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 [[Macintosh Performa 6200CD|Performa 6200CD]], sharing the same logic board and case design but without the CD-ROM drive.

== Differences from Performa 6200CD ==

The Performa 6200 differs from the [[Macintosh Performa 6200CD|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 ==

The Performa 6200 uses a PowerPC 603 processor running at 75 MHz with integrated FPU.

=== Cache Configuration ===
* '''L1 Cache:''' 16 KB on the PowerPC 603 (8 KB instruction, 8 KB data)
* '''L2 Cache:''' 256 KB<ref name="ss62">Apple Computer, Inc., ''Performa 6200/6300 Series Service Source'', Specifications, Troubleshooting &rarr; Symptom Charts, Additional Procedures and REA Procedures &rarr; "Repair Overview for Freezing and Video Color Hue Issues". Hosted on this wiki as [[:File:Performa 6200.6300.pdf]].</ref>

== Memory and Storage ==

=== RAM Configuration ===
{| class="wikitable" style="width:70%; text-align:center;"
|-
! Specification !! Details
|-
| '''RAM Type''' || 72-pin SIMM
|-
| '''Minimum Speed''' || 80 ns or faster<ref name="ss62" />
|-
| '''Standard RAM''' || 8 MB minimum, fitted in '''one''' SIMM slot; none is soldered to the board<ref name="ss62" />
|-
| '''Maximum RAM''' || 64 MB across two SIMM slots<ref name="ss62" />
|-
| '''RAM Slots''' || 2<ref name="ss62" />
|-
| '''ROM''' || 4 MB<ref name="ss62" />
|}

'''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".<ref name="ss62" /> 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 ===
* '''Hard Drive:''' 1.0 GB IDE internal drive
* '''Floppy Drive:''' 1.44 MB 3.5" manual-inject

== Display and Graphics ==

* '''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<ref name="ss62" />

== Apple's Repair Extension Program ==

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:<ref name="ss62" />

<templatestyles src="Template:StyledTable/styles.css" />
{| class="wikitable styled-table"
! 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.<ref name="ss62" />

Apple also directs Type 11 errors away from this programme and towards a clean system
install or a third-party software update.<ref name="ss62" />

== Power ==

{| class="wikitable"
! Specification !! Value
|-
| Line voltage || 100–240 VAC<ref name="ss62" />
|-
| Frequency || 47–63 Hz<ref name="ss62" />
|-
| 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<ref name="ss62" />
|}

Apple publishes no per-rail voltages, no rail tolerances and no power-supply adjustment
procedure for this machine.
