Macintosh Performa 5270CD
The Macintosh Performa 5270CD is an all-in-one Macintosh with a 100 MHz PowerPC 603e and a built-in 14-inch monitor. Apple gives its introduction date as April 15, 1996 and says it was not sold in the US. Its figures are those of the Performa 5260CD with a 1.2 GB hard drive.[1] EveryMac gives April 22, 1996 for the introduction and February 1, 1997 for the discontinuation, lists order number M4796J/A, and says it was sold in Asia and Europe.[2] Apple's Service Source for the 5260 and 5280 covers the same hardware as the Power Macintosh 5260/100.[3] Apple's technical specifications give 8 MB as the minimum RAM; the Service Source gives 16 MB for the whole family.[1]

The 5260 looks like the 5200 series but its logic board (661-1116 at 100 MHz, 661-1265 at 120 MHz), power supply board (661-1133), analogue/video board (661-1134) and CRT (661-1135) all have different part numbers from the 5200's (p. 216).[3][4] The 5200 series has a 15-inch tube and a 125 W, 2.5 A supply; the 5260 has a 14-inch tube and a 240 W, 4.0 A supply. Apple's 5200 manual marks every adjustment page "not for 5260, 5280".[4][3]
The processor-direct slot takes many cards made for the Macintosh LC, but Apple says it is not a true PDS: cards that work with the main processor, such as cache or FPU cards, do not work (p. 11).[3] A Cuda microcontroller handles soft power, resets, PRAM, ADB and the real-time clock; Apple says many system problems clear after pressing the Cuda reset button on the logic board (pp. 21, 178).[3]
The PRAM battery connects to the logic board by a plug and sits on hook-and-loop tape. Apple's test is to replace it below 3.0 V (pp. 174–177); Apple's technical specifications give the battery type as 4.5 V alkaline.[3][1]
Adjustments
Apple's adjustments for the 5260 and 5280 are light meter setup, geometry, video and power supply. Apple requires the power-supply adjustment whenever the analogue board or power supply is taken out: connect a DC voltmeter between the metal chassis and pin 3 of P805 on the power supply, and set R828 for 110 V DC (pp. 213–214).[3] The 5200 series high-voltage adjustment (29.5 V at D713 or D703) does not apply.[4]
The power supply and analogue board carry mains and CRT voltages, and the power-supply adjustment is made with the machine running. Discharge the CRT before working near it; see CRT Discharge Procedure.
Maintenance and repair
Apple's symptom charts for this family are in its Service Source.[3] The 5200 series guides cover the same kind of chassis, but their board part numbers and the high-voltage adjustment do not apply to the 5260:
