Apple Service Source: case width and depth were transposed across the 630 family (Apple: 16.5 in W x 12.6 in D); sound is 8-bit MONO input and 8-bit stereo output (16-bit only in CD mode), not 16-bit stereo in and out; added Apple's 45 W supply rating, 1 MB ROM, the two logic-board SIMM variants 661-0158 (36 MB) and 661-1114 (52 MB), the no-internal-SCSI statement and the slot pinouts; recorded that Apple's own volume misprints maximum power as 5 W
Rewrite on Apple's spec sheet and the 630 Series Service Source: battery is 4.5 V alkaline per Apple (5.4 is a misprint; vinegar, not bicarbonate); one ADB port, not two; configurations from Apple's product configuration pages; symptom charts; Commons photo of an actual Performa 630; drop uncited bundle claims

The Performa 630 Series volume prints the maximum power as "5 W, not including monitor"; Apple's specification sheet and the LC 630/Quadra 630/Performa 640 volume give 45 W.<ref name="ss" /><ref name="apple" /><ref name="sslc" /> The same volume says the external SCSI port takes up to six devices in its specifications and seven in its general information.<ref name="ss" />
 
== Hardware ==
Low End Mac describes the 630 family as the first desktop Macintoshes with an IDE hard drive; the CD-ROM drive, when fitted, is SCSI.<ref name="lem">{{cite web |url=https://lowendmac.com/1994/performa-630/ |title=Performa 630 and LC 630 |publisher=Low End Mac |access-date=2026-09-30}} First desktop Mac with an IDE hard drive; CD-ROM is SCSI; LC and Performa 630 have no FPU, which can be added by replacing the 68LC040 with a 68040; one SIMM socket; PRAM battery 4.5 V alkaline; upgrade paths: PowerPC PDS card and 6300-series logic board.</ref> Apple says IDE drives must be replaced like for like, and that the IDE drive does not affect SCSI IDs or termination.<ref name="ss" /> The logic board slides out of the back once the plastic I/O door is removed, and the drives come out from the front after the drive bezel.<ref name="ss" />
 
The 68LC040 has no FPU; Low End Mac notes that one can be added by fitting a full 68040 in its place.<ref name="lem" /> Apple's upgrades were the Macintosh Processor Upgrade, a PowerPC 601 card with a 256K cache card that lets the machine switch between the 601 and its 68LC040, and the Power Macintosh 5300/6300 logic board upgrade with a 100 MHz 603e.<ref name="ss" />
 
=== Battery ===
Apple's specification sheet gives the battery as 4.5 V alkaline, and Low End Mac agrees.<ref name="apple" /><ref name="lem" /> The Service Source names no battery part and no test voltage. Its symptom charts tell the technician to "Unplug 5.4 battery, wait 20 seconds, plug in battery, and restart computer"; "5.4" is a misprint for 4.5, which the LC 630 volume prints for the same step.<ref name="ss" /><ref name="sslc" /> Fitting the Processor Upgrade involves lifting the battery and turning it a quarter turn on the board.<ref name="ss" /> Leakage from an alkaline pack is neutralised with a weak acid such as vinegar; see [[Battery Explosion, Capacitor or Corrosion Damage]].

Specifications

Performa 630 series specifications (Apple)
Item Specification
Processor Motorola 68LC040 at 33 MHz; 32-bit registers, address and data buses[4]
RAM 4 MB built in; 36 MB maximum on a logic board with one SIMM slot (part 661-0158), 52 MB on a board with two (661-1114: one ordinary slot and one single-sided slot)[4]
ROM 1 MB[4]
Video 1 MB DRAM frame buffer, not expandable; up to 16 bits per pixel on Apple 12- to 14-inch monitors, the 15-inch multiple-scan and VGA (640 × 480); up to 8 bits on the Apple 16-inch and SVGA (800 × 600)[4]
Drives 1.4 MB SuperDrive, manual insert; 250 MB IDE hard drive; optional AppleCD 300i Plus. Internal SCSI hard drives are not supported[4]
Ports Two RS-232/422 serial (mini DIN-8); one external SCSI (DB-25); one ADB (mini DIN-4); DB-15 monitor port on the video daughterboard[4]
Sound 8-bit mono input (microphone or line level, with bias current for an electret microphone); 8-bit stereo output, 16-bit in CD mode, 0.5 V RMS into 39 ohms, front and rear jacks[4]
Slots 114-pin LC processor-direct slot; 112-pin communications slot; 60-pin video-in slot; 10-pin TV tuner port[4]
Controls Soft power from the keyboard; front-panel volume buttons; optional infrared remote[4]
Electrical 100-240 V AC, 50-60 Hz; 45 W maximum, not including the monitor[1][5]
Size and weight 10.95 × 41.95 × 32 cm; 7.7 kg (17 lb) without CD-ROM drive, 8.6 kg (19 lb) with[4]

The Performa 630 Series volume prints the maximum power as "5 W, not including monitor"; Apple's specification sheet and the LC 630/Quadra 630/Performa 640 volume give 45 W.[4][1][5] The same volume says the external SCSI port takes up to six devices in its specifications and seven in its general information.[4]

Hardware

Low End Mac describes the 630 family as the first desktop Macintoshes with an IDE hard drive; the CD-ROM drive, when fitted, is SCSI.[6] Apple says IDE drives must be replaced like for like, and that the IDE drive does not affect SCSI IDs or termination.[4] The logic board slides out of the back once the plastic I/O door is removed, and the drives come out from the front after the drive bezel.[4]

The 68LC040 has no FPU; Low End Mac notes that one can be added by fitting a full 68040 in its place.[6] Apple's upgrades were the Macintosh Processor Upgrade, a PowerPC 601 card with a 256K cache card that lets the machine switch between the 601 and its 68LC040, and the Power Macintosh 5300/6300 logic board upgrade with a 100 MHz 603e.[4]

Battery

Apple's specification sheet gives the battery as 4.5 V alkaline, and Low End Mac agrees.[1][6] The Service Source names no battery part and no test voltage. Its symptom charts tell the technician to "Unplug 5.4 battery, wait 20 seconds, plug in battery, and restart computer"; "5.4" is a misprint for 4.5, which the LC 630 volume prints for the same step.[4][5] Fitting the Processor Upgrade involves lifting the battery and turning it a quarter turn on the board.[4] Leakage from an alkaline pack is neutralised with a weak acid such as vinegar; see Battery Explosion, Capacitor or Corrosion Damage.

From Apple's symptom charts

Symptom Apple's cures, in order
Eight-tone error chord at start-up Reseat the SIMMs; replace the SIMMs; replace the logic board[4]
Four-tone error chord at start-up Disconnect the hard drive power cable and restart (if normal, test and replace the drive); disconnect the floppy cable and restart (if normal, replace the floppy drive); replace the logic board[4]
Screen completely dark, fan not running, LED off Check the power connections; the machine powers on only from the keyboard, so try a known-good keyboard; reseat the logic board; unplug the battery for 20 seconds; check the monitor has power; remove cards and peripherals; replace the power supply, then the logic board[4]
Menu bar flashes or the system keeps beeping Check the front-panel buttons are not jammed; reseat the drive bezel and front panel control board[4]
Crackling sound outside play-through mode Audio Volume Extension 1.1 or later; replace the logic board[4]
Rattling at start-up with the Apple External Video Connector Fold the external video cable away from the fan blades[4]

The start-up chords and Sad Mac codes are on Sad Mac Error Codes.
