C H A P T E R 2 Architecture The architecture of the PowerBook 1400 computer is designed around two buses: the processor bus and the I/O bus. The processor and memory are connected to the processor bus, which operates at 33.33 MHz. The input and output devices are connected to the I/O bus, a 68030-compatible bus that operates at 25.175 MHz. An Apple custom IC called the PBX IC acts as the bridge between the two buses, translating processor bus cycles into single or multiple I/O bus cycles, as needed.

C H A P T E R 2 Architecture ROM 2 The ROM in the PowerBook 1400 computer is implemented as a 1 M by 32-bit array consisting of two 1 M by 16-bit ROM ICs. The ROM devices support burst mode, so they do not degrade the performance of the PowerPC 603e microprocessor. The ROM ICs provide 4 MB of storage, which is located in the system memory map between addresses $3000 0000 and $3FFF FFFF. The ROM data path is 32 bits wide and addressable only as longwords.

C H A P T E R 3 I/O Features Types of Displays Flat panel displays come in two types: active-matrix and passive matrix. Active-matrix displays, also called thin-film transistor (TFT) displays, have a driving transistor for each individual pixel. The driving transistors give active-matrix displays high contrast and fast response time. Passive matrix refers to a display technology that does not have individual transistors.
C H A P T E R 3 I/O Features Serial Port 3 The PowerBook 1400 computer has a standard Macintosh serial port for synchronous, asynchronous, or AppleTalk serial communication. The 8-pin mini-DIN connector on the back panel is the same as those on other Macintosh computers. Figure 3-5 shows the connector, and Table 3-4 shows the signal assignments for the serial port.
C H A P T E R 3 I/O Features can sink up to 48 mA through each of the pins connected to the SCSI bus. The data and control signals on the SCSI bus are active-low signals that are driven by open drain outputs. Table 3-5 shows the signal assignments for the external SCSI connector. Note that pin 1 of the external SCSI connector is the /SCSI.DISK.MODE signal. Table 3-5 SCSI connector signals Pin number Signal name Pin number Signal name 1 /SCSI.DISK.
C H A P T E R 3 I/O Features Figure 3-6 4 2 ADB connector 3 1 The ADB is a single-master, multiple-slave serial communications bus that uses an asynchronous protocol and connects keyboards, graphics tablets, mouse devices, and other devices to the computer. The custom ADB microcontroller drives the bus and reads status from the selected external device. A 4-pin mini-DIN connector connects the ADB controller to the outside world. Table 3-6 lists the ADB connector pin assignments.
C H A P T E R 3 I/O Features For LocalTalk operation, the IR module takes serial bits from the SCC and transmits them using a modified form of pulse encoding called PPM-4. This method of encoding uses four cycles of a 3.92 MHz carrier for each pulse, which increases the system’s immunity to interference from fluorescent lights. Sound System 3 The 16-bit stereo audio circuitry provides high-quality sound input and output through the built-in microphone and speaker.
C H A P T E R 3 I/O Features Note The sound input jack accepts the maximum sound output of an audio CD without clipping. When working with sound sources that have significantly lower levels, you may wish to increase the sound output level. You can do that using the Sound Manager as described in Inside Macintosh: Sound. ◆ Stereo sound signals from the expansion bay go through an analog multiplexer that selects either those signals or the line signals from the external input jack.

Table 4-6 38 Signals on the CD-ROM connector Signal name Signal description /CS1FX IDE register select signal. It is asserted low to select the main task file registers. The task file registers indicate the command, the sector address, and the sector count. /CS3FX IDE register select signal. It is asserted low to select the additional control and status registers on the IDE drive.
C H A P T E R 4 Expansion Modules Unused Signals 4 Several signals defined in the standard interface for the IDE drive are not used by the expansion bay. Those signals are listed in Table 4-7 along with any action required for the device to operate in the expansion bay. Table 4-7 Unused IDE signals Signal name Comment DMARQ No action required. CSEL This signal must be tied to ground to configure the device as the master in the default mode.
C H A P T E R 4 Expansion Modules 4. When the expansion bay power goes high, the Baboon IC generates another interrupt. 5. System software responds to the power-on interrupt and asserts a signal to enable the IDE bus in the expansion bay. 6. The software then releases the /MB_IDE_RST signal from the Power Manager IC, allowing the IDE device to begin operating. Essentially the reverse sequence occurs when a module is removed from the expansion bay: 1.

IMPORTANT Space limitations require devices used on the user-installed RAM expansion cards to have TSOP (thin small outline package) rather than SOP or SOJ packages. ▲ Note The DRAM refresh operation depends on the state of the computer.
C H A P T E R 4 Expansion Modules Mechanical Design of the RAM Expansion Cards 4 The PowerBook 1400 computer accepts two types of RAM expansion cards: one factory-installed card and up to two user-installed cards. Design of the User-Installed RAM Card 4 Figure 4-6 shows three views of the user-installable RAM expansion card. Two of these cards can be installed, one above the other, by plugging the second card into the receptacle on the first card.

C H A P T E R 4 Expansion Modules PC Card Features 4 The PC card slot supports two types of PC cards: mass storage cards such as SRAM and ATA drives (both rotating hard disk and flash media) and I/O cards such as modems, network cards, and video cards. The Macintosh desktop metaphor includes the concept of storage device representation, so it already supports mass storage cards. Apple Computer has extended the metaphor to include I/O cards as well.
C H A P T E R 4 Expansion Modules Each window has a 64 MB address space. The window address spaces could be implemented as 8 MB pages in some systems. The PC card interface has the ability to map the entire PC card’s memory space into the host system’s memory window. Each window has its own independent access timing register. Data Access 4 Each socket supports both byte and word data access in both memory and I/O modes.
C H A P T E R 4 Expansion Modules Controller Interrupts There is a single interrupt for both sockets. The interrupt is a combination of the status change signal and the PC card’s interrupt request signal.

C H A P T E R 5 Software Features This chapter describes the new features of the software for the PowerBook 1400 computer. It describes the built-in ROM and the system software that resides on the hard disk. A separate section describes Open Transport, Apple Computer’s new standard for Macintosh networking and communications, now available on a PowerBook model for the first time.
C H A P T E R 5 Software Features Modified Software Components 5 Version 7.5.3 of the system software includes several changed components, listed here along with some of the changes. Apple Guide 5 The new version 2.0 of Apple Guide has the following changes: ■ It runs in native mode on Macintosh computers equipped with PowerPC microprocessors. ■ It corrects several bugs, including one that formerly caused problems displaying coach marks in modal dialog boxes. ■ It now defaults to U.S.
C H A P T E R 5 Software Features ■ Persistent RAM disk File Sharing 5 The new File Sharing version 7.5.2 has the following changes: ■ It supports shared files on removable disks appropriately when the disks are inserted and removed. ■ It corrects a few bugs, including one that formerly caused certain files not to be copied. Finder 5 The Finder has the following changes: ■ It maintains comments in Get Info windows when it rebuilds the desktop.
C H A P T E R 5 Software Features Monitors & Sound 5 The Monitors & Sound control panel on the PowerBook 1400 computer is new to the PowerBook computers. It combines the functions formerly provided by three separate control panels: Monitors, Sound, and PowerBook Display. Native Resource Manager 5 The version of the Native Resource Manager in the PowerBook 1400 computer is an improved version of the one in the system software that came with the Macintosh PowerBook 5300. Open Transport 5 Version 1.
C H A P T E R 5 Software Features ■ MathLib ■ Mount IDE Drive ■ PowerBook 150 Update ■ PowerBook 5300 Enabler ■ PowerBook 5300/190 Enabler ■ PowerPC Enabler ■ PowerPC Finder Update ■ SCSI Manager ■ SCSI Manager 4.
C H A P T E R 5 Software Features addition to being consistent with industry standards, Streams-based DLPI drivers provide higher performance than .ENET-style drivers. Apple Computer’s Open Transport software includes new stack implementations for AppleTalk and MacTCP. Apple expects that third parties will provide implementations of DECnet™, IPX, and other network protocols. The Open Transport implementation of TCP/IP is a replacement for MacTCP.
