Macintosh Classic compared with Macintosh Performa 5400/160

	AppleMacintosh Classic	AppleMacintosh Performa 5400/160
Overview
Released
Released	October 1990	1996
Performance
Processor
Processor	68000 8 MHz (Macintosh Classic)	PowerPC 603e (160 MHz, Macintosh Performa 5400/160)
CPU cores
CPU cores	1	1
Memory
Memory	1 MB or 2 MB	16 MB (better)
Storage
Storage	40 MB	1.6 GB (better)
CPU
CPU	8 MHz 68000 with 16-bit data path; no PMMU, FPU, cache or second processor	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	–	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	1 MB onboard, expandable to 4 MB using a memory expansion card and two paired 30-pin SIMMs; current support sheet specifies 120 ns modules and 256K or 1 MB sizes, excluding two-chip 1 MB modules. Older Apple technical library lists 150 ns and 32-pin; current support sheet controls. 512K ROM	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	1.44 MB removable floppy; optional 40 MB internal SCSI hard disk. Original capacity units retained. Apple Australia October 1991 brochure explicitly offers 2 MB floppy-only and 2 MB/40 MB configurations; original 1 MB floppy-only base is identified by contemporary model descriptions	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	No processor expansion slot; memory expansion card required beyond 1 MB	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 9-inch monochrome CRT, 512 × 342 pixels; original Apple technical library and Australia brochure corroborate the explicit support-sheet correction to its generic 512 × 384 table	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.
Connections
Ports
Ports	Headphone jack	2 × headphone jack
Front ports
Front ports	–	Headphone output and volume controls; built-in infrared remote capability. Remote-control inclusion varies with regional configuration.
Back ports
Back ports	One ADB, DB-19 external floppy, DB-25 SCSI, printer and modem serial ports, and sound output; no built-in Ethernet or external video port	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 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	Four-voice 8-bit sound at 22 kHz; built-in speaker and headphone output described in Apple technical library	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	–	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	Apple Keyboard II and ADB mouse, according to original Apple technical library	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 technical library gives 33.6 cm height × 24.6 cm width × 28.5 cm depth; current support sheet gives 16 lb. Internal drive affects weight, so no single converted weight supplied	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	Current support sheet specifies maximum 76 W, 120 V, 47–63 Hz and 0.63 A; 3.6 V lithium clock battery. Older Apple technical library states 100 W, retained as a source conflict	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.
In the box
In the box	Original system software 6.0.7. Apple introduction 15 October 1990 is not treated as exact first sale; October 1990 sale month comes from Wikipedia's historical model account, cross-checked against contemporary November and February retail coverage	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.
