Memory
Memory	8 MB	16 MB (better)
Storage

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	160 MHz PowerPC 603e with integrated floating-point and memory management units, 32 KB L1 cache and 64-bit memory bus. Optional High Performance Module adds 256 KB L2 cache; it is not standard. Current Apple support gives a 40 MHz data path clock.
GPU
GPU	Built-in video uses 1 MB DRAM soldered to the logic board, displaying 32,768 colours at 640 × 480	1 MB DRAM framebuffer independent of system RAM. Shared Service Source explicitly supports 640 × 480 at 60 or 67 Hz and 800 × 600 at 60 or 72 Hz with 16-bit colour; 832 × 624 at 75 Hz uses 8-bit colour and does not support video input. Current support additionally lists 1024 × 768, but the exact technical specification and shared service manual restrict the built-in CRT to 832 × 624; the higher database row is not adopted as the built-in display resolution.
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	16 MB standard, comprising 8 MB soldered RAM and one 8 MB DIMM. Two 168-pin 64-bit DIMM slots allow expansion to 136 MB with two 64 MB modules. Use 70 ns or faster fast-paged-mode DIMMs with 1K or 2K refresh. Modules can be installed individually. 4 MB ROM.
Storage type
Storage type	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	Exact 160 MHz maker specification, ordering description and Service Source configuration agree on a 1.6 GB IDE hard drive, Apple SuperDrive 1.44 MB floppy drive and internal 8× AppleCD CD-ROM drive. November 1996 Apple Facts gives a 1.2 GB drive for the broader 160/180 Performa family; that unqualified family figure is not transferred to the exact configuration.
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	One PCI slot for a 6.88-inch, 15 W card; communications slot occupied by the supplied modem; optional video-input card and TV/FM tuner bay. Optional Apple External Video Connector enables mirroring; optional Apple Presentation System provides NTSC/PAL output. NuBus cards cannot be used in the PCI slot.

Display type
Display type	Built-in 14-inch diagonal shadow-mask colour CRT, 0.28 mm dot pitch. 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	15-inch nominal RGB CRT with 12.8-inch viewable diagonal and 0.28 mm dot pitch. Noninterlaced flat square tube. Base tilts from −5° to +15° and swivels 360°. Resolution can be changed without restarting.

Front ports
Front ports	Stereo headphone socket; front brightness and contrast controls	Headphone output and volume controls; built-in infrared remote capability. Remote-control inclusion varies with regional configuration.
Back ports
Back ports	One ADB port; one DB-25 SCSI port supporting six external devices; two RS-232/RS-422 serial ports, with 9-pin mini-DIN modem and 8-pin mini-DIN printer connectors; mono sound input and stereo sound output	One ADB port; two GeoPort-compatible RS-232/422 serial ports, including LocalTalk support; DB-25 SCSI; stereo sound input and rear stereo sound output. Optional DB-15 external-video connector, not a standard fitted port. Built-in 28.8 Kbit/s V.34 data/fax/voice modem supports MNP4, V.42, MNP5 and V.42bis; optional Ethernet replaces the communications-slot modem. No USB or FireWire.
External displays
External displays	Optional external video connector supports mirroring on compatible 640 × 480 and 800 × 600 monitors, as listed in the shared service manual; no external video socket as standard	Optional external-video connector provides mirroring of the built-in screen. Connector kit, suitable cable and external display required; external video does not establish an independent second desktop.
Speakers
Speakers	Two integrated speakers; 8-bit stereo playback and mono recording at 11 or 22 kHz. Optional CD-ROM supports audio-CD playback	Built-in stereo speakers and 16-bit stereo sound with SRS 3D surround enhancement. Shared service manual identifies separate front and rear stereo output jacks. Headline jack count excludes the sound-input port.
Microphones
Microphones	Integrated microphone for monaural sound input	Built-in microphone and stereo sound-input port; the input also supports an external Apple PlainTalk microphone. Shared manual explicitly excludes the earlier Apple Omni microphone from this input.
Keyboard and mouse
Keyboard and mouse	Supports Apple Desktop Bus keyboards and the ADB Mouse II. Maker photograph shows a keyboard and mouse; regional education bundles vary	Exact maker ordering description includes keyboard, mouse and necessary cables; the CRT, microphone, speakers, modem, CD-ROM, floppy drive and hard drive are built into the computer. Optional TV/FM and video hardware varies by regional bundle.

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	Exact maker specification gives 445 × 383 × 406 mm (height × width × depth) and 21 kg. Its 17.5 × 15.1 × 16 inches and 47 lb are retained as maker-rounded equivalents. Apple Facts notes weight varies with installed internal devices; no shipping-package mass is used.
Power supply
Power supply	Automatically configured 100–240 V AC mains; service supply operating range 90–264 V rms, 50–60 Hz ±3 Hz	220 W maximum continuous input, nominal 110–240 V AC at 50–60 Hz, single phase. Low-power sleep mode supported. Current maker table gives a 4.5 V alkaline clock battery; maximum input is not normal operating consumption.
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 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 7.5.3 with System Enabler 410, Apple Guide, QuickTime, Macintosh PC Exchange and QuickDraw 3D. Exact October 1996 ordering description and November Apple Facts dealer catalogue establish retail offering in 1996; precise first-sale month or day remains unestablished. Apple's recorded introduction is 5 August 1996. Service Source identifies sale in Japan, Australia and Europe; not sold in the US. This 160 MHz configuration is distinct from the existing Power Macintosh 5400/120, 5400/180 and 5400/200. No unsupported official predecessor link assigned.
