Basics General Information - 2 General Information Macintosh LC 630 and Macintosh Quadra 630 Computers The Macintosh LC 630 and Macintosh Quadra 630 computers are high- performance, low-cost modular computers with multimedia features. The LC 630 uses the Motorola 68LC040 processor. The Quadra 630 uses the Motorola 68040, which includes a floating point unit. The computers ship with the manual insert floppy drive, an IDE hard drive, and an optional trayloading CD-ROM drive.
Basics General Information - 3 Macintosh LC 630, DOS-Compatible The LC 630 DOS-Compatible computer adds to the basic 630 design the ability to simultaneously run the Macintosh operating system and PC application programs. The DOSCompatible computer ships with three boards and a DRAM SIMM installed on the main logic board. The three boards are the DOS-compatible board, a daughterboard for sound, and a DOS-Compatible adapter board in the Processor Direct Slot (PDS).
Basics General Information - 4 Performa 640 DOS-Compatible The Performa 640 DOS-Compatible is based on the Macintosh LC 630-DOS Compatible computer. The Performa 640 DOS-Compatible is bundled with a 500 IDE hard drive and the trayloading double-speed CD-ROM drive. As you go through this manual, consider the Macintosh LC 630 DOS-Compatible information as applicable to the Performa 640 LC DOS-Compatible unless specified otherwise.
Basics General Information - 5 User Controls User controls include: • Soft power-on control from keyboard • Front panel sound-control push buttons • Optional infrared remote control
Basics General Information - 6 Internal Expansion Connections Four types of expansion slots on the logic board include: • DRAM SIMM expansion slot (1 or 2 slots) • LC PDS slot (already populated in the LC 630 DOSCompatible). • Communications slot for modems and Ethernet • Video-in slot for real-time video display, capture, and overlay In addition to expansion slots on the logic board, there is an expansion ribbon connector for an optional TV tuner card.
Basics General Information - 7 IDE (Intelligent Device Electronics) The internal hard drive uses IDE (Intelligent Device Electronics) technology, commonly used in DOS-compatible systems. The internal IDE hard drive functions the same as a typical SCSI hard drive. You must replace IDE drives like for like. The IDE drive does not affect SCSI ID selections or SCSI termination schemes. Seven external SCSI devices may be daisy chained through the external SCSI port.
Basics General Information - 8 Plastic Panel Design The computer is designed for easy service. Plastic panels cover the metal bottom case, the metal top cover shield, and the left, right, and rear sides of the metal case. To service the logic board, simply remove the rear plastic panel and slide out the logic board. To access the drives, simply remove the front plastic panel.
