Storage
Storage	250 MB	250 MB to 500 MB (better)
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	66 MHz PowerPC 601 with integrated memory management and floating-point unit, 32 KB L1 cache and 64-bit data path at 33 MHz
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 HDI-45 video uses system DRAM; separate DB-15 video has 1 MB VRAM standard and supports 2 MB for up to 24-bit colour 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	8 MB on the logic board plus four 72-pin SIMM slots installed in pairs; Apple supports 8–136 MB total
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	Internal 1.44 MB floppy drive, 250 or 500 MB SCSI hard drive and optional 2× CD-ROM 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	Three NuBus slots; processor-direct slot filled by the video card

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	Apple Desktop Bus, DB-15 and HDI-45 video, DB-25 SCSI, two GeoPort serial connections, AAUI-15 Ethernet, microphone input and speaker output
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	DB-15 video supports up to 1152 × 870 pixels; available colour depth depends on VRAM
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	–

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	Apple's 6 × 13 × 16.5 inch and 25 lb reference dimensions; metric fields are rounded conversions
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	Maximum 230 W; 100–240 V AC, 50–60 Hz; 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	Original System Software 7.1.2 with PowerPC Enabler. Apple lists 14 March 1994 as introduction; a separate maker first-sale date was not established.
