DISCUSSION

    On May 30, 1995, Apple Japan introduced the PowerBook 550c. The PowerBook 550c features five major changes over the previous PowerBook 500 series computers:
    • Uses 66/33 MHz 68040 microprocessor with built-in Floating Point Unit (FPU) - also called a math coprocessor.
    • Includes 750 MB internal hard disk drive
    • Uses 10.4 inch (264 mm) active matrix color display
    • Weighs 6.8 lbs (3.1 kg). Approximately 7 oz. (200 gm) lighter than the PowerBook 540c.
    • The entire unit is a dark grey (versus the current duo tone color).
    Also, since this is a Japanese Macintosh PowerBook 500 series computer, the keyboard has a Japanese Industrial Standard (JIS) layout.

    Microprocessor

    66/33-MHz 68040 microprocessor (with FPU). (the two speeds refer to the internal processor and bus interface, respectively)
    32-bit Address and Data bus
    Daughterboard (memory expansion) has a 32-bit bus running at 33MHz

    RAM
    • 4 MB RAM on logic board.
    • Expandable to 36 MB with 70ns low power self-refreshing RAM (Apple 8 MB RAM Expansion Kit, or Third Party higher density RAM card)
