The Macintosh Performa 5280 is an all-in-one Macintosh with a 120 MHz PowerPC 603e and a built-in 14-inch display, which Apple sold in Japan. Apple's technical-specification page dates it to November 12, 1996.[1] Apple services it with the Power Macintosh 5260/100 and 5260/120 and the international Performa 5260/120 in one manual, which describes the 5260/120 and 5280 as the same machine: the 5260/100 with a 120 MHz processor, 16 MB of RAM and an AppleCD 1200i drive. The Performa 5260/120 was sold in Canada and Australia and the Power Macintosh 5260/120 in the United States and Canada.[4] EveryMac gives the Japanese order number as M5182J/A.[2]
The 5260 and 5280 look like the Performa 5200 and 5300 but are a separate design. The display is a 14-inch tube where the 5200 and 5300 have a 15-inch one, and the logic board, power supply board, analogue/video board and CRT all carry different Apple part numbers. Apple's 5200/5300 manual is marked "not 5260, 5280" on its cover.[5][6]
Specifications
| Item | Specification |
|---|---|
| Processor | PowerPC 603e at 120 MHz with integrated FPU; 64-bit PowerPC bus[3] |
| Cache | 32 KB level 1. The Service Source lists 256K of level 2 cache; Apple's technical-specification page lists level 2 cache as optional[3][1] |
| ROM | 4 MB[3] |
| RAM | 16 MB minimum in 72-pin, 80 ns fast-page-mode SIMMs; two slots, 64 MB maximum[3][4] |
| Video | 1 MB DRAM frame buffer on the logic board; 640 × 480 at 16-bit is the only mode for the built-in display[3] |
| Display | 14-inch shadow mask, 12.8-inch viewable image; 0.28 mm dot pitch; 66.7 Hz vertical; 9,300 K white point[3] |
| Storage | 800 MB, 1.2 GB or 1.6 GB IDE hard drive; AppleCD 1200i CD-ROM; 1.4 MB Apple SuperDrive, manual insert[3] |
| Sound | 16-bit mono input (stereo input is combined to mono); 16-bit stereo output, nominally 0.5 V RMS into 39 ohms; internal speakers deliver 16-bit stereo[3] |
| Ports | Two RS-232/422 serial ports (mini DIN-8); one SCSI port (DB-25, up to seven devices); one ADB port; DB-15 mirror video output with the optional video connector kit (640 × 480)[3] |
| Expansion | 96/114-pin LC processor-direct slot; 112-pin communications slot (68040-bus); 60-pin video-in slot; 10-pin TV tuner port[3] |
| Power | 100–240 V AC, 47–63 Hz. Surge 300 V RMS for 100 ms; peak inrush 40 A; 4.0 A maximum for all line and load conditions[3] |
| Clock battery | 4.5 V alkaline pack on a connector; replace below 3.0 V[1][7] |
Apple's power figures for this family do not agree with each other. The Service Source Electrical page gives "240 W maximum" on its power line and "220 W maximum for all line and load conditions" two lines below; Apple's technical-specification page gives 125 W and 4 A.[3][1] The Service Source weight entry ("With CD-ROM: 19 lb. (21.15 kg)") is also inconsistent, and the technical-specification page gives 45 lb. Treat the power figures as a guide only.
Service notes
Apple's service parts for the 5260/5280 family are the power supply board 661-1133, the analogue/video board assembly 661-1134, the CRT assembly 661-1135, and logic boards 661-1116 (100 MHz) and 661-1265 (120 MHz). None of these is a 5200/5300 part number.[5]
The 5260/5280 logic board has a Cuda reset button. Apple's first step for a machine that will not start is a logic board reset: remove the logic board, unplug the battery, wait 5 to 10 minutes, refit the battery, press the Cuda reset switch with a plastic tool and refit the board. The next step is a new power supply board.[7][8] A machine that starts from the rear switch but not from the keyboard, or restarts after Shut Down, has a faulty analogue board.[8]
The Adjustments chapter covers light meter setup, geometry and video only. The high-voltage adjustment in the 5200/5300 manual is marked "not for 5260, 5280" and does not apply to this machine.[9][6] The CRT holds a charge after the machine is unplugged; read CRT Discharge Procedure before opening it. The clock battery is alkaline, so leakage is neutralised with dilute white vinegar; see Battery Explosion, Capacitor or Corrosion Damage.
The Performa 5200CD guides cover the general procedures for this style of machine. Their part numbers and high-voltage adjustment are for the 5200/5300 and do not apply to the 5280:
