The '''Macintosh Performa 630''' is a consumer-oriented personal computer manufactured by Apple Computer and released on July 18, 1994.<ref>{{cite web |url=https://support.apple.com/en-us/112345 |title=Macintosh Performa 630 and 630CD: Technical Specifications |publisher=Apple Inc. |access-date=2026-02-10}}</ref> It is a rebrand of the [[Macintosh LC 630]] for the consumer retail market, featuring a 68LC040 processor without a floating-point unit.

The Performa 630 was the base model in the 630 series, shipped without a CD-ROM drive. It was bundled with a 14-inch Apple Performa Display Plus, keyboard, mouse, and consumer-oriented software including ClarisWorks, At Ease, and Quicken.<ref>{{cite web |url=https://lowendmac.com/1994/performa-630/ |title=Performa 630 and LC 630 |publisher=Low End Mac |access-date=2026-02-10}}</ref>

== Model Variants ==
The Performa 630 was part of a large family of consumer models based on the [[Macintosh LC 630]]:
* [[Macintosh Performa 630CD|Performa 630CD]] – Added 2× CD-ROM drive
* [[Macintosh Performa 631CD|Performa 631CD]] – 8 MB RAM, 500 MB HD, bundled with modem and display
* [[Macintosh Performa 635CD|Performa 635CD]] – 5 MB RAM, CD-ROM, modem, and display bundle
* [[Macintosh Performa 636|Performa 636]] – Higher-education market variant
* [[Macintosh Performa 636CD|Performa 636CD]] – 636 with CD-ROM
* [[Macintosh Performa 637CD|Performa 637CD]] – 636CD with display bundle
* [[Macintosh Performa 638CDV|Performa 638CDV]] – Added TV tuner/video input card
* [[Macintosh Performa 640CD DOS Compatible|Performa 640CD DOS Compatible]] – With Intel 486DX2 DOS card

== Architecture and Processor ==
The Performa 630 uses a Motorola 68LC040 processor running at 33 MHz. Unlike the [[Macintosh Quadra 630|Quadra 630]] which uses a full 68040, the LC and Performa variants lack the integrated floating-point unit (FPU). The processor can be replaced with a full 68040 to add FPU functionality.

The system bus operates at 33 MHz. The 630 includes 1 MB of ROM.

== Memory and Storage ==
=== RAM Configuration ===
The Performa 630 ships with 4 MB of RAM soldered to the logic board. A single 72-pin SIMM socket allows expansion up to 36 MB total (4 MB onboard + 32 MB SIMM). 80 ns non-parity SIMMs are required.<ref>{{cite web |url=https://everymac.com/systems/apple/mac_performa/specs/mac_performa_630.html |title=Macintosh Performa 630 Specs |publisher=EveryMac.com |access-date=2026-02-10}}</ref>

=== Storage Systems ===
The Performa 630 was the first desktop Macintosh to use an IDE hard drive interface rather than SCSI, reducing manufacturing costs. The system includes a 250 MB IDE hard drive and a 1.44 MB SuperDrive floppy.

An external SCSI port remains available for peripherals.

== Display and Graphics ==
The system includes 1 MB of dedicated DRAM for video (non-upgradeable). Supported resolutions:
* 512×384, 640×480: 16-bit color (thousands of colors)
* 800×600, 832×624: 8-bit color (256 colors)

An LC PDS video card can be added for higher resolutions or a second display.

== Input/Output and Expansion ==
=== Port Configuration ===
* 2× ADB ports (keyboard, mouse)
* 2× Serial ports (DIN-8, RS-422)
* 1× External SCSI (DB-25)
* 1× DA-15 video output
* 1× Headphone jack (front panel)
* Front panel volume controls

=== Expansion Slots ===
* 1× LC PDS slot
* 1× Comm slot (modem/ethernet)
* 1× Video slot (video input/output card)
* 1× TV tuner slot
