CPU	33 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.	100 MHz PowerPC 603e with integrated floating-point unit, 32 KB L1 cache, 256 KB L2 cache and 64-bit data path at 40 MHz
GPU
GPU	–	Integrated 1 MB DRAM video supports 640 × 480 at 16-bit colour or 832 × 624 at 8-bit colour through the DB-15 monitor port
Memory type
Memory type	4 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.	Two 72-pin SIMM slots; 16 MB minimum and 64 MB maximum with 80 ns memory
Storage type
Storage type	Apple’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.	1.2 GB internal IDE hard drive, 1.44 MB floppy drive and 4× CD-ROM drive
Expansion slots
Expansion slots	One LC-compatible processor-direct slot; optional Ethernet expansion card and optional 68882 coprocessor. User-removable logic board. No standard Ethernet adapter.	Macintosh LC processor-direct slot, communications slot, TV-tuner bay and video input/output slot

Display type
Display type	Built-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.	–
Display features
Display features	256K built-in VRAM supplies 256 colours; optional additional 256K VRAM supports 32,768 colours. The Japanese Performa 275 specification confirms both modes.	–

Ports	Headphone jack	Headphone jack
Back ports
Back ports	Two 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.	DB-15 monitor output, Apple Desktop Bus, external DB-25 SCSI, two serial connectors, microphone input and stereo sound output
Speakers
Speakers	Built-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.	–
Keyboard and mouse
Keyboard and mouse	Archived 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.	–

Size and weight detail
Size and weight detail	Exact 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.	Apple lists 4.3 × 12.6 × 16.5 inches and 19 lb for the Quadra 630 form factor
Power supply
Power supply	Maximum 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 55 W; 110–240 V AC at 50–60 Hz; 4.5 V alkaline clock battery
In the box
In the box	Original 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 7.5.1. Apple lists 16 October 1995 as introduction; a separate first-sale date was not established.
