CPU
CPU	8 MHz 68000; maker lists no PMMU, FPU, cache or second processor	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
GPU
GPU	–	Built-in video uses 1 MB DRAM soldered to the logic board, displaying 32,768 colours at 640 × 480
Memory type
Memory type	Fixed 128 KB RAM and 64 KB ROM, Apple's original SE/30 owner manual Macintosh product-line appendix and contemporaneous reviews. Retained Apple support sheet incorrectly labels RAM 0.125 MB; no built-in expansion, with third-party upgrades described separately	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
Storage type
Storage type	Built-in 400 KB removable floppy drive, manually loaded and automatically ejected; no internal hard drive or hard-drive interface. Floppy capacity remains removable-media detail, not main internal storage	500 MB internal IDE hard disk in the catalogue configuration, plus manual-inject Apple SuperDrive floppy. 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

Size and weight detail
Size and weight detail	Maker 16.5 lb and 13.6 in height × 9.6 in width × 10.9 in depth; original units retained	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
Power supply
Power supply	Maker maximum 60 W, 105–125 V, 50–60 Hz, 0.5 A; 4.5 V alkaline	Automatically configured 100–240 V AC mains; service supply operating range 90–264 V rms, 50–60 Hz ±3 Hz
Power use
Power use	–	Service Source: 120 W maximum for all line and load conditions. Current support article describes a PowerPC-upgraded configuration and lists 60 W, so that figure is not transferred to the original model
In the box
In the box	Separate keyboard and mouse; initial MacWrite/MacPaint bundle described by LA Times. Apple introduction 24 January 1984; January retail month supported by actual 29 January LA Times review, not inferred exact first-sale day. BYTE identifies Motorola 68000; support sheet omits supplier	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
