CPU cores	1	1
Memory
Memory	4 MB	8 MB (better)
Storage
Storage	40 MB to 160 MB	500 MB (better)
CPU
CPU	16 MHz Motorola 68030 with 16-bit data bus, integrated PMMU and 0.5K L1 cache; optional 68882 maths coprocessor, no supplied FPU, L2 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	4 MB onboard, expandable to 10 MB using two paired 30-pin SIMMs, 100 ns minimum; 1, 2 or 4 MB modules. With two 4 MB SIMMs the lower 2 MB onboard cannot be addressed. 1 MB ROM	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	Original Apple Facts and Apple Direct describe 4 MB memory with 40, 80 or 160 MB internal SCSI disks, varying by country; original US ordering sheet explicitly identifies 4 MB/80 MB M1602LL/A. 1.44 MB removable SuperDrive floppy; optional external CD-ROM. Original capacity units retained	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
Expansion slots
Expansion slots	One LC-compatible 96-pin processor-direct slot and optional maths-coprocessor socket; slide-out logic board provides access to memory, VRAM and expansion	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

The exact service manual calls the viewable image 11.5 inches and gives a nominal 240 × 180 mm active raster; these maker descriptions are retained separately
Display features
Display features	256K VRAM supplies 256 colours; optional additional 256K VRAM enables 32,768 colours. Apple IIe card provides 560 × 384 mode at the same 60.15 Hz; this optional-card mode is not native Macintosh resolution	640 × 480 at 66.67 Hz in the exact timing table (66.7 Hz rounded elsewhere in the same manual); 16-bit colour

Size and weight detail
Size and weight detail	Main dimensions and 10.2 kg weight use original Apple Facts metric figures. Original technical library gives 22.5–23.2 lb (10.2–10.5 kg) depending on configuration and slightly different rounded centimetre dimensions	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	Maximum 100 W, automatic 90–240 V AC, 47–63 Hz, 0.83 A; 3.6 V lithium clock battery. Keyboard power control and display power-saving mode	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	Original system software 7.1 and System Enabler 401. Maker announcement 10 February 1993 is not treated as exact first sale; February sale month uses Wikipedia's historical sold-period account, with original March Apple Direct describing an available US configuration. Colour Classic is the regional spelling; no separate Performa 250 or Color Classic II generation added here	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
