K Service Source Basics Macintosh Performa 630 Series
Basics General Information - 1 General Information The Macintosh Performa 630 Series computers are highperformance, low-cost modular computers with multimedia features, based on the Motorola 68LC040 microprocessor. The computers in this series are designed to accept a floppy drive, a hard drive, and an optional CD-ROM drive.
Basics General Information - 2 Internal Expansion Connections Four types of expansion slots on the logic board include • DRAM SIMM expansion slot (1 or 2 slots) • LC PDS slot • Communications slot for modems and Ethernet found on LC 575 • 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 - 3 IDE (Intelligent Device Electronics) The internal hard drive in the Performa 630 Series computers 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.
Basics General Information - 4 Plastic Panel Design Performa 630 Series computers are 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. You need to remove just one panel to reach either the logic board or drives. Simply remove the front plastic panel (the drive bezel) to service all drives. Remove the plastic I/0 door to slide out the logic board.

The Macintosh Processor Upgrade kit allows 68LC040 computers to switch between a PowerPC 601 processor and a 68LC040 processor.
Upgrades Hook-and Loop Fasteners Processor Upgrade - 2 Macintosh Processor Upgrade with 256K Cache Card 040 Heat Sink The upgrade board includes the PowerPC 601 processor on board and a socket to accept the customer’s 68LC040 processor. Refer to the Macintosh Processor Upgrade manual for information about specifications and troubleshooting.
Upgrades Processor Upgrade - 3 fasteners. If you need to order service replacement parts, order the parts separately. Note: To install the upgrade, you will need a processor removal tool. Order the removal tool as a separate service part. Note: The cache card comes installed on the upgrade board.
Upgrades Processor Upgrade - 4 Installation Procedure Overview There are four basic steps to installing the Macintosh Processor Upgrade.
Upgrades Processor Upgrade - 5 Detailed procedures for this computer follow. Remove the 68LC040 Processor from the Logic Board 1 68LC040 Processor Locate the 68LC040 processor on the logic board.
Upgrades Processor Upgrade - 6 2 Processor Position the teeth of the processor removal tool in the groove between the processor and the logic board socket. Caution: Be sure to lift up on the handle of the processor removal tool. Pressing down could damage components on the logic board. Logic Board Socket N o t e : This graphic shows the proper way to remove any 68LC040 chip from its logic board. Your logic board may differ somewhat from this graphic.
Upgrades Processor Upgrade - 7 3 4 Caution: Pry up each side of the processor only slightly to avoid bending the pins. Gently lift up the processor removal tool handle and pry up each side of the processor from the socket. Remove the processor.
Upgrades Processor Upgrade - 8 Spacer Install the 68LC040 Processor on the Upgrade Board 1 2 Alignment Corners 68LC040 Processor 3 Note: The alignment corner of the 68LC040 processor is missing one pin. The alignment corner of the spacer is missing a pin hole. Position the spacer alignment corner over the 68LC040 processor alignment corner Place the spacer on the processor.
Upgrades Processor Upgrade - 9 4 68LC040 Processor Caution: Forcing the 68LC040 processor connector pins into the socket could damage the pins. If the processor resists installation, check the pin alignment. Caution: Place the upgrade board on a firm even surface to avoid bending the upgrade board when pressing the processor into the socket.
Upgrades Processor Upgrade - 10 Caution: Use two thumbs to evenly distribute the pressure as you press the processor into the socket. 5 Hold the processor and spacer together and position the spacer alignment corner over the upgrade socket alignment corner. Press the processor connector pins into the socket until you hear a “snap.
Upgrades Processor Upgrade - 11 040 Processor Small Gap Spacer Barrel Sockets Note: On a correctly installed 040 processor, a very small gap separates the 040 chip from the metal spacer. A larger gap caused by the barrel sockets of the upgrade board separates the upgrade board and the spacer.
Upgrades Processor Upgrade - 12 Prepare the Upgrade and Logic Boards for Installation Note: The following steps explain how to prepare the logic board to accept the upgrade board. Caution: The EMI clips on the bottom of the logic board are fragile. Do not apply heavy pressure directly to these clips or you may bend the logic board.
Upgrades Processor Upgrade - 13 1 Antistatic Foam Place a piece of antistatic foam directly under the processor socket on the bottom side of the logic board. Note: This step helps prevent the logic board from bending when you apply pressure in the next few steps.
Upgrades Processor Upgrade - 14 2 Battery 3 Lift and rotate the battery one quarter turn from its original position on the logic board. (This step makes room for the upgrade board.) Press the battery firmly into its new position.
Upgrades Processor Upgrade - 15 Install the Upgrade Board Upgrade Connector Alignment Corner Logic Board Socket Alignment Corner 1 Caution: Forcing the upgrade board connector pins into the logic board socket could damage the pins.
