Storage
Storage	–	512 MB to 1 GB
CPU
CPU	Motorola MC68000, nominally 8 MHz with the exact 7.8336 MHz clock frequency published in the original owner guide and technical library; 32-bit internal architecture and 16-bit external data path. No PMMU, FPU, CPU cache or second processor.	75 MHz PowerPC 603 with integrated floating-point unit, 16 KB L1 cache, 256 KB L2 cache and 64-bit data path at 37.5 MHz
GPU
GPU	–	Integrated 1 MB DRAM video; 640 × 480 at 16-bit colour or 832 × 624 at 8-bit colour
Memory type
Memory type	Fixed 512 KB RAM and 128 KB ROM; no RAM slots or built-in memory expansion. The enhanced model has the larger ROM and double-sided floppy drive, without the Macintosh Plus’s expandable memory or SCSI connector.	Two 72-pin SIMM slots; 8 MB standard and 64 MB maximum with 80 ns memory
Storage type
Storage type	One internal 800 KB double-sided 3.5-inch floppy drive, with optional external 400 KB or 800 KB drive. No fixed internal storage or internal CD-ROM. Apple Hard Disk 20 is an optional external device attached through the disk interface, not an internal or SCSI drive.	Apple lists 500 MB and 1 GB internal IDE hard-drive options, a 1.44 MB floppy drive and 2× or 4× CD-ROM drive options
Expansion slots
Expansion slots	None; no standard internal memory expansion. A separately included programmer’s switch can be fitted for reset and interrupt functions by application developers.	Macintosh LC processor-direct slot, communications slot, TV-tuner bay and video input/output slot

Panel
Panel	CRT	CRT
Display type
Display type	Built-in 9-inch monochrome bit-mapped CRT, 512 × 342 pixels. Original owner guide and technical-library sheet agree; the current Apple table’s generic 512 × 384 entry is expressly corrected by its own screen-size note. Native refresh rate unpublished in these exact sources.	Built-in 15-inch multiscan colour CRT with tilt and swivel; it has selectable pixel modes rather than a fixed native LCD resolution
Display features
Display features	–	Maximum listed pixel mode 832 × 624 at 8-bit colour; the developer note also lists 640 × 480 at 16-bit colour

Ports
Ports	Headphone jack	Headphone jack
Back ports
Back ports	DB-9 mouse connector, RJ11 synchronous serial keyboard bus, two DB-9 RS-232/RS-422 serial connectors, external floppy DB-19 and sound output for amplifier/headphones. No ADB, USB, FireWire, Ethernet, external video or SCSI connector. Current Apple support warns that the serial ports do not support handshaking or synchronous modems.	Apple Desktop Bus, external DB-25 SCSI, two serial connectors, microphone input and stereo sound output; optional DB-15 video-mirroring port
Speakers
Speakers	Built-in sound system; original maker guide specifies four-voice sound with 8-bit digital-to-analogue conversion at 22 kHz. No built-in microphone.	Built-in stereo speakers and microphone
Keyboard and mouse
Keyboard and mouse	Original guide describes a separate 58-key detachable keyboard, mouse, System Tools disk, Guided Tour disk and audio cassette, plus a programmer’s switch. Maker cover shows an extended keyboard with numeric keypad; gallery photos can include optional external drives, keyboards, printers and other separately supplied equipment. These are labelled rather than treated as standard computer hardware.	–

Size and weight detail
Size and weight detail	Main figures use later exact Apple technical-library metric values: 346 mm high × 246 mm wide × 276 mm deep and 7.5 kg main-unit weight. Original 1986 owner guide instead gives 344 mm height; current support retains 13.6H × 9.6W × 10.9D inches. These small maker rounding differences are retained explicitly. Keyboard and mouse excluded; original guide separately lists 1.2 kg keyboard and 0.2 kg mouse.	Apple lists 17.5 × 15.1 × 16 inches and 47 lb for the 5200 form factor
Power supply
Power supply	Exact technical-library sheet specifies 105–125 V AC, 50–60 Hz and maximum 60 W for this documented voltage version; no universal-voltage claim. User-replaceable 4.5 V Eveready No. 523 or equivalent clock battery.	Maximum 125 W; 110–240 V AC at 50–60 Hz; 4.5 V alkaline clock battery
In the box
In the box	Exact original guide is titled Macintosh 512K enhanced, the long name of Macintosh 512Ke. Current maker support lists introduction 14 April 1986 and discontinuation 1 September 1987; a distinct first retail-sale date has not been established, so released is omitted. The guide names Macintosh 512K enhanced System Tools; the current support table’s retrospective original-system-software entry is not adopted as a verified launch disk version. Photographs are original maker owner-guide images of this exact model, with scan colour casts and period screen contents retained.	Original System Software 7.5.1. Apple lists 1 May 1995 as introduction; a separate first-sale date was not established.
