			'''Apple's own weight figure for this chassis is internally contradictory and should not be quoted.''' It prints "Without CD-ROM: 17 lb. With CD-ROM: 19 lb. (21.15 kg)" — 19 lb is 8.6 kg, not 21.15 kg, and 17/19 lb is what the '''LC 630''' volume gives for a much smaller machine. The 21 kg / ~47 lb figure is the plausible one for a 15-inch all-in-one, and that is what this page carries, but it is flagged rather than presented as Apple's.

			'''Apple's built-in display figures''' for the 5260 and 5280: '''14-inch shadow mask, 12.8-inch viewable'''; dot pitch '''0.28 mm'''; vertical frequency '''66.7 Hz'''; active raster '''9.5 × 7.3 in'''; white point '''9,300 K'''; shipping brightness '''25 foot-lamberts'''; aluminised '''P22''' phosphor. Apple gives one video mode: '''640 × 480 at 16-bit colour'''. Note the '''14-inch''' tube — the 5200 and 5300 are 15-inch, and the two families are otherwise very similar.

			'''There is no high-voltage adjustment for this family.''' Apple publishes one for the 5200 and 5300 and marks every page of it "not for 5260, 5280". The Adjustments chapter here is '''Geometry''' and '''Video''' only, and Apple publishes '''no rail tolerance and no power-supply adjustment'''. The "+5 V 4.85–5.15 V / +12 V 11.90–12.75 V" pair that circulates on this wiki is Apple's Macintosh Plus and 128K/512K procedure with voltage test cable 077-0135.<ref name="ss5260" />

			'''Note also the different supply rating.''' Apple gives this family '''240 W''' and '''4.0 A''' maximum against '''125 W''' and '''2.5 A''' for the 5200 and 5300, in the same-looking chassis — so a 5200-series supply is not a drop-in for a 5260.

			The '''Macintosh Performa 5270CD''' is an all-in-one personal computer manufactured by Apple Computer, Inc., introduced on April 22, 1996.<ref>{{cite web \|url=https://everymac.com/systems/apple/mac_performa/specs/mac_performa_5270cd.html \|title=Apple Macintosh Performa 5270CD Specs \|publisher=EveryMac.com \|access-date=2026-02-10}}</ref> It is identical to the [[Macintosh Performa 5260CD\|Performa 5260CD]] but was marketed specifically for Asian and European markets under a different model designation.

			The Performa 5270CD features a 100 MHz PowerPC 603e processor with a 1.2 GB hard drive and 4X CD-ROM drive, housed in the same all-in-one chassis as its predecessor, the [[Macintosh Performa 5200CD\|Performa 5200CD]]. The educational version, the [[Power Macintosh 5260\|Power Macintosh 5260/100]], was sold in North America and also to the consumer market in Asia and Australia.<ref>{{cite web \|url=https://en.wikipedia.org/wiki/Power_Macintosh_5260 \|title=Power Macintosh 5260 \|publisher=Wikipedia \|access-date=2026-02-10}}</ref>

			== Differences from Performa 5260CD ==

			The Performa 5270CD is functionally identical to the [[Macintosh Performa 5260CD\|Performa 5260CD]] with the same specifications. The only differences are:

			* '''Market:''' Sold exclusively in Asia and Europe
			* '''Model Number:''' M4796J/A (Japan)
			* '''Software Bundle:''' Region-specific bundled software

			== Architecture and Processor ==

			The Performa 5270CD uses the PowerPC 603e processor running at 100 MHz with a 40 MHz system bus.<ref>{{cite web \|url=https://everymac.com/systems/apple/mac_performa/specs/mac_performa_5270cd.html \|title=Apple Macintosh Performa 5270CD Specs \|publisher=EveryMac.com \|access-date=2026-02-10}}</ref> The 603e is a 32-bit processor with a 64-bit data path and includes an integrated floating-point unit.
