The Macintosh Performa 6200 is a PowerPC-based desktop computer introduced by Apple Computer on July 11, 1995. It is the non-CD-ROM variant of the Performa 6200CD, sharing the same logic board and case design but without the CD-ROM drive.
Differences from Performa 6200CD
[edit | edit source]The Performa 6200 differs from the Performa 6200CD only in the absence of the CD-ROM drive, offering a lower-cost entry point for consumers who did not require optical media.
Architecture and Processor
[edit | edit source]The Performa 6200 uses a PowerPC 603 processor running at 75 MHz with integrated FPU.
Cache Configuration
[edit | edit source]- L1 Cache: 16 KB on the PowerPC 603 (8 KB instruction, 8 KB data)
- L2 Cache: 256 KB[1]
Memory and Storage
[edit | edit source]RAM Configuration
[edit | edit source]| Specification | Details |
|---|---|
| RAM Type | 72-pin SIMM |
| Minimum Speed | 80 ns or faster[1] |
| Standard RAM | 8 MB minimum, fitted in one SIMM slot; none is soldered to the board[1] |
| Maximum RAM | 64 MB across two SIMM slots[1] |
| RAM Slots | 2[1] |
| ROM | 4 MB[1] |
The 1 MB video frame buffer is separate DRAM on the logic board, not a slice of system RAM. Apple's specification reads "DRAM Frame Buffer: 1 MB DRAM on board, for video support".[1] Fitting more system memory does not change the available video memory, and the machine does not lose 1 MB of its 8 MB to video.
Storage Systems
[edit | edit source]- Hard Drive: 1.0 GB IDE internal drive
- Floppy Drive: 1.44 MB 3.5" manual-inject
Display and Graphics
[edit | edit source]- Standard Resolution: 640×480 at 16-bit color
- Extended Resolution: 800×600 or 832×624 at 8-bit color
- Frame buffer: 1 MB of dedicated DRAM on the logic board[1]
Apple's Repair Extension Program
[edit | edit source]Apple ran a genuine Repair Extension Program covering system freezes and sudden changes in video colour hue on the Performa 62xx family. The published checks are specific:[1]
| What to check | Where | What is wrong | Apple's remedy |
|---|---|---|---|
| Clock chip | U10 | Part number is not 343S1191 or 343S1121 (ignore trailing letters) | Replace the logic board |
| Cache/ROM DIMM | Vertical DIMM on the logic board | Laid out as in Apple's figure and no sticker on the middle vertical IC | Replace the DIMM, part 661-1278 |
| Version B logic board | U6, with U27 on the underside | U6 carries no picture of Texas and is p/n 343S0138-a, and there is no wire at U27 | Replace the logic board |
| Ethernet card fence | Communications slot | Fence does not hook onto the logic board fence | Replace the fence — otherwise the card rocks out of the slot and the network drops intermittently |
| Internal RGB cable | Between logic board and video board | Sudden or intermittent colour-hue changes | Replace the internal RGB cable |
A "Version B" board shows a B at the end of the serial number printed near the communications port. Apple's diagnostic application for the programme was 5XXX/6XXX Tester, shipped on the Service Source Companion CD; it tests for the freeze-related component issues but not for colour-hue faults.[1]
Apple also directs Type 11 errors away from this programme and towards a clean system install or a third-party software update.[1]
Power
[edit | edit source]| Specification | Value |
|---|---|
| Line voltage | 100–240 VAC[1] |
| Frequency | 47–63 Hz[1] |
| Power | 125 W. Surge voltage 300 V RMS for 100 ms; peak inrush 40 A; 2.5 A maximum and 220 W maximum for all line and load conditions[1] |
Apple publishes no per-rail voltages, no rail tolerances and no power-supply adjustment procedure for this machine.
General Maintenance
[edit | edit source]For detailed maintenance practices, refer to the dedicated Macintosh Performa 6200CD General Maintenance page.
Capacitor Replacement Guide
[edit | edit source]Detailed capacitor replacement guidelines can be found on the Macintosh Performa 6200CD Capacitor Replacement Guide page.
Troubleshooting
[edit | edit source]A comprehensive troubleshooting guide is available on the Macintosh Performa 6200CD Troubleshooting page.
Service documentation
[edit | edit source]Apple's own service manual is hosted here as Performa 6200/6300 Series Service Source. It gives the Performa 6200 as a PowerPC 603 at 75 MHz, a 100–240 VAC supply at 47–63 Hz drawing 125 W with a 300 V RMS 100 ms surge rating and a 40 A peak inrush, and the PRAM cell threshold as replace below 3.0 V. The Performa 6360 is electrically a different machine and is specified separately throughout: 90–270 VAC, 43–67 Hz, 150 W.[2]
That volume contains a chapter that exists almost nowhere else in Apple's set: REA Procedures, Apple's Repair Extension Authorisation for the freezing and video colour-hue faults these machines became known for, with a repair overview, a System Tester, part numbers and an "Install System 7.5.3" step. It is Apple's own account of the problem rather than a rumour.
Do not quote the PDF's internal creation date: it reads 2 September 1956, which is impossible and is an Acrobat Distiller artefact.[2]
