Storage	1.2 GB (better)	160 MB to 230 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	25 MHz Motorola MC68040 with integrated FPU and memory management unit, 32-bit data bus and 8 KB cache on the datasheet/catalogue configurations listed here. Apple developer note confirms an entry-level MC68LC040 version without FPU, plus socketed processors; its exact RAM/storage pairing has not been established in maker ordering tables and is not invented here. DOS Compatible hardware and later PowerPC upgrades are separate options
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	512 KB VRAM standard, upgradable to 1 MB. At 640 × 480, 512 KB gives 256 colours and 1 MB gives 32,000 colours; at 1152 × 870, 16 shades with 512 KB and 256 with 1 MB. The 8/230CD configuration includes 1 MB VRAM
Memory type
Memory type	Two 72-pin SIMM slots; 16 MB minimum and 64 MB maximum with 80 ns memory	4 MB DRAM on the logic board plus two 72-pin SIMM slots; 8 MB supplied in the maker catalogue configurations. Up to 68 MB total; 80 ns or faster SIMMs can be installed individually. 1 MB ROM
Storage type
Storage type	1.2 GB internal IDE hard drive, 1.44 MB floppy drive and 4× CD-ROM drive	1.44 MB Apple SuperDrive with enlarged manual-insertion slot, replacing the Centris automatic-injection design. Maker ordering offers 8/160 with hard disk and no CD-ROM, or 8/230CD with 230 MB SCSI hard disk and AppleCD 300i double-speed drive
Expansion slots
Expansion slots	Macintosh LC processor-direct slot, communications slot, TV-tuner bay and video input/output slot	One internal slot accepts either a processor-direct card or a seven-inch NuBus card with the required adapter. Internal bay for optional 5.25-inch half-height storage device; not a full-length NuBus chassis

AAUI-15 Ethernet included on the datasheet/catalogue versions; optional across the wider family and absent from the entry-level version. No USB or external floppy connector
External displays
External displays	–	Maker lists built-in support for Apple displays and compatible RGB/VGA/SVGA displays. Separate monitor and keyboard; catalogue setup image shows Macintosh Color Display and Apple Extended Keyboard II as separately ordered options

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 datasheet metric dimensions retained: H8.5/W41.5/D39.7 cm; 6.4 kg varies with internal devices. Shared Service Source incorrectly prints depth4.2in/107mm; exact datasheet and archived support agree15.6in depth
Power supply
Power supply	Maximum 55 W; 110–240 V AC at 50–60 Hz; 4.5 V alkaline clock battery	100–240 V AC with automatic configuration; exact datasheet gives 50–60 Hz and 210 W maximum excluding monitor. Shared Service Source lists 112 W excluding monitor; preserve the source disagreement rather than treat either as measured running consumption. 3.6 V lithium clock battery
