The '''Macintosh Performa 560''' is an all-in-one personal computer introduced by Apple Computer on January 1, 1994.<ref>{{cite web |url=https://everymac.com/systems/apple/mac_performa/specs/mac_performa_560.html |title=Macintosh Performa 560 Specs |publisher=EveryMac.com |access-date=2026-02-10}}</ref> It is identical to the [[Macintosh Performa 550|Performa 550]] and [[Macintosh LC 550|LC 550]] in hardware, differing only in the bundled "business software" package.

== Relationship to LC 550 and Performa 550 ==

The Performa 560 uses the same logic board, case design, and internal components as the [[Macintosh LC 550|LC 550]] and [[Macintosh Performa 550|Performa 550]]. Apple marketed the same hardware under different names for different markets:

* '''[[Macintosh LC 550|LC 550]]''' – Educational market
* '''[[Macintosh Performa 550|Performa 550]]''' – Consumer market (home software bundle)
* '''Performa 560''' – Consumer market (business software bundle)

The higher price of the Performa 560 reflected the different software bundle rather than any hardware differences.

== Architecture and Processor ==

The Performa 560 uses a Motorola 68030 processor running at 33 MHz with a 32-bit data bus. The system bus also operates at 33 MHz. An optional Motorola 68882 FPU can be installed for floating-point calculations.

== Memory and Storage ==

=== RAM Configuration ===

The system includes 4 MB of RAM soldered to the logic board, with an additional 1 MB SIMM installed by default for a total of 5 MB. A single 72-pin SIMM slot accepts modules up to 32 MB for a maximum of 36 MB total RAM. SIMMs must be 80 ns or faster.

=== ROM ===

The Performa 560 contains 1 MB of ROM.

=== Storage Systems ===

Standard configuration includes a 160 MB internal SCSI hard drive, a 2X CD-ROM drive, and a 1.44 MB SuperDrive floppy.

== Display and Graphics ==

The built-in 14-inch Sony Trinitron CRT displays 640×480 resolution in 16-bit color. The system includes 512 KB of VRAM soldered to the logic board. A single VRAM slot accepts a 256 KB VRAM SIMM, bringing the total to 768 KB for improved color depth.

A second display can be supported via an LC PDS video card.

== Input/Output and Expansion ==

=== Port Configuration ===

* 2× Serial ports (Printer, Modem)
* SCSI port (DB-25)
* ADB port
* Audio input/output jacks

=== Expansion ===

The Performa 560 includes one LC PDS slot for expansion cards such as Ethernet adapters or additional video output.

== General Maintenance ==

For detailed maintenance practices including cleaning, PRAM battery management, connector corrosion prevention, and voltage adjustments, refer to the dedicated [[Macintosh LC 550 General Maintenance]] page.

== PCB Schematics & Service Manual ==

The Macintosh Performa 560 shares its logic board and analog board with the [[Macintosh LC 550|LC 550]]. For schematics and service documentation, see the [[Macintosh LC 550]] article.

All Apple Service Manuals can be found on the [[:Category:Apple Service Source|Apple Service Source]] page.

== Capacitor Replacement Guide ==

Detailed capacitor replacement guidelines for both analog and logic boards can be found on the [[Macintosh LC 550 Capacitor Replacement Guide]] page.

== Retrobrite ==

To address plastic yellowing, detailed instructions can be found on the [[Retrobrite]] page.

== Troubleshooting ==

A comprehensive troubleshooting guide addressing no power, chime but no video, intermittent operation, Sad Mac errors, and floppy drive problems is available on the [[Macintosh LC 550 Troubleshooting]] page.
