Processor
Processor	Motorola 68LC040 33 MHz (Macintosh LC 575)	Motorola 68040 25 MHz (Macintosh Centris 650)
CPU cores
CPU cores	1	1
Memory
Memory	4 MB or 8 MB	8 MB
Storage
Storage	250 MB (better)	160 MB to 230 MB
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	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	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	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	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 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	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	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	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	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

Back ports
Back ports	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	Two ADB, two RS-232/RS-422 serial mini-DIN-8, DB-25 SCSI, DB-15 video, mono sound input and stereo-capable sound output. 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	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	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
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	Built-in mono speaker; stereo eight-bit sound chip supports external stereo headphones/equipment. Eight-bit monophonic sound input sampled at 11 or 22 kHz

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	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	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 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
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 with System Enabler 040 v1.1 per archived maker specifications. Apple introduction is21October1993, not adopted as first-sale day. Fall1993 maker catalogue offers ordering and a promotion through31December1993, supporting sold during1993; exact first-delivery month remains unconfirmed
