The Macintosh Quadra 650, originally called the Macintosh Centris 650, is a personal computer designed, manufactured and sold by Apple Computer from February 1993 to September 1994. The Centris 650 was introduced alongside the smaller Centris 610 as the replacement for the Macintosh IIci, IIvi and Quadra 700, and it was intended as the start of the new midrange Centris line of computers.[2] Later in 1993, Apple decided to follow an emerging industry trend of naming product families for their target customers -- Quadra for business, LC for education, and Performa for home -- and folded the Centris 650 into the Quadra family.[3]

The Quadra 650 was discontinued without a direct replacement in September 1994, although the recently-introduced Power Macintosh 7100, which has the same IIvx form factor as the 650, had a similar target audience and was sold in the same price range.

Models[edit]

Standard equipment on all Centris 650 models includes onboard video (with VGA support via an adapter), 3 NuBus slots, a Processor Direct Slot, two ADB and two serial ports, and an external SCSI connector. There are four SIMM slots that support 4, 8, 16, and 32 MB SIMMs, allowing for a maximum of 132 or 136 MB of RAM depending on configuration. Ethernet-capable models have an AAUI port. System 7.1 was included as standard and is the minimum required version.[1]
