Apple Service Source: Apple gives 4 MB of DRAM on board expandable to 8 MB in one 72-pin SIMM - there is no 1 MB SIMM and no 5 MB configuration (5 MB is the Performa 575/577 figure); weight is 41.5 lb (18.9 kg), not the Performa 550's 40.5 lb; sound is monaural IN and stereo out; VRAM is 512K and cannot be expanded, so the 256-colour ceiling is not a missing SIMM; added Apple's 120 W supply, 160 MB SCSI drive, 13-inch viewable / 0.26 mm Trinitron figures, two ADB ports, the 3.0 V lithium batt...

! Item !! Apple's figure
|-
| Processor || Motorola 68030 at 32 MHz with built-in memory management unit; socket for an optional math coprocessor
|-
| RAM || '''4 MB of dynamic RAM on board'''; expandable to '''8 MB''' in one 72-pin DRAM SIMM connector, 100 ns or faster. There is no 1 MB SIMM in this machine and no 5 MB configuration
|-
| ROM || 1 MB, expandable to 2 MB
|-
| PRAM || 256 bytes of clock/calendar/parameter memory with a long-life lithium battery
|-
| VRAM || '''512K on board, giving up to 256 colours (8-bit). Not expandable'''
|-
| Storage || 3.5-inch internal '''160 MB SCSI''' hard drive; internal AppleCD 300i double-speed CD-ROM; internal 1.4 MB Apple SuperDrive
|-
| Display || 14-inch diagonal with a '''13-inch viewable screen'''; Trinitron CRT with high-contrast glass; '''0.26 mm aperture grille pitch'''; 640 × 480 at 70 dpi
|-
| Sound || Sound-output port capable of delivering '''stereo'''; sound-input port for '''monaural''' input; front headphone jack capable of stereo; records and plays back at 11 or 22 kHz; two speakers with enhanced stereo sound
|-
| Infrared || Receiver for the remote control
|-
| ADB || '''Two''' ADB ports, mini DIN-4; maximum three devices recommended; 500 mA total (mouse 10 mA, keyboard 25 mA)
|-
| SCSI || One DB-25 parallel port, up to '''six''' external devices
|-
| Electrical || 100–240 VAC universal supply; 47–63 Hz single phase; '''120 W maximum'''
|-
| Case || Height 17.9 in. (45.5 cm), width 13.5 in. (34.4 cm), depth 16.5 in. (42.0 cm)
|-
| Weight || '''41.5 lb. (18.9 kg)''' &mdash; one pound heavier than the Performa 550 and 560 in the same shell, which are 40.5 lb.
|-
| PRAM battery || Verify on the '''10 V DC''' scale; '''replace below 3.0 V'''. A lithium cell &mdash; neutralise leakage with '''sodium bicarbonate''', never vinegar

The Adjustments chapter is Light Meter Setup, Geometry, Geometric Distortion, Convergence, Video and Yoke:
'''there is no rail-voltage adjustment or tolerance table for this machine.'''<ref name="sstv" />
'''A thin grey horizontal line across the lower third of a lit screen is not a fault.''' Apple's own
symptom chart says it "is inherent in the design of Trinitron monitors. Do not replace modules." It is the
damper wire.<ref name="sstv" />
