A “sad Macintosh” icon appears and the computer won’t start up.

This icon indicates that your Macintosh cannot start up because of a problem with the system software or the computer hardware.

Eject any floppy disks by turning off the computer and then holding down the mouse button while you turn the computer on again. Try starting up with the Macintosh Performa CD : Performa Software. For instructions on how to start up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section “Repairing a Damaged Disk” later in this chapter. If the “sad Macintosh” icon appears again, consult the service and support information that came with your computer for information on contacting an Apple-authorized service provider or Apple for assistance.

The hard disk icon does not appear on the desktop.

If you don’t see a hard disk icon on the desktop, try the following:

mUse the Drive Setup program to make the disk available. Drive Setup is on the Macintosh Performa CD: Performa Software that came with your

computer. (For instructions, start Drive Setup, then choose Drive Setup Guide from the Guide [h] menu or see “Checking for Damage On Your Hard Disk” in the section “Repairing a Damaged Disk” later in this chapter.)

mIf the hard disk is internal, shut down your computer, wait at least 10 seconds, and then turn it on again.

mIf the hard disk is external, make sure that it is turned on and that its cable is connected firmly; then restart the Macintosh.

mCheck the ID numbers of all SCSI equipment connected to your computer. Each SCSI device must have its own unique ID number. If your computer came with the optional CD-ROM drive installed, the drive has SCSI ID number 3. The computer itself (the main logic board) has SCSI ID number 7. For information on setting SCSI ID numbers, see the manuals that came with your SCSI equipment and Chapter 3 of this manual.

5400 Series specifications

The Apple 5400 series, released in the mid-1990s, was a significant milestone in Apple's line of Macintosh computers. Characterized by its all-in-one design, this series was particularly popular for its blend of style, functionality, and performance. The 5400 series aimed to provide users with an accessible and seamless computing experience, making it appealing to both home users and education markets.

One of the standout features of the Apple 5400 series was its aesthetically pleasing design. The compact form factor housed all essential components, including the monitor, CPU, and storage, allowing for a cleaner workspace. Its unique design included a swivel base that enabled users to adjust the monitor's angle easily. The 5400 series boasted a 15-inch display with a resolution of 640x480 pixels, providing clear and vibrant visuals suitable for both productivity and entertainment.

Under the hood, the 5400 series was powered by the PowerPC 603e processor, which operated at speeds varying between 180 MHz and 240 MHz. This processing power was complemented by a bus architecture that supported speeds of 60 MHz, enhancing the overall responsiveness of the system. With options for 16 MB or 32 MB of RAM, expandable to 128 MB, the 5400 series offered enough memory for multitasking and running resource-intensive applications, a key requirement during that technological era.

The Apple 5400 series featured a range of innovative technologies that set it apart from competitors. It came equipped with an ADB port for connecting keyboards and mice, as well as several expansion slots for peripherals. Notably, the inclusion of an integrated CD-ROM drive made it one of the first in its class, allowing users to access software and multimedia content easily. Additionally, it supported Apple’s QuickTime technology, enabling users to experience multimedia applications with video and sound.

Another notable characteristic of the 5400 series was its commitment to connectivity. It shipped with a built-in modem and included Ethernet capabilities, making it easier to connect to networks, surf the emerging internet, and share files. This level of connectivity was essential as the online landscape began expanding in the mid-90s.

In summary, the Apple 5400 series represented a well-rounded approach to personal computing in its time. With its stylish design, robust features, and commitment to both performance and connectivity, it carved out a dedicated user base. Though ultimately phased out with the evolution of technology, the legacy of the 5400 series continues to influence modern computing design and functionality.
