Important Hard disk drives and removable storage devices may require special software for the computer to recognize the device. Check the documentation that came with your device or contact the device’s manufacturer for more information.

Additional Wide Ultra2 SCSI Drives

Your computer comes with two internal Wide Ultra2 SCSI drives. A PCI card and cable inside the computer make it possible to connect an additional internal drive and external Wide Ultra2 SCSI devices. You can connect up to three internal SCSI drives or connect additional SCSI devices to the port the card provides on the rear of the computer.

Additional internal Wide Ultra2 SCSI devices connect to the data cable supporting the drive that came with the computer. This cable has a built-in terminator so you don’t need to add one.

You must assign a SCSI ID number to every additional device and the number must not conflict with the ID number already assigned to a drive on the SCSI chain. Your Macintosh comes with two drives with ID 0 and 1. A third factory-installed drive has ID 2. The SCSI PCI card has ID 7.

Other Types of SCSI Drives

The SCSI card inside your Macintosh supports other types of Wide Ultra SCSI drives, as well as Wide Ultra2 SCSI devices. However, if you mix the different kinds, your system will operate at the speed of the slowest device. If you want optimal performance using the card, use only Wide Ultra2 SCSI devices. To maintain optimal performance using another kind of SCSI device, add a PCI card that supports the device.

Instructions for drive installation appear in the section “Installing a Hard Disk or Other Internal Storage Device” on page 42.

Note: For information about the length of the cable to connect SCSI devices, see the section “Cable Length Limits,” in the Technical Information booklet that came with your computer.

About PCI Expansion Cards

Your Macintosh can accommodate additional printed circuit boards (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. Note: Mac OS X Server does not support most add-on PCI cards or other devices requiring drivers that are not built into Mac OS X Server.

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 Appleā€™s presence in the computing market but also laid the foundation for the modern computing experience that would follow in the ensuing years.
