Red-link sweep: retarget delegation links to the pages that actually exist (LC 550/LC 580/Performa 6100 sub-pages do not, the Performa 550/580 and Power Macintosh 6100 ones do), fix the malformed 'Macintosh Power Macintosh 5400' title, and de-link targets with no page
Rewrite on the 6100/WS 6150 SS, Apple spec pages and Apple developer notes: all five models with Apple dates, bus clocks, 601 unified cache (Motorola), Apple service notes; remove duplicated service-data block; Commons photo with credit

! Model !! Introduced !! Discontinued !! Processor / bus !! Level-2 cache !! Hard drive !! Notes
=== 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.
| 6100/60 || March 14, 1994 || January 3, 1995 || 60 / 30 MHz || Optional 256 KB || 160 or 250 MB || CD-ROM optional
 
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.

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'''.<ref name="sspowermacintosh61">Apple Computer, ''Power Macintosh 6100/WS 6150'', Service Source, 160 pp, PDF distilled 2 January 1996.

The Power Macintosh 6100 is a desktop Macintosh with a PowerPC 601 processor in the low-profile case of the Macintosh Centris 610. Apple introduced the 6100/60 and 6100/60AV on March 14, 1994, with the 7100/66 and 8100/80, as its first Power Macintosh computers. The 66 MHz 6100/66, 6100/66AV and 6100/66 DOS Compatible followed on January 3, 1995.[1][2][3][4] The consumer versions were the Performa 6100 series, and the server version was the Workgroup Server 6150.[5]

Video DRAM-based video on the logic board through one HDI-45 port; no VRAM. An HDI-45 to DB-15 adapter was supplied. The AV card adds 2 MB of VRAM, a DB-15 port and S-video/composite input and output
Storage Internal SCSI hard drive; optional internal CD-ROM; 1.4 MB SuperDrive, manual insert
Ports Two serial (RS-232/RS-422, LocalTalk/GeoPort, mini DIN-9, accept mini DIN-8 plugs); one ADB (500 mA maximum, three devices); one SCSI (DB-25, six external devices, five with an internal CD-ROM); AAUI-15 Ethernet; stereo sound in and out
Expansion One slot taking a processor-direct card, or a 7-inch NuBus card with an adapter; filled by the AV card on AV models
Sound 16-bit stereo in and out; 48, 44.1, 24 and 22.05 kHz; line level 1 V peak to peak; 82 dB signal-to-noise; THD+N under 0.05 %
Electrical 100–240 V AC, 50–60 Hz, automatically configured; 132 W continuous and 201 W peak input, excluding the monitor; 86 W continuous DC output
Clock battery Long-life lithium battery in a holder on the logic board; replace below 3.2 V

Sources: service manual pp. 23–37, 69 and 103;[5] bus clocks from Apple's developer notes.[4][8] Apple's specification pages give the battery as 3.6 V lithium.[1]

The 601's 32 KB first-level cache is eight-way set-associative and unified: instructions and data share it.[11] Video uses part of main memory: EveryMac puts it at 640 KB.[9] Apple lists the displays the HDI-45 port drives with the adapter, from the 12-inch RGB (512 × 384) to the 16-inch Color Display (832 × 624) and the 15-inch Portrait (640 × 870) (p. 33).[5]

Service notes

[edit | edit source]

Apple's troubleshooting tips and symptom charts for the 6100 include several that catch people out:[5]

  • If the machine will not power up, reset the logic board before replacing anything: unplug it, take out the battery, press the power button, disconnect the power supply cable from the logic board for 5 to 10 minutes, then refit everything (pp. 6, 107–111).
  • Bad SIMMs do not produce the death chimes of earlier Macintosh models. A dialog box reports the bad SIMM instead (p. 7).
  • SIMMs must be noncomposite and fitted in like pairs. Mismatched pairs make About This Macintosh report more or less memory than is installed (pp. 6, 53).
  • The internal hard drive must be terminated and an internal CD-ROM must not be (p. 50).
  • A sticking power button is realigned, or the hole round it enlarged by 1/16 inch, before the bottom housing is replaced (p. 53).
  • A Multiple Scan monitor on a 6100/60AV that shows ghosting or smearing needs a new AV card (p. 44).
  • The jumper at J10 on the DOS Compatibility card is mismarked; it must be in the "SX" position, over the two right-most prongs (pp. 54, 134).

Leakage from the lithium clock battery is acidic; neutralise it with bicarbonate of soda. See Battery Explosion, Capacitor or Corrosion Damage.

Service documentation

[edit | edit source]

Apple's Power Macintosh 6100/WS 6150 Service Source (160 pages) covers the 6100/60, 6100/60AV, 6100/66, 6100/66AV, 6100 DOS Compatible and Workgroup Server 6150. It includes the HDI-45 pinout (pp. 9–14), symptom charts, take-apart procedures and an exploded view with part numbers, and has no schematics.[5]

Apple's developer notes describe the hardware for card and software designers: one for the 6100/60 (1994) and a supplement for the 6100/66, 7100/80 and 8100/100 (1994).[4][8] The Performa 6100 series has its own Service Source, File:Performa 6100 series.pdf.
