The '''Power Macintosh 6100''' is a personal computer introduced by Apple Computer on March 14, 1994.<ref>{{cite web |url=https://everymac.com/systems/apple/powermac/specs/powermac_6100_60.html |title=Power Macintosh 6100/60 Specs |publisher=EveryMac.com |access-date=2026-02-10}}</ref> It was one of the first three Power Macintosh models released, alongside the [[Power Macintosh 7100]] and [[Power Macintosh 8100]], marking Apple's transition from Motorola 68k processors to the PowerPC architecture. Based on the "PDM" (Piltdown Man) architecture, the 6100 used the same low-profile desktop case as the [[Macintosh Centris 610]] and [[Macintosh Quadra 610]].

== Model Variants ==
The consumer version is the [[Macintosh Performa 6110CD|Performa 6110CD]] and related models, and the server version is the Workgroup Server 6150/60.


The Power Macintosh 6100 was available in two processor configurations with various sub-models:

|}


=== DOS Compatible Version ===
RAM uses 72-pin SIMMs at 80 ns minimum speed. The system has 8 MB of onboard RAM and 2 SIMM slots (SIMMs must be installed in matching pairs). Maximum RAM is officially 72 MB, but can reach 136 MB with two 64 MB SIMMs plus the onboard memory. 640K of system RAM is dedicated to video function.


A PC-compatible version was also available, featuring a 66 MHz Intel 486DX2 processor on a NuBus card. This allowed users to run DOS and Windows alongside Mac OS. The PC card could be configured with up to 32 MB of dedicated RAM.
=== Storage ===
The system includes a 160 MB or 250 MB internal SCSI hard drive. A 2X CD-ROM drive is optional (standard in some configurations). A 1.44 MB floppy drive is standard.

The Power Macintosh 6100 is a desktop Macintosh computer based on the PDM (Piltdown Man) architecture, released on March 14, 1994.[1] It was one of the first Power Macintosh computers, featuring a PowerPC 601 processor running at 60 MHz.

The consumer version is the Performa 6110CD and related models, and the server version is the Workgroup Server 6150/60.

Hardware Overview

Processor and Memory

The Power Macintosh 6100 uses a PowerPC 601 processor at 60 MHz with a 30 MHz system bus. It has a 32-bit processor with a 64-bit data path. The system includes 32K of L1 cache and supports optional 256K L2 cache.

RAM uses 72-pin SIMMs at 80 ns minimum speed. The system has 8 MB of onboard RAM and 2 SIMM slots (SIMMs must be installed in matching pairs). Maximum RAM is officially 72 MB, but can reach 136 MB with two 64 MB SIMMs plus the onboard memory. 640K of system RAM is dedicated to video function.

Storage

The system includes a 160 MB or 250 MB internal SCSI hard drive. A 2X CD-ROM drive is optional (standard in some configurations). A 1.44 MB floppy drive is standard.

Display

The system supports a single external display at 512×394 or 640×480 at 16-bit, or 832×624 at 8-bit. A second display can be added with an expansion video card.

Expansion

The system has a single 601 PDS or 7" NuBus slot (NuBus available with PDS-to-NuBus adapter M1402LL/A).

Networking

AAUI-15 Ethernet is standard. Two Geoport serial ports (printer and modem) are included.

Case Design

The 6100 uses the low-profile Macintosh Centris 610 case form factor.

General Maintenance

For detailed maintenance practices, refer to the General Maintenance page (shared hardware with Performa 6100 series).

Troubleshooting

For troubleshooting information, see the Troubleshooting page.

Capacitor Replacement Guide
