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 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
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	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
Storage type

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 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
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.

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	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

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 7.1.2 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
