CPU
CPU	Original Motorola 68LC040 at 33 MHz, without an integrated floating-point unit. Apple catalogue gives 66/33 MHz internal/bus clock; optional PowerPC upgrade is excluded from this configuration. Shared Service Source describes it as an updated LC 575	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 uses 1 MB DRAM soldered to the logic board, displaying 32,768 colours at 640 × 480	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 standard in the maker catalogue: 4 MB soldered plus one 4 MB SIMM, with a second socket free. Two 72-pin 80 ns SIMM sockets, expandable to 52 MB; the single-bank socket accepts only 1, 4 or 16 MB modules. 1 MB ROM in original service specifications	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	500 MB internal IDE hard disk in the catalogue configuration, plus manual-inject Apple SuperDrive floppy. Double-speed tray-loading internal CD-ROM is optional or included in some regional configurations; the separately marketed Performa 580CD has its own software and hardware bundle	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	One 114-pin LC processor-direct slot, one communications slot for optional Ethernet or fax modem, one video-input slot for optional capture hardware and an internal connector for optional external video	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

Size and weight detail
Size and weight detail	Apple catalogue: 455 × 343 × 419 mm (height × width × depth), 18.3 kg, varying with installed devices. Service Source rounds the same 17.9 × 13.5 × 16.5 inch case to 455 × 344 × 420 mm and 18.4 kg; headline follows the catalogue’s published metric values	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	Automatically configured 100–240 V AC mains; service supply operating range 90–264 V rms, 50–60 Hz ±3 Hz	100–240 V AC, 50–60 Hz; 45 W maximum excluding monitor, according to Service Source. 4.5 V alkaline clock battery
Power use
Power use	Service Source: 120 W maximum for all line and load conditions. Current support article describes a PowerPC-upgraded configuration and lists 60 W, so that figure is not transferred to the original model	–
In the box
In the box	Original 68LC040 model is offered in Apple’s April and October 1995 catalogues; the latter identifies US education-only sales and varying worldwide configurations. Current Apple support article describes an installed PowerPC 601 upgrade card. It records introduction on 3 April 1995, while contemporary Macworld says education shipping was planned for that day; exact actual first retail delivery is unconfirmed, so release retains supported year precision	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
