CPU
CPU	180 MHz PowerPC 603e with integrated floating-point unit, 32 KB L1 cache and a 64-bit 40 MHz bus. The 256 KB Apple High Performance Module L2 cache is optional, unlike the standard cache of the 6400/200. The shared Service Source calls the processor 603ev; the exact specification page and original brochure use 603e.	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	1 MB built-in video DRAM, not expandable; 640 × 480 and 800 × 600 at 16-bit colour, 832 × 624 and 1024 × 768 at 8-bit colour. A separate PCI graphics card is needed for additional capabilities.	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 soldered to the logic board and an 8 MB DIMM supplied; two 168-pin 64-bit fast-page-mode DIMM sockets support up to 136 MB total, with 70 ns or faster memory.	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	1.6 GB internal IDE hard drive, 1.44 MB SuperDrive floppy drive and tray-loading 8× CD-ROM. The shared service manual lists a 1.2 GB drive and AppleCD 600i for generic 6400 configurations; the exact 180 MHz support page and ordering brochure agree on 1.6 GB and 8×.	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	Two PCI 2.0 slots for 6.88-inch cards with Mac drivers; Communications Slot II occupied by the supplied modem, plus positions for optional video input and TV/FM tuner cards. One pre-cabled 5.25-inch internal SCSI bay. Optional Avid Cinema requires the Apple Video System and occupies one PCI slot; it is not supplied with the standard 180 MHz configuration.	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	DB-15 monitor output, ADB, DB-25 external SCSI, two GeoPort-compatible serial ports, 3.5 mm sound input compatible with PlainTalk microphones and line-level 3.5 mm speaker output. The supplied modem provides 28.8 Kbit/s data and 14.4 Kbit/s fax; replacing it with an Ethernet card provides wired networking. Optional video input handles composite and S-video NTSC, PAL or SECAM.	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	–	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	Built-in full-range monophonic speaker switches to subwoofer operation when external speakers are connected. 16-bit stereo input/output at 11.025, 22.05 or 44.1 kHz; SRS surround processing applies to rear sound output, not the front headphone jack.	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	Keyboard, mouse, cables and bundled applications listed for US order M5167LL/A; display, TV/FM tuner, Apple Video System, Avid Cinema and PC Compatibility Card are optional. Gallery image includes an optional monitor.	–

Size and weight detail
Size and weight detail	Original brochure lists 40.6 × 19.8 × 42.8 cm (height × width × depth), matching the service manual. Weight is 20.18 kg without the monitor and varies with installed devices; the service manual explicitly excludes the CD-ROM drive. The technical booklet transposes depth and height labels.	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	Exact specification page and ordering brochure list 220 W maximum, 100–125 or 200–240 V AC at 47–63 Hz. The shared service manual agrees on 220 W maximum continuous but gives wider voltage bands; the original technical booklet instead states 140 W input and 98 W DC output. These conflicting ratings are retained rather than treated as measured consumption.	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	Original System Software 7.5.3 with System Enabler 410 v1.1. Apple lists 5 August 1996 as introduction; the original 1996 ordering brochure and contemporary MacUser review establish sale in 1996, but a distinct first-sale month remains unresolved.	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
