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
[edit | edit source]Processor and Memory
[edit | edit source]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
[edit | edit source]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
[edit | edit source]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
[edit | edit source]The system has a single 601 PDS or 7" NuBus slot (NuBus available with PDS-to-NuBus adapter M1402LL/A).
Networking
[edit | edit source]AAUI-15 Ethernet is standard. Two Geoport serial ports (printer and modem) are included.
Case Design
[edit | edit source]The 6100 uses the low-profile Macintosh Centris 610 case form factor.
General Maintenance

Troubleshooting

Capacitor Replacement Guide
[edit | edit source]For capacitor replacement guidelines, see the Capacitor Replacement Guide.
Service documentation
[edit | edit source]Apple's own service manual is hosted here as Power Macintosh 6100/ WS 6150 Service Source. It gives the 6100/60 and WS 6150 as a PowerPC 601 at 60 MHz with built-in MMU and FPU and a 32K on-chip cache, requiring system software 7.1.2 or later; an A/C line input of 100–240 VAC RMS single phase, automatically configured, at 50–60 Hz; 132 W maximum continuous input, 201 W peak excluding the monitor; a power supply DC output of 86 W continuous; and the PRAM cell threshold as replace below 3.2 V.[2]
Its Basics chapter prints the HDI-45 pinout along with the rear panel and logic board connector maps — the HDI-45 pinout appears in only three Apple volumes (the 6100, 7100 and 8100) and is how you work out what an AV monitor cable is actually carrying.[2]

Apple service data
[edit | edit source]Apple's own figures, from the Power Macintosh 6100/WS 6150 Service Source volume hosted on this wiki.[3]
| Item | Apple's figure |
|---|---|
| Processor | PowerPC 601 at 60 MHz (6100/60, 6150) or 66 MHz (6100/66, 6150/66), with built-in MMU and FPU and 32K of on-chip cache. The 60 MHz machines need system software 7.1.2 or later, the 66 MHz machines 7.5 or later |

| VRAM | None. Video on the 6100/60, 6100/66, 6150 and 6150/66 is DRAM-based off the logic board; only the Power Macintosh AV card carries VRAM, 2 MB of it |
| Level 2 cache | Optional 256K on the 6100/60 and 6150; standard 256K on the 6100/66 |
| Video port | One HDI-45 DRAM-based video port for direct connection to Apple AudioVision monitors.

There is no VRAM in a non-AV 6100, so "replace the VRAM" is not a repair step on this machine. A video fault on a plain 6100 is the logic board, the HDI-45 adapter or the monitor.[3]
On DOS Compatible models, Apple's symptom chart for a black screen at boot or errors in DOS is to remove the DOS Compatibility card and check that the jumper is in the "SX" position, over the two right-most prongs, before replacing anything.[3]
