The '''Macintosh Performa 5260CD''' 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_5260cd.html |title=Apple Macintosh Performa 5260CD Specs |publisher=EveryMac.com |access-date=2026-02-10}}</ref> It features a 100 MHz PowerPC 603e processor in the same all-in-one chassis as its predecessor, the [[Macintosh Performa 5200CD|Performa 5200CD]].

The Performa 5260 series replaced the PowerPC 603 CPU with the improved 603e. The system shares its logic board and form factor with the education-market Power Macintosh 5260/100 and various regional variants sold under different model numbers.<ref>{{cite web |url=https://en.wikipedia.org/wiki/Power_Macintosh_5260 |title=Power Macintosh 5260 |publisher=Wikipedia |access-date=2026-02-10}}</ref>

== Model Variants ==

The Performa 5260 family includes several regional and speed variants:

<templatestyles src="Template:StyledTable/styles.css" />
{| class="wikitable styled-table" style="width:100%; text-align:center;"
|+ '''Performa 5260/5280 Series Variants'''
|-
! Model !! CPU Speed !! Hard Drive !! CD-ROM !! Introduction !! Region
|-
| '''Performa 5260CD''' || 100 MHz || 800 MB or 1.2 GB || 4X || April 22, 1996 || Worldwide
|-
| '''Performa 5270CD''' || 100 MHz || 1.2 GB || 4X || April 22, 1996 || Asia, Europe
|-
| '''Performa 5280''' || 120 MHz || 1.2 GB || 8X || November 12, 1996 || Japan
|}

The Performa 5270CD is identical to the 5260CD with a different model designation for Asian and European markets. The Performa 5280 is a later variant with a faster 120 MHz CPU and 8X CD-ROM drive, sold exclusively in Japan.

== Architecture and Processor ==

The Performa 5260CD uses the PowerPC 603e processor running at 100 MHz with a 40 MHz system bus.<ref>{{cite web |url=https://support.apple.com/kb/SP298 |title=Macintosh Performa 5260CD: Technical Specifications |publisher=Apple Inc. |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.

=== Cache Configuration ===
* '''L1 Cache:''' 32 KB (16 KB instruction + 16 KB data)
* '''L2 Cache:''' 256 KB (optional expansion slot)

=== ROM ===
The system includes 4 MB of ROM in a "New World" ROM-in-RAM configuration.

== Memory and Storage ==

=== RAM Configuration ===
{| class="wikitable styled-table" style="width:70%; text-align:center;"
|-
! Specification !! Details
|-
| '''RAM Type''' || 72-pin SIMM
|-
| '''Minimum Speed''' || 80 ns
|-
| '''Standard RAM''' || 8 MB or 16 MB
|-
| '''Maximum RAM''' || 64 MB
|-
| '''RAM Slots''' || 2
|}

RAM cannot be interleaved on this system. 1 MB of system RAM is permanently dedicated to video function.

=== Storage Systems ===
* '''Hard Drive:''' 800 MB or 1.2 GB IDE internal drive
* '''Floppy Drive:''' 1.44 MB 3.5" manual-inject
* '''CD-ROM:''' 4X (5260CD/5270CD) or 8X (5280)

The system uses an IDE interface for the hard drive; internal SCSI hard drives are not supported.

== Display and Graphics ==

The Performa 5260CD features a built-in 14" Shadow Mask RGB CRT display running at 640×480 resolution with 16-bit color (thousands of colors). Video memory consists of 1 MB dedicated from system RAM and cannot be expanded.<ref>{{cite web |url=https://everymac.com/systems/apple/mac_performa/specs/mac_performa_5260cd.html |title=Apple Macintosh Performa 5260CD Specs |publisher=EveryMac.com |access-date=2026-02-10}}</ref>

An external display can be connected via an optional LC PDS video card.

== Audio Capabilities ==

The system provides 16-bit mono sound input through the rear audio input jack. Standard Macintosh sound output is provided through built-in speakers and a rear audio output jack.

== Input/Output and Expansion ==

=== Port Configuration ===
{| class="wikitable styled-table" style="width:70%; text-align:center;"
|-
! Port Type !! Quantity !! Notes
|-
| '''ADB''' || 1 || Apple Desktop Bus for keyboard and mouse
|-
| '''Serial''' || 2 || Printer and modem ports (no hardware handshaking)
