CPUMacintosh side uses a 66 MHz PowerPC 601 with integrated FPU and PMMU, 32 KB L1 cache, 256 KB L2 cache and a 64-bit data path at 33 MHz. The separate Intel 80486DX2-66 on the DOS Compatibility Card runs at 66 MHz with a 33 MHz bus and 8 KB internal cache; it runs PC applications independently, rather than adding a second PowerPC core. The main processor comparison describes the Macintosh processor only.75 MHz PowerPC 603 with integrated floating-point unit, 16 KB on-chip cache and 256 KB level-two cache. Apple’s shared developer note explicitly identifies the 5200/75 and 6200/75 processor; their different enclosures remain separate models
GPUMacintosh HDI-45 video uses system DRAM. The DOS card has separate 512 KB video RAM and a VGA controller; Sound Blaster-compatible 16-bit stereo playback is mixed with Macintosh and CD audio. PC sound hardware provides output only, while Macintosh audio has input and output.1 MB DRAM frame buffer, independent of system RAM. Supports 640 × 480 at 32,768 colours or 800 × 600 and 832 × 624 at 256 colours, including compatible VGA/SVGA displays; no built-in screen
Memory type8 MB on the Macintosh logic board and two 72-pin SIMM slots installed in pairs; maximum supported Macintosh RAM 72 MB. The DOS card can share selected Macintosh memory or use its own single 72-pin SIMM up to 32 MB; PC-local memory is not additional Macintosh RAM. AppleFacts also lists 8 MB system memory, but the shown 16 MB/500 MB factory configuration is explicitly ordered as M3972LL/A in Apple's TIL 16756.Two 72-pin non-composite DRAM SIMM sockets; 80 ns or faster memory and 64 MB maximum. October 1995 worldwide catalogue starts with one 8 MB SIMM; Japanese original configuration has 16 MB. Shared developer note documents 4 MB ROM on a DIMM with a 64-bit ROM bus
Storage typeM3972LL/A has a 500 MB internal hard drive, plus built-in 1.44 MB Apple SuperDrive floppy; optional double-speed CD-ROM reads Macintosh and DOS discs. Exact current support gives a broader 350–500 MB range; the initial January newsletter anticipated 16 MB/350 MB before final availability, so that prospective configuration is not added. DOS drive files reside on the Macintosh hard drive.500 MB internal IDE disk, Apple SuperDrive floppy and quadruple-speed internal CD-ROM. Exact Japanese 16 MB/500 MB configuration names AppleCD 600i; worldwide catalogue confirms 8 MB/500 MB pairing. Configurations vary by region; no larger disk/RAM combinations inferred
Expansion slotsThe sole processor-direct expansion position is occupied by the DOS Compatibility Card and its adapter; AV and NuBus expansion cannot coexist in that position. The PC processor card has a local-memory SIMM socket and sound expansion card.LC III-compatible processor-direct expansion slot, communications slot for optional Ethernet or modem, video-input slot and TV-tuner bay. Optional Apple Video System, Apple TV/Video System and Apple Presentation System are separate hardware

PortsEthernet2 × headphone jack
Front ports–Headphone socket, push-button sound controls and infrared receiver for optional television/video remote control
External displaysUp to 2–
Back portsADB, HDI-45 Macintosh display output, DB-25 external SCSI, two GeoPort serial ports, AAUI Ethernet, microphone input and speaker output. The DOS card's 26-pin connection uses a monitor adapter cable with display and PC joystick connectors. Macintosh serial and printer interfaces can emulate PC connections, with compatibility limits in the developer guide.One ADB port, two RS-232/RS-422 serial ports, monitor connector, DB-25 SCSI for up to five external devices, mono sound input and stereo sound output. Optional internal modem occupies one serial channel. Shared developer note specifies 9-pin mini-DIN serial sockets accepting 8-pin or 9-pin plugs
External displaysOne shared display or two separate simultaneous Macintosh and PC displays; only one environment receives keyboard and mouse input at a time. Macintosh video supports 512 × 384 and 640 × 480 at 16-bit colour, or 832 × 624 at 8-bit. DOS card supports VGA/SVGA displays; the developer note lists shared VGA 640 × 480 and SVGA 800 × 600 monitors. Depth and supported modes depend on environment and driver.External Apple multiscan and compatible VGA/SVGA displays, with suitable cables where needed. Japanese specifications support displays up to 20 inches but limit monitors resting on the case to 15 inches; the worldwide catalogue’s 15-inch wording is not a maximum supported resolution
Speakers–Built-in speaker; 8-bit stereo sound output, mono input and 16-bit stereo CD playback. Front and rear headphone outputs cannot be used simultaneously
Microphones–Optional external Apple PlainTalk microphone; no built-in microphone in this desktop enclosure
Keyboard and mouseApple's DOS-card specification lists the compatibility card, MS-DOS 6.22 manual and disks, Windows 3.1, Macintosh PC Exchange User's Guide and monitor cable. Gallery monitor, keyboard and mouse illustrate the original maker setup and do not establish a universal factory bundle.Japanese configuration includes ADB Mouse II, power cable, KanjiTalk 7.5 CD-ROM, manuals and service warranty; keyboard and monitor sold separately.

Size and weight detailOriginal AppleFacts gives 86 × 414 × 396 mm (height × width × depth), used here. Exact support gives 3.4 × 16.3 × 15.6 inches and 14 lb; shared service manual gives 85 × 415 × 399 mm and 6.4 kg depending on installed devices. AppleFacts prints inconsistent 16.2 lb and 3.3 kg; headline weight omitted rather than resolving that conflict by guessing.Exact original Japanese metric specifications: 109.5 mm high, 320 mm wide, 419.5 mm deep, 8.6 kg. October 1995 catalogue rounds height/depth to 109/419 mm and says mass varies with installed devices
Power supplyExact support lists 210 W maximum and automatically configured 100–240 V AC, 50–60 Hz. Shared-family Service Source separately gives 132 W maximum continuous AC input, 201 W peak input excluding monitor power, and 86 W continuous DC output; these ratings retain their different conditions.Original Japanese specifications: automatically configured 100–240 V AC, 50–60 Hz single phase
Power use–Japanese original model: 55 W maximum, excluding monitor consumption. English support archive lists 150 W alongside conflicting modern ports, so that figure is not applied to the original configuration
In the boxOriginal System 7.5 with PowerPC Enabler 1.1.1, MS-DOS 6.22 and Windows 3.1. Apple support records introduction on 3 January 1995; January Apple Directions only promises first-quarter shipments. April 1995 AppleFacts lists the current product and the contemporary June TidBITS review describes a purchased unit, establishing sale in 1995 without proving the first-sale month. Apple explicitly calls the earlier Quadra 610 DOS Compatible its predecessor.Japanese model uses KanjiTalk 7.5; developer note documents the original Power Macintosh hardware. Macworld July 1995 reports Europe had begun shipping the exact 6200/75 and names 28 April as the introduction date, distinguishing the differently bundled Performa 6200CD. Exact actual first retail day/month remains unconfirmed; released uses supported 1995 precision. English support112094 includes unsupported FireWire, AirPort and 10/100 Ethernet claims, excluded in favour of original Japanese specifications, catalogue and developer note
