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.
User Controls
User controls include
• Soft power-on control from keyboard
• Front panel sound-control push buttons
• Optional infrared remote control
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. The TV-tuner connector provides NTSC and PAL input from an external TV antenna or cable.

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. Seven external SCSI devices may be daisy-chained through the external SCSI port on the Performa 630 Series.

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.

General
The Symptom Charts included in this chapter will help you diagnose specific symptoms related to your product. Because cures are listed on the charts in the order of most likely solution, try the first cure first. Verify whether or not the product continues to exhibit the symptom. If the symptom persists, try the next cure. (Note: If you have replaced a module, reinstall the original module before you proceed to the next cure.)
If you are not sure what the problem is, or if the Symptom Charts do not resolve the problem, refer to the Flowchart for the product family.
For additional assistance, contact Apple Technical Support.
