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 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,
