CPU
CPU	Macintosh 68LC040, with 66/33 MHz clock notation: CPU execution and bus at 33 MHz, doubled internal clock at 66 MHz. AppleFacts April 1995 and the later Apple Memory Guide identify 68LC040; the LC 630 DOS technical booklet and shared Service Source instead print 68040 and the booklet claims an FPU. That disagreement is retained rather than assuming a standard Macintosh FPU. The separate DOS card contains a 66 MHz Cyrix Cx486DX2 or Intel 80486DX2, both explicitly supported by the exact developer note; this is not a pair of matching Macintosh CPUs	Motorola MC68040 with integrated floating-point unit, paged memory management and 8 KB cache. Apple gives nominal 33 MHz in its support table and October 1994 catalogue; its developer note explains the 33 MHz bus and 66 MHz internal clock. The LC 630 and Performa 630 use the FPU-less MC68LC040 instead
GPU
GPU	Macintosh video uses a fixed 1 MB DRAM frame buffer with no video-memory expansion. DOS card has separate 512 KB DRAM and VGA controller. PC environment supports VGA 640 × 480 and SVGA 800 × 600 plus legacy EGA/CGA/MDA. Shared-display colour modes and resolution depend on environment and driver	Built-in video with 1 MB dedicated DRAM, 16-bit colour at 640 × 480 or 512 × 384 and 8-bit at 800 × 600 or 832 × 624; video capture not supported at 832 × 624
Memory type
Memory type	8 MB Macintosh RAM: 4 MB soldered and a 4 MB SIMM, with two 72-pin 80 ns SIMM sockets. Maximum 52 MB on the main logic board using 32 MB and 16 MB SIMMs; the second socket accepts 1, 4 or 16 MB. PC card has its own 4 MB 72-pin SIMM, expandable to 32 MB, or can use a selected portion of Macintosh RAM; those independent pools are not added to the headline Macintosh RAM	4 MB on the logic board and one 72-pin SIMM slot; Apple catalogue offers 4 MB or 8 MB configurations and supports up to 36 MB using a 32 MB SIMM. Minimum SIMM speed is 80 ns; 1 MB ROM
Storage type
Storage type	Original AppleFacts configuration includes 500 MB IDE hard disk, manual-insert 1.4 MB SuperDrive and internal CD-ROM. Shared Service Source identifies double-speed AppleCD 300i Plus; the exact technical booklet also permits a configuration without the CD-ROM drive. Internal IDE and external SCSI are separate interfaces; no internal SCSI drive inferred	250 MB internal IDE hard disk and 1.44 MB SuperDrive floppy. A double-speed internal SCSI CD-ROM drive is optional, not standard on the base Quadra. Other hard-disk capacities in the shared family developer note are not copied into these exact Quadra configurations
Expansion slots
Expansion slots	DOS hardware occupies the Macintosh processor socket and LC-compatible PDS. Separate communications slot accepts optional modem or Ethernet; video-input slot and TV-tuner connector remain available. Original main DOS board, sound daughterboard and game-adaptor board are distinct components. Performa 630/640 DOS Compatible bundles use this family design; ordinary LC 630 and Quadra 630 are separate records	LC-compatible processor-direct slot, communications slot for either Ethernet or modem, video-input slot and optional TV tuner. Apple Video and TV/Video kits add capture and television features; they are not built into the base configuration. Optional PowerPC processor upgrade

Back ports
Back ports	One ADB, DB-15 monitor, DB-25 external SCSI, two mini-DIN-8 RS-232/RS-422 serial ports, sound input and rear sound output. DOS adaptor adds a DB-15 PC game-controller connector. Supports up to six external SCSI devices; no built-in Ethernet	DB-15 video, DB-25 external SCSI, one ADB, two serial ports with LocalTalk, sound input and rear sound output. Front headphone jack and infrared receiver; no USB. Ethernet uses an optional communications card
External displays
External displays	Separate compatible display needed. Macintosh output supports 640 × 480 at 16-bit colour and 800 × 600 at 8-bit; exact developer note describes a single shared monitor and environment switching. Original AppleFacts staged setup photographs include an external Apple monitor and keyboard/mouse; pictured accessories are not included in the computer dimensions or weight	Requires a separate monitor; Apple lists Color Plus 14-inch, Macintosh Color Display, AudioVision 14 and Multiple Scan 15 plus compatible VGA/SVGA displays. The maker catalogue photo includes an external monitor, keyboard and mouse
Speakers
Speakers	Macintosh sound input is 8-bit mono; output 8-bit stereo or 16-bit stereo CD playback. Built-in speaker is muted by either sound-output jack. Included Sound Blaster 16-compatible PC sound card outputs through Macintosh speaker/headphones; the PC environment cannot send or receive serial MIDI according to the exact Apple Read Me	Single internal speaker, stereo output and front/rear audio jacks. Apple developer note specifies 8-bit sampling; a contemporary MacUser review calls output 16-bit, so maker specification retained
Keyboard and mouse
Keyboard and mouse	ADB keyboard and mouse supported; original staged photographs show an external monitor, keyboard and mouse. Performa bundles may include these accessories and software according to their regional configuration; exact LC 630 DOS supplied bundle is not established by the recovered worldwide AppleFacts entry	–

Size and weight detail
Size and weight detail	Exact Apple technical booklet publishes 320 mm wide × 419.5 mm deep × 109.5 mm high. 8.6 kg with CD-ROM, 7.7 kg without; weight varies with installed options. Shared Service Source swaps width/depth labels, so the exact technical booklet dimensions are retained	October 1994 AppleFacts gives 10.9 cm high, 32.0 cm wide and 41.9 cm deep; metric values retained. Shared Service Source reverses width and depth (41.95 cm width, 32 cm depth), an unresolved documentation conflict. Base weight without CD-ROM is 7.7 kg; with CD-ROM is 8.6 kg, varying with options. AppleFacts' 8.6 kg reference does not identify its drive configuration
Power supply
Power supply	100–240 V AC, 50–60 Hz; 45 W maximum excluding monitor, as published in exact technical booklet and shared Service Source. DOS card 10 W maximum is a subsystem rating, not added to the 45 W headline. Macintosh clock/calendar has a battery	100–240 V AC, 50–60 Hz; 45 W maximum excluding monitor, according to Service Source. 4.5 V alkaline clock battery
In the box
In the box	Mac OS and PC environment operate concurrently, with only the active environment receiving input. PC Setup switches environments, shares folders and configures drive-container files. Original AppleFacts identifies MS-DOS 6.2 and Windows 3.1 support. First actual retail sale has not been established from the recovered maker records, so released is omitted	System 7.1.2P with System Enabler 405. Apple introduces the model on 18 July 1994; contemporary TidBITS states planned 2 August shipping for the Quadra, distinct from the education-market Performa. October 1994 maker buying catalogue confirms the Quadra was offered during 1994; exact first-delivery date remains unconfirmed, so release uses year precision
