These are the specifications of the Power Macintosh 5260 as Apple printed them in its service manual for the machine, Power Macintosh/Performa 5260, 5280 Series. Where Apple's technical-specification pages for the two models give a different figure, both are shown. The Power Macintosh/Performa 5200 and 5300 manual is titled "(not 5260, 5280)", and its figures do not apply to this machine.

Processor and memory

Processor and memory

Item	Service manual	Specification pages
CPU	PowerPC 603e, 100 MHz (5260/100) or 120 MHz (5260/120, 5280)	Same; FPU and PMMU integrated
Bus	64-bit PowerPC bus	64-bit data path, 40 MHz
Level-1 cache	Not stated	32 KB
Level-2 cache	256 KB	256 KB (5260/100); optional (5260/120)
DRAM	16 MB minimum, expandable to 64 MB; 72-pin SIMMs, 80 ns or faster	16 MB to 64 MB; two slots; 4, 8, 16 or 32 MB SIMMs, fitted singly
Frame buffer	1 MB DRAM on the logic board	1 MB DRAM, built in
ROM	4 MB	4 MB

EveryMac gives 8 MB or 16 MB as the standard RAM of the 5260/100, and the service manual's model overview (p. 4) lists a 16 MB minimum as one of the differences of the 5260/120 from the 5260/100.

Disk storage

Disk storage

Item	Service manual
Floppy drive	1.4 MB Apple SuperDrive, manual insert
Hard drive	800 MB, 1.2 GB or 1.6 GB IDE
CD-ROM, 5260/100	AppleCD 600i
CD-ROM, 5260/120 and 5280	AppleCD 1200i

Apple's specification pages give a 4× drive for the 5260/100 and 8× for the 5260/120.

Display

Built-in display

Item	Service manual
Tube	14-inch shadow mask, 12.8-inch viewable image
Dot pitch	0.28 mm
Phosphor	Aluminised P22 (red, green, blue)
White point	9,300 K
Shipping brightness	25 foot-lamberts nominal
Vertical frequency	66.7 Hz
Active raster size	9.5 × 7.3 in (240 × 185 mm) nominal
Video mode	640 × 480 at 16-bit colour
Phosphor CIE coordinates	Red x = 0.643 ± 0.020, y = 0.324 ± 0.020; green x = 0.301 ± 0.020, y = 0.606 ± 0.020; blue x = 0.142 ± 0.015, y = 0.056 ± 0.015

The 240 × 185 mm raster is also the target of Apple's size adjustments, with a tolerance of ± 2 mm (pp. 194–195).

Monitor timing, 640 × 480 at 66.67 Hz

Timing of the built-in display

Item	Horizontal	Vertical
Back porch	96 dots	39 lines
Sync	64 dots	3 lines
Front porch	64 dots	3 lines
Rate	35.000 kHz	66.666 Hz
Dot clock	30.24 MHz (33.06878 ns per dot)

The manual prints this table twice, once headed "at 60 Hz" with the same figures, and prints the line period as "28.5714 ms" where 28.5714 µs is meant (pp. 37–38).

Sound

• 16-bit mono input and 16-bit stereo output; output level nominally 0.5 V RMS into 39 Ω
• Records at 11 kHz or 22 kHz and plays back at 22 kHz
• Built-in microphone; sound-input port for microphone or line level, which accepts a stereo signal and mixes it to mono
• Two stereo output ports (front headphone jack and rear mini jack) and internal stereo speakers; the internal speakers are muted when a plug is inserted into an output jack

Source: pp. 31–32 and 35. Apple's specification pages add an input impedance of 100 kΩ, average line level 100 mV RMS, average microphone level 70 mV RMS and maximum input 1.8 V RMS.

Ports and expansion

• Two RS-232/422 serial ports (mini DIN-8), LocalTalk supported
• One external SCSI port (DB-25), up to seven devices
• One ADB port (mini DIN-4)
• One 60-pin video-in slot for real-time video display, capture and overlay
• One 10-pin port for a TV tuner card
• One 112-pin communications slot (68040-bus configuration) for a modem or Ethernet card
• One 96/114-pin LC-compatible processor-direct slot
• External video: DB-15 mirror output through the optional video connector kit, for presentation only
• Controls: soft power from the keyboard, front-panel buttons for volume and brightness, optional infrared remote

Electrical

Electrical

Item	Service manual	Specification pages
Line voltage	100–240 V AC	110–240 V
Frequency	47–63 Hz	50–60 Hz
Power	240 W maximum; also "220 W maximum for all line and load conditions"	125 W maximum
Current	4.0 A maximum for all line and load conditions	4 A
Surge voltage	300 V RMS for 100 ms
Peak inrush current	40 A

The 5200 and 5300 manual gives 125 W and 2.5 A for those models.

Physical and environmental

Item	Service manual	Specification pages
Height	17.5 in (445 mm)	17.5 in
Width	16 in (406 mm)	15.1 in
Depth	15.1 in (383 mm)	16 in
Weight	17 lb without CD-ROM; "19 lb. (21.15 kg)" with CD-ROM	45 lb
Operating temperature	10–40 °C (50–104 °F)
Storage temperature	−40 to +47 °C for six months; −40 to +65 °C in transit for 72 hours
