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.66 MHz PowerPC 601 with integrated floating-point unit, 32 KB L1 cache, standard 256 KB L2 cache and 64-bit data path at 33 MHz; 4 MB ROM
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.AV video card with fixed 2 MB VRAM, plus separate HDI-45 video using system DRAM
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 16756.8 MB soldered to the logic board and two 72-pin noncomposite 80 ns SIMM sockets accepting a matched pair; maximum 72 MB total. English support lists an 8 MB minimum; Japanese 6100/66 bundle includes 16 MB, with the AV card sold separately.
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.English support lists a 350 MB internal SCSI hard drive. Original Apple TIL describes 8 MB/350 MB 6100/66 bundles and states that the AV card upgrades them to the 66AV; Japan offers 16 MB/350 MB with 2× AppleCD 300i Plus and separately sold AV card. Those AV-installed configurations are shown, without implying that the Japanese AV card was bundled. Service Source lists CD-ROM standard in some 66AV configurations and optional in others; 1.44 MB Apple SuperDrive floppy is built in.
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.One processor-direct expansion position occupied by the AV card. A NuBus adapter cannot be used while retaining the AV card.

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.ADB, AAUI-15 Ethernet, HDI-45 and DB-15 video, external DB-25 SCSI, two LocalTalk/GeoPort serial ports, 16-bit stereo audio input and output, and S-video input and output with composite adapters
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.Two simultaneous displays using DRAM and AV-card outputs. AV VRAM supports 24-bit colour at 640 × 480 and 832 × 624, or 16-bit colour at 1024 × 768 and 1152 × 870. Only one monitor or television can be attached to the AV card at a time.
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.Original Apple TIL lists power cord, keyboard cable, mouse and microphone; Japanese standard 6100/66 bundle includes mouse and display adapter with keyboard sold separately. AV-card and regional bundle accessories remain distinct.

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.Shared Service Source gives 85 × 415 × 399 mm and 6.4 kg, varying with installed devices. Japanese 6100/66 page gives 396 mm depth; April 1995 AppleFacts gives 86 × 411 × 396 mm and 6.3 kg. Different maker measurements remain qualified; shared service values retained for this AV record.
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.Automatically configured 100–240 V AC, 50–60 Hz.
