CPU
CPU	Motorola MC68LC040 without an integrated floating-point unit; paged memory management and 8 KB cache. Nominal 33 MHz bus clock and 66 MHz internal clock, as Apple explains in its exact Japanese specifications and developer note. Optional PowerPC processor upgrade is separate from this original model	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	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	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	Original model has 4 MB soldered RAM and one 72-pin SIMM slot, expandable to 36 MB; 4 MB and 8 MB configurations in the October 1994 catalogue. Japanese configurations have 8 MB. 80 ns or faster SIMMs and 1 MB ROM. Later shared service-manual boards and DOS Compatible variants have different memory arrangements	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	250 MB internal IDE hard disk in the original configurations, plus 1.44 MB SuperDrive floppy. Japanese maker lists 8 MB/250 MB versions with or without the double-speed AppleCD 300i Plus internal SCSI CD-ROM. April 1995 catalogue adds 350 MB disks without establishing exact RAM/CD pairings, so those configurations are not inferred. LC 630 DOS Compatible is a different dual-processor model	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	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	LC-compatible processor-direct slot, communications slot for either Ethernet or modem, video-input slot and optional TV tuner.

Speakers
Speakers	Single internal speaker; 8-bit stereo sound output and monophonic recording, with 16-bit stereo CD playback. Front and rear headphone outputs cannot be used simultaneously. The Japanese specifications and shared service manual distinguish CD playback from ordinary sound output	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

Size and weight detail
Size and weight detail	Original Japanese Apple specifications give 109.5 mm high, 320 mm wide and 419.5 mm deep; these exact metric values retained. October 1994 catalogue rounds these to 109/320/419 mm. Shared Service Source reverses width and depth, an unresolved documentation error. Shared maker service table gives 7.7 kg without CD-ROM and 8.6 kg with CD-ROM; weight varies with installed devices	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, according to Service Source. 4.5 V alkaline clock 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	System 7.1.2 with the dedicated System Enabler; Japanese versions use KanjiTalk 7.1.2 and include an ADB Mouse II, with keyboard sold separately. Education and regional monitor/software bundles vary. Announced July 1994, with 2 August shipping planned in contemporary TidBITS; October 1994 maker buying catalogue lists the LC 630, so release uses supported year precision. Exact first retail delivery remains unconfirmed	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
