5.0 V or 3.3 V ) card with a 33 MHz frequency and 32-bit or 64-bit data widths. This slot will not accommodate a 66 MHz card. (The slot labeled number 1 accommodates a 3.3 V graphics card with 66 MHz and 32-bit data width. This card is already installed in your computer.)

Expansion Card Power Requirements

The combined power consumption of expansion cards must not exceed the limits specified for your Macintosh model. For details, see the Technical Information booklet that came with your computer.

mYour computer comes with three pre-installed PCI cards. You can add one more card that uses up to 25 W.

Warning To avoid damaging your computer and expansion card, do not attempt to install any expansion card without first checking the documentation for that card. If the documentation specifies that an Apple-certified technician must install the card (usually because the installation requires special training or tools), consult the service and support information that came with your computer for instructions on how to contact an Apple- authorized service provider for assistance. If you attempt to install the card yourself, any damage you may cause to the computer or card will not be covered by the limited warranty on your computer. If the card is not an Apple-labeled product, check with an Apple-authorized dealer or service provider to see if you can install it yourself.

For instructions on installing PCI cards, see the section “Installing a PCI Expansion Card” on page 52.

About the Server’s Battery

The Macintosh has a 3.6 V lithium backup battery installed on the main logic board. If you have intermittent problems starting up your server and the date randomly resets itself, you need to replace the battery. Replacement batteries for the Macintosh are available in many electronics and computer stores. You can install the new battery yourself or have an Apple- authorized dealer do it for you for a fee.

Replacing the battery may cause some settings on your computer, such as the date and network settings, to revert to factory default settings.

Important Make a note of the settings for communications programs before you replace the battery.

G3 specifications

The Apple G3, introduced in 1997, marked a significant leap in Apple's computer technology and design philosophy. This series of Macintosh computers was powered by the PowerPC G3 processor, which had a clock speed ranging from 233 MHz to 750 MHz, depending on the model. The G3 chip was notable for its advanced features, including a 32 KB L1 cache and the ability to support a more complex 256 KB L2 cache. This allowed the machines to execute instructions more efficiently than their predecessors, enhancing overall performance for various computing tasks.

One of the defining characteristics of the Apple G3 line was its innovative design, which combined form and function. The desktop models featured a sleek, curving case, famously known as the "Blue and White" G3, while the all-in-one iMac G3 showcased vibrant colors and an iconic translucent design that became a hallmark of Apple devices.

The Apple G3 was notable for its extensive use of USB ports, which was a relatively new technology at the time. This foresight helped pave the way for the adoption of USB peripherals, allowing users to connect a wide range of devices, from printers to scanners, with ease. Additionally, the G3 series also provided options for expansion via PCI slots, giving users the flexibility to upgrade their systems.

In terms of graphics, the G3 models were equipped with accelerators like the ATI Rage or the NVIDIA Riva TNT, providing improved visual performance for both professional applications and gaming. This was complemented by Apple's decision to support higher screen resolutions and better color depth, enhancing the multimedia experience.

Moreover, the Apple G3 introduced the Mac OS 8 operating system, which brought improved multitasking capabilities and a more streamlined user interface. This allowed users to experience a more intuitive and productive computing environment.

Overall, the Apple G3 line represented a critical evolution in Macintosh technology. It combined powerful processing, innovative design, and new technologies that set the stage for future developments in the Apple ecosystem. The G3 series not only solidified Apple’s presence in the computing market but also laid the foundation for the modern computing experience that would follow in the ensuing years.
