CPU33 MHz Motorola 68030 with integrated PMMU, 32-bit data path at 33 MHz and 0.5K L1 cache; no L2 cache. Optional Motorola 68882 maths coprocessor, not supplied as standard. Exact current Apple specifications override the archived Service Source table, which incorrectly retains a 16-bit bus and 16-bit registers from the original Color Classic.Nominal 16 MHz 68030 with 32-bit data path, integrated PMMU and 68882 FPU; 0.5K L1 cache, no L2 or second processor. Original owner manual specifies 15.6672 MHz exact clock; nominal support-sheet rating retained
Memory type4 MB soldered memory, one 72-pin SIMM slot and 36 MB maximum; minimum 80 ns, supported module capacities 1, 2, 4, 8, 16 and 32 MB. 1 MB ROM. Exact current maker table overrides the shared service manual’s conflicting two 30-pin SIMMs and 10 MB limit.Eight 30-pin SIMM slots in groups of four, 120 ns or faster; support sheet certifies 1–32 MB and 256K, 1 MB or 4 MB modules. Original manual describes 8 MB with then-current modules and future 128 MB expansion; limits depend on installed modules and software. 256K ROM
Storage typeApple’s exact Japanese Performa 275 bundle has 8 MB RAM and a 160 MB SCSI hard drive, retained in configurations. Color Classic II support lists 80–160 MB internal disks but does not establish each factory RAM/disk pairing; no guessed combinations added. Internal 1.44 MB SuperDrive floppy, optional external CD-ROM. Original capacity units retained.Factory choices from original Apple technical procedures are 1 MB RAM with floppy only, 1 MB with 40 MB SCSI disk, or 4 MB with 80 MB SCSI disk; all have an FDHD high-density floppy drive. Original capacity units retained; floppy capacity is removable storage
Expansion slotsOne LC-compatible processor-direct slot; optional Ethernet expansion card and optional 68882 coprocessor. User-removable logic board. No standard Ethernet adapter.One 120-pin 32-bit 030 Direct Slot; optional monitor connection requires a compatible video card

Refresh rate–60.1 Hz
Display typeBuilt-in 10-inch colour CRT tube with 512 × 384 Macintosh resolution. Exact current maker support does not identify a separate viewable diagonal or refresh rate; the archived service manual conflicts over display size, so neither a viewable-area measurement nor refresh rate is inferred.Built-in 9-inch one-bit monochrome CRT, 512 × 342 pixels. Maker's explicit note and owner manual correct generic support table's 512 × 384
Display features256K built-in VRAM supplies 256 colours; optional additional 256K VRAM supports 32,768 colours. The Japanese Performa 275 specification confirms both modes.Original owner manual specifies exact 60.1 Hz refresh
Connections
PortsHeadphone jackHeadphone jack
Back portsTwo ADB ports, DB-25 SCSI, printer and modem serial connections, and audio connections; no external video or floppy connector, USB or FireWire. Ethernet is optional through expansion.Two ADB ports, DB-19 external floppy, DB-25 SCSI, two RS-232/RS-422 serial ports and stereo mini-phone audio output; no built-in Ethernet or external video socket
SpeakersBuilt-in speaker and omnidirectional microphone. Exact Japanese Performa 275 table calls the internal speaker system stereo; the archived service manual describes monophonic audio. This unresolved wording is retained without asserting stereo playback for every regional configuration.Apple Sound Chip supports four-voice wavetable synthesis and stereo sampling; mixed stereo through a monophonic internal speaker, stereo through external sound port
Keyboard and mouseArchived shared Service Source lists a keyboard, ADB Mouse II, ADB and power cables. The exact Japanese Performa 275 bundle includes an Apple Keyboard II and bundled Japanese At Ease, ClarisWorks, HyperCard Lite and Photo CD Sampler software; regional software and keyboards can differ.Choice of Apple Keyboard or Apple Extended Keyboard; ADB mouse, as described in original owner manual

Size and weight detailExact current Apple support publishes 14.5 inches high × 9.9 inches wide × 12.6 inches deep and 22.5 lb weight. The archived shared manual instead provides differently rounded metric dimensions and a 22.5–23.2 lb configuration range; those values are not silently substituted for the exact current figures.Maker 19.5 lb; 13.6 in height × 9.6 in width × 10.9 in depth, retained in original units
Power supplyMaximum 100 W; automatic 90–240 V AC, 47–63 Hz. Apple lists 0.83 A and a 3.6 V lithium clock battery. Keyboard soft-power control.Maximum 75 W, 120–240 V, 48–62 Hz, 0.63 A; 3.6 V lithium clock battery
In the boxOriginal Japanese system software 7.1 with System Enabler 403; Apple lists support through Mac OS 7.6.1. Current maker support gives 21 October 1993 as introduction, which does not establish first retail sale; released omitted. Apple states this system was not sold in the US. Performa 275 is a Japanese consumer bundle of this hardware, not a separate generation. The main image and additional views are original maker service illustrations, not press photographs; exact-model photographic coverage remains unresolved.Original system software 6.0.3. Maker introduction 19 January 1989 is not treated as exact first sale; earliest actual-sale month unresolved in bounded search, released year only
