C H A P T E R 1 Hardware This chapter describes the major features of the Macintosh PowerBook 165c computer, emphasizing the similarities and differences between it and other Macintosh PowerBook computers. IMPORTANT Only the major differences between the PowerBook 165c and the PowerBook 160/180 are described in detail here. For a complete understanding of the PowerBook 165c computer, refer to the Macintosh PowerBook 160 and Macintosh PowerBook 180 Developer Note.
C H A P T E R 1 Hardware ■ Floppy disk: one internal 1.4 MB Apple SuperDrive with Super Woz Integrated Machine (SWIM) interface. ■ Hard disk: one internal 2.5-inch SCSI hard disk drive. Disk capacities of 80 and 120 MB are offered. ■ SCSI disk mode: by connecting an HDI-30 SCSI Disk Adapter cable, users can access the PowerBook’s internal hard disk from another Macintosh.

C H A P T E R 1 Hardware Compatibility Issues 1 Because the Macintosh PowerBook 165c is identical in most respects to the Macintosh PowerBook 160/180 computers, most hardware and software designed for those models will operate without modification on the PowerBook 165c. This section highlights key areas you should investigate in order to ensure that your products work properly with the PowerBook 165c. These topics are covered in more detail in subsequent sections.
C H A P T E R 1 Hardware Hardware Overview 1 This section discusses the hardware differences between the Macintosh PowerBook 165c and the Macintosh PowerBook 160/180 computers. IMPORTANT Memory sizes, addresses, and other data are specific to each type of Macintosh computer and are provided for informational purposes only.

C H A P T E R 1 Hardware The RAM expansion slot is located on the RAM/ROM board, and supports up to 10 MB of PSRAM, for a total of 14 MB. See the “RAM Expansion Interface” section on page 10 for information about designing RAM expansion cards. RAM is always contiguous because only one size of RAM chip (4 Mbits) is used. As a result, software does not have to “stitch” memory.
C H A P T E R 1 Hardware the WD90C26 manages its frame buffer differently than QuickDraw expects, Pangola must perform byte packing and unpacking to support color modes other than 8-bit. For example, in 1-bit mode QuickDraw expects that each byte in the frame buffer represents eight pixels. For every byte QuickDraw writes to the frame buffer in 1-bit mode, Pangola unpacks the bits and sends 8 bytes to the WD90C26.

C H A P T E R 2 Software This chapter describes the new ROM and system software features of the PowerBook 165c computer. ROM Software 2 The PowerBook 165c uses the same ROM software as the PowerBook 160/180 computers. Support for the color display is provided by the video driver located in the declaration ROM. All other software modifications are incorporated into the system software. System Software 2 The PowerBook 165c computer is shipped with System 7.1 software.
