Power Macintosh 6200
The Power Macintosh 6200 (also sold under variations of the name Performa 6200, Performa 6300 and Power Macintosh 6300) is a series of personal computers designed, manufactured, and sold by Apple Computer, Inc. from May 1995 to July 1997.  The 6200 is the PowerPC-based replacement for the Quadra 630, with the same form factor and price range. In early 1997, the rather different Power Macintosh 6300/160 / Performa 6360 based on the Power Macintosh 6400 was introduced. The whole line was discontinued when the desktop model of the Power Macintosh G3 was released.

In addition to the many Performa variants, it also includes model numbers above 6300 (which would normally indicate a different model). The model numbers above 6260 use a PowerPC 603e processor, but are otherwise virtually identical. Finally, some computers with model numbers that indicate they belong to the 6200/6300 family (the above-mentioned Power Macintosh 6300/160 and its Performa version 6360) are rather different on the inside. Generally, the 6200 and 6300 are closely related to the Power Macintosh 5200 LC and 5300 LC. For nearly every 6000-series (desktop) model, there is a 5000-series (all-in-one) model with an integrated CRT screen.

Power Macintosh 6200 / 6300 

The 6200 shares its logic board with the Power Macintosh 5200 LC. The internal bus structure consists of three buses:
 A 64-bit 75 MHz 603 bus connecting the CPU, 256K L2 cache, and ROM. This is the front-side bus.
 A 32-bit 37.5 MHz 68040 bus connecting the memory, video, and I/O controllers. A custom integrated circuit, Capella, bridged this bus to the 603 bus. Capella is very similar to a northbridge (computing) chip.
 A 32-bit 16 MHz I/O bus managed by a custom integrated circuit, PrimeTime II, which is similar to a southbridge (computing) chip.

On January 27, 1996, the 6300 and 6310 models were introduced, with a new 100 MHz PowerPC 603e CPU. On April 22, 1996, the 6320 and 6300/120 were released. These upgraded the CPU speed to 120 MHz. The 6300/120 was sold as a business model in the Asia market. In all cases the front-side bus speed matched the CPU speed, and the 68040 or northbridge (computing) bus speed was increased to 40 MHz. The rest of the logic board remained the same.

Models
Standard equipment on all 6200/6300 models includes an LC-PDS slot, a 1.4 MB SuperDrive with manual insert, two RS-232/422 serial ports, one external SCSI port, one ADB port, monophonic sound input port, internal stereo speakers, and a DB-15 video output port.  The internal modem is in a 112-pin expansion slot, allowing for aftermarket modems.  There is also an external modem port, but it is covered over by a piece of plastic. If the plastic seal is removed and the internal modem is removed, the external port is usable.

All machines also shipped with an AppleDesign keyboard, ADB Mouse II, and (excepting the 6216CD and 6220CD) an Apple Multiple Scan 15 Display.

Power Macintosh 6300/160 / Performa 6360 

The Power Macintosh 6300/160 (also sold as the Performa 6360) was introduced in October 1996. It retains the desktop form factor introduced with the 6200, but is built around the "Alchemy" motherboard that was first introduced with the Power Macintosh 5400/120. This board has a 64-bit data path and 64-bit DIMM RAM, PCI slot, and Comm Slot II (incompatible with the earlier Comm Slot). It also includes two GeoPort external serial ports. NuBus cards are not supported.

Standard equipment on the 6300/160 and 6360 include a 1.2 GB IDE hard drive, an 8X CD-ROM, full stereo input (unlike the 6200/6300 series, which combined stereo input into monophonic sound), one internal speaker (compared to two on the 6200/6300 series), and support for increased display resolutions with higher bit depth, notably 800x600 16-bit color at 60 Hz and 1024x768 8-bit color at 60 or 70 Hz.  The 6360's power supply unit is increased to 150 watts.

While the 6360 was designed from the start to support JEDEC-standard 5-volt, 64-bit, 168-pin, EDO 70ns DIMMs with a 2k refresh rate, the logic board did not initially support EDO RAM.  A user servicing the machine would need to examine the serial numbers on the on-board RAM to see whether EDO is supported. The 6360 has two DIMM slots, which can be populated by one or two chips of varying sizes up to 64 MB.  Combined with the on-board 8 MB RAM, this provides a maximum memory of 136 MB.  Because the board only supports linear memory organization, no performance benefit is provided if two chips of the same type are installed. The board also does not support refresh rates beyond 2k.

An optional "High-Performance Module for Power Macintosh 6360" that plugged into an internal cache slot was available from Apple authorized resellers that provide a 256 KB L2 CPU cache. Third-party modules in 256k, 512k and 1MB sizes were also sold.
