The '''Macintosh Performa 5280''' is an all-in-one personal computer manufactured by Apple Computer, Inc., introduced on November 12, 1996.<ref>{{cite web |url=https://everymac.com/systems/apple/mac_performa/specs/mac_performa_5280_120.html |title=Apple Macintosh Performa 5280/120 Specs |publisher=EveryMac.com |access-date=2026-02-10}}</ref> It is a faster variant of the [[Macintosh Performa 5260CD|Performa 5260CD]] with a 120 MHz PowerPC 603e processor and 8X CD-ROM drive, sold exclusively in Japan.
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.<ref name="ts5280">{{cite web |url=https://support.apple.com/en-us/112326 |title=Macintosh Performa 5280: Technical Specifications |publisher=Apple |access-date=2026-09-30}} Source for the introduction date, "not sold in the U.S.", 40 MHz bus, optional level 2 cache, 4.5 V alkaline battery, 45 lb, System 7.5.3 and the 8x CD-ROM speed.</ref> 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.<ref name="ss526basics">Apple Computer, ''Power Macintosh/Performa 5260, 5280 Series'' Service Source, 1997, cover (models covered) and Basics chapter, p. 2 ("5260/120 and 5280").

The Performa 5280 is identical to the Performa 5260/120, but shipped with a different software bundle. The educational version, the [[Power Macintosh 5260|Power Macintosh 5260/120]], was sold in North America.<ref>{{cite web |url=https://en.wikipedia.org/wiki/Power_Macintosh_5260 |title=Power Macintosh 5260 |publisher=Wikipedia |access-date=2026-02-10}}</ref>
The 5260 and 5280 look like the [[Macintosh Performa 5200CD|Performa 5200]] and [[Macintosh Performa 5300CD|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.<ref name="ss526ev">Apple Computer, ''Power Macintosh/Performa 5260, 5280 Series'' Service Source, 1997, Exploded View, p. 1.

RAM cannot be interleaved on this system. 1 MB of system RAM is permanently dedicated to video function.
Apple's power figures for this family do not agree with each other.

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]

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.

Service notes

[edit | edit source]

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:
