DRAM Configurations

Your computer’s DRAM can be expanded to a maximum of 1024 MB by adding DIMMs to the four DRAM DIMM slots on the main logic board.

DIMMs must fit these specifications:

m“PC-100” Synchronous DRAM (SDRAM)

m3.3 volts ( V )

m64-bit wide, 168-pin module

mMaximum number of memory devices on DIMM is 16.

mUnbuffered; do not use registered or buffered Synchronous DRAM (SDRAM).

mNot more than 2.0 inches high

Important This computer uses SDRAM DIMMs. DIMMs from older Macintosh computers are not compatible with your computer and should not be used even though they fit into the DRAM DIMM slots.

Note: Different size DRAM DIMMs can be installed in any order in any DIMM slot. Unlike older Macintosh computers, DIMMs need not be installed in pairs.

To increase DRAM to the maximum of 1024 MB, fill all four slots with 256 MB DIMMs. Any 256 MB DIMMs you install must use 128 megabit (Mbit) device technology. Your computer requires at least one DIMM to operate.

For instructions on installing DRAM, see the section “Installing DRAM” on page 40.

About Internal Storage Options

Your Macintosh has four internal drives. Two hard disks occupy two positions on the lower drive carrier, and a CD-ROM drive fills the upper bay. The lower drive carrier can accommodate one additional hard disk drive.

For technical information about the power requirements for devices the computer can accommodate, see the Technical Information booklet that came with the computer.

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.
