Overview
Released
Released	1995	1989
Performance
Processor
Processor	PowerPC 603e 100 MHz (Macintosh Performa 6300CD)	68000 8 MHz (Macintosh SE)
CPU cores
CPU cores	1	1
Memory
Memory	16 MB (better)	1 MB or 2 MB
Storage
Storage	1.2 GB (better)	20 MB to 40 MB
CPU
CPU	100 MHz PowerPC 603e with integrated floating-point unit, 32 KB L1 cache, 256 KB L2 cache and 64-bit data path at 40 MHz	MC68000 with 32-bit internal architecture at 7.83 MHz in the original exact FDHD brochure and service manual. Current Apple support rounds the clock to 8 MHz and specifies a 16-bit data path; the existing nominal 8 MHz SE chip record is reused. No FPU, PMMU, L1 or L2 cache, or second processor.
GPU
GPU	Integrated 1 MB DRAM video supports 640 × 480 at 16-bit colour or 832 × 624 at 8-bit colour through the DB-15 monitor port	–
Memory type
Memory type	Two 72-pin SIMM slots; 16 MB minimum and 64 MB maximum with 80 ns memory	Exact ordering configurations have 1 MB for dual-FDHD and 20 MB hard-disk systems, or 2 MB for the 40 MB hard-disk system; expandable to 4 MB. Four 30-pin SIMM sockets, 150 ns or faster, using 256 KB or 1 MB modules installed in pairs; two-chip 1 MB SIMMs are unsupported. No soldered system RAM. 256 KB ROM includes the FDHD drive routines, Hierarchical File System, QuickDraw, Macintosh Toolbox, AppleTalk, ADB and SCSI support. 256 bytes of parameter memory.
Storage type
Storage type	1.2 GB internal IDE hard drive, 1.44 MB floppy drive and 4× CD-ROM drive	Original August 1989 maker brochure explicitly offers M0029LL/A with 1 MB RAM and two 1.4 MB FDHD floppy drives; M0028LL/A with 1 MB, one FDHD drive and 20 MB internal SCSI hard disk; M0031LL/A with 2 MB, one FDHD drive and 40 MB internal SCSI hard disk. Current support calls the FDHD capacity 1.44 MB. Drive reads and writes 400 KB and 800 KB Macintosh disks as well as high-density Macintosh disks, and exchanges MS-DOS, OS/2 and ProDOS-format disks with Apple File Exchange. Capacities are retained in their original units; fixed-storage headline is omitted for the floppy-only configuration. No CD-ROM included.
Expansion slots
Expansion slots	Macintosh LC processor-direct slot, communications slot, TV-tuner bay and video input/output slot	One SE-Bus processor-direct expansion slot with a 96-pin Euro-DIN connector and accessory access opening. Original exact brochure explicitly says SE/30 and NuBus cards are incompatible with this slot. Compatible optional accelerator, network, coprocessor and external-display adapter cards require their own software and hardware.

Display type
Display type	–	Built-in 9-inch, one-bit monochrome CRT at 512 × 342. Exact brochure, service manual and current support's explicit note agree; the generic current support table's 512 × 384 row is not adopted. No refresh rate is published in the sources read.
Connections
Ports
Ports	Headphone jack	Headphone jack
Back ports
Back ports	DB-15 monitor output, Apple Desktop Bus, external DB-25 SCSI, two serial connectors, microphone input and stereo sound output	Two ADB ports; printer and modem RS-232/RS-422 serial ports with mini-DIN-8 connectors and up to 230.4 Kbaud in the original brochure; external DB-25 SCSI; DB-19 external floppy connector; sound output for an external amplifier or speaker. AppleTalk/LocalTalk networking uses the serial ports. No built-in Ethernet, USB, FireWire, microphone input or computer-monitor video connector.
External displays
External displays	–	No built-in external-video output. An optional compatible SE-Bus external-display adapter is required; its display modes and limits are not assigned to the standard machine.
Speakers
Speakers	–	Built-in sound with a four-voice generator, 8-bit digital-to-analogue conversion and 22 kHz sampling rate. One miniature sound-output port for an external amplifier; no stereo or measured loudness claim assigned.
Keyboard and mouse
Keyboard and mouse	–	Exact ordering brochure supplies the mouse, system software, HyperCard, Guided Tour disk, owner's guide, Getting Started guide and warranty statement. Apple Keyboard or Apple Extended Keyboard is packaged and sold separately, not assumed included. The primary is the original FDHD-labelled maker brochure photograph of the single-floppy/hard-disk housing.

Size and weight detail
Size and weight detail	Apple lists 4.3 × 12.6 × 16.5 inches and 19 lb for the Quadra 630 form factor	Exact original FDHD brochure and shared service manual give 34.5 × 24.4 × 27.6 cm (height × width × depth), also printed as 13.6 × 9.6 × 10.9 inches. Current exact support instead prints a 9.69-inch width; original maker metric values are used without converting the differently rounded inch values. Weight is 7.7–9.5 kg / 17–21 lb depending on fitted hard disk or second floppy drive; no one configuration-specific weight is established, so headline mass remains omitted.
Power supply
Power supply	Maximum 55 W; 110–240 V AC at 50–60 Hz; 4.5 V alkaline clock battery	Exact original brochure and shared service specify 100 W maximum, regional 90–140 or 170–270 V AC, 47–63 Hz. Current support summarises 90–270 V and 0.83 A. Maximum input is not typical operating consumption. Brochure describes a CMOS clock/calendar with a seven-year lithium battery; no guessed battery chemistry capacity is added.
Noise
Noise	–	Original exact brochure rates the cross-flow fan at 10 CFM and 38 dB without acoustic distance or weighting; this is not a measured whole-computer noise figure.
In the box
In the box	Original System Software 7.5.1. Apple lists 16 October 1995 as introduction; a separate first-sale date was not established.	System Tools 6.0.3 or later with Finder 6.1 or later, printer drivers, Apple File Exchange, HD SC Setup, Disk First Aid and Font D/A Mover; HyperCard included. Exact August 1989 current ordering brochure establishes sale in 1989, without proving first-sale month or day; Apple's introduction date is 1 August 1989. This is the FDHD hardware revision, distinct from the published original 1987 SE with 800 KB drives. Linked 1988 SE owner's guide covers the earlier 800 KB edition and must be read with the separately linked FDHD supplement; it is not specification evidence for this revision's drive capacity. No unsupported official predecessor link assigned.
