The Macintosh IIvi (also sold as the Macintosh Performa 600) is a personal computer designed, manufactured, and sold by Apple Computer from September 1992 to February 1993. The IIvi was introduced alongside the Macintosh IIvx (which added an FPU, a RAM cache and had its processor clocked at twice the speed of the IIvi while the data bus was still at the same speed)). The Performa 600 models, meanwhile, are the IIvi with the IIvx's 32 MHz CPU. The IIvi was, on some benchmarks, faster than the IIvx. It is the only model in the Macintosh II family to be branded as a Performa.
This model was discontinued four months after its introduction, when the Centris 650 was introduced at a similar price point.
