The Macintosh Performa 6110CD is the first model of Apple's Performa 6100 series, the consumer versions of the Power Macintosh 6100/60, introduced on 1 November 1994.[1] Apple's service manual for the series lists six models, the 6110CD, 6112CD, 6115CD, 6116CD, 6117CD and 6118CD, which have the same logic board and differ in hard drive size, bundled monitor, modem and software.[2] EveryMac describes the series as based on the Piltdown Man (PDM) design of the Power Macintosh 6100, and lists the 6110CD at US$2,600 with order number M3433LL/A.[3]

Introduction dates and drive sizes are from Apple's specification sheets; monitors and modems from Apple's service manual, which does not list the 6116CD's configuration; bundles, order numbers and prices from EveryMac.[1][2][3][4] EveryMac's pages for the other five models give the bundles, order numbers and prices.[5]

Specifications

Performa 6100 series specifications (Apple)
Item Specification
Processor PowerPC 601 at 60 MHz with built-in MMU and FPU and 32K of on-chip cache; needs System 7.5 or later[2]

ROM 4 MB on a SIMM socket[2]
Cache 32K on the processor; optional 256K level 2 cache[2]
Drives 1.4 MB SuperDrive, manual insert; internal SCSI hard drive (250, 350, 500 or 700 MB by model); AppleCD 300i Plus CD-ROM drive[2][1]

Expansion One internal slot for a processor-direct card, or a 7-inch NuBus card with an adapter[2]
Electrical 100-240 V AC, automatically configured, 50-60 Hz; 210 W maximum input, not including the monitor; 86 W DC output[2]
Size and weight 85 × 415 × 399 mm; 6.4 kg (14.0 lb)[2]

EveryMac gives the video system 640K of main memory and notes that two third-party 64 MB SIMMs bring the total to 136 MB.[3] Apple's specification sheets list an Intel 486DX2-66 DOS card as an option.[1]

Hardware

The Performa 6100 series is serviced as a Power Macintosh 6100/60. Apple's Power Macintosh 6100/WS 6150 Service Source covers the same logic board and adds the procedures the Performa volume leaves out.[6]

SIMMs go in matched pairs of the same size and speed and must be non-composite; when About This Macintosh reports more or less memory than is fitted, Apple's first check is the pairing.[2]

The battery is a 3.6 V lithium cell on the logic board.[1] Apple's test is to measure it on the 10 V DC range and replace it below 3.2 V.[6] Neutralise leakage from a lithium cell with bicarbonate of soda; see Battery Explosion, Capacitor or Corrosion Damage.

For a machine that will not power up, Apple's first step is to reset the logic board: unplug the computer, take the battery out of its holder, press the power button, disconnect the power supply cable from the logic board and wait 5-10 minutes before refitting the battery and cable. This also clears PRAM.[6]

From Apple's symptom charts
Symptom Apple's cures, in order
System does not power up Reset the logic board; reseat the ROM SIMM and cache SIMM; replace the power supply; replace the logic board[2]
Crashes or hangs Check for System 7.5 or later; check the SIMMs are non-composite and in like pairs; check the software; zap PRAM; replace the SIMMs, then the logic board, then the power supply[2]
Dark screen, fan running, no drive activity Reset the logic board; reseat the ROM and cache SIMMs; remove peripherals; replace the DRAM SIMMs, then the power supply, then the logic board[2]
Power button sticks Realign the plastic button; reseat the power supply; enlarge the hole round the button by 1/16 in; bend down the guide tabs in the bottom housing[6]
Modem software reports a busy port or cannot find the modem Install the GlobalFax 2.5.2P update, or replace the TelePort control panel from the backup CD, with AppleTalk active and LocalTalk selected[6]
