Your computer displays the message “This is not a Macintosh disk: Do you want to initialize it?” when you insert a CD-ROM disc in the CD-ROM drive.

mThe disc may use a format that the Macintosh cannot recognize.

Your computer ejects a CD-ROM disc without giving you any error message.

mMake sure the disc is flat in the tray and the disc label is facing up. If you’re using a small (8 cm) disc, make sure it’s centered within the tray’s inner ring.

mThe disc may need to be cleaned. (See “Handling CD-ROM Discs” in Appendix A.) If there are visible scratches on the shiny side of the disc, you may be able to remove them with a CD polishing kit (available from your audio CD dealer). If the scratches can’t be removed, you’ll need to replace the disc.

mThe disc may be damaged. Try another disc in the drive, and try the original disc in another drive. If the original drive reads other discs or if the original disc also doesn’t work in another drive, the disc is probably damaged. You’ll need to replace the disc.

You can’t open a document on a CD-ROM disc.

mTry opening the application program first; then open the document.

mRead the manual that came with your CD-ROM disc. Some discs come with software that you need to install on your computer before using the disc.

You can’t save changes you make to information on a CD-ROM disc.

mCD-ROM is a read-only medium. This means that information can be read (retrieved) from it, but not written (stored) on it. You can save the changed information on a hard disk or floppy disk.

Problems using ISO 9660 or High Sierra discs

You cannot access files on a CD-ROM disc that uses the ISO 9660 or High Sierra format.

mDiscs in the ISO 9660 and High Sierra disc formats have version numbers attached to file names. Some application programs need these version numbers in order to work with files. To make the version numbers available to programs on your computer, follow these instructions.

The Apple 5300CD, released in 1995, represents a unique chapter in Apple's history, catering specifically to the needs of mobile professionals and educational institutions. This portable Macintosh laptop was notable for its blend of performance, portability, and multimedia features, making it a versatile choice for various users.

At its core, the Apple 5300CD was powered by the PowerPC 603 processor, which operated at a speed of 100 MHz. This architecture was a significant shift for Apple, marking its transition to a more powerful and efficient computing platform. The device typically came with 16 MB of RAM, which was expandable up to 64 MB, allowing users to run applications smoothly, even for the demanding software of the time.

One of the standout features of the 5300CD was its display. It featured a 12.1-inch active-matrix LCD monitor, providing vibrant colors and a resolution of 800x600 pixels. This made it suitable for a range of tasks, from word processing to graphic design. The inclusion of a built-in CD-ROM drive was also a highlight, enabling users to access multimedia content and software directly from CDs, a relatively new and powerful feature at that time.

In terms of connectivity, the Apple 5300CD offered a range of ports, including a serial port, a SCSI port for connecting peripherals, and an ADB port for Apple devices. This ensured compatibility with various accessories, such as printers and external storage solutions. The built-in modem facilitated internet access, allowing users to stay connected in an increasingly digital world.

The laptop's design was another noteworthy aspect. It had a compact and lightweight form factor, making it easy to carry, which was essential for users on the go. The significant battery life of around 3 to 5 hours provided the mobility needed for professionals who relied on their devices throughout the day.

While the Apple 5300CD is often remembered for its distinctive design and robust features, it also faced criticism due to its reliability issues, particularly with its logic board. Nonetheless, the model represented an important step in Apple's evolution, paving the way for future portable computing devices.

In conclusion, the Apple 5300CD was a trailblazer in portable computing during the mid-1990s, featuring a powerful processor, a vibrant display, multimedia capabilities, and a compact design. Its introduction underscored Apple’s commitment to innovation and adaptability in the rapidly evolving technology landscape of the time.
