The Macintosh Quadra 950 (also sold with additional software as the Workgroup Server 95) is a personal computer designed, manufactured and sold by Apple Computer from March 1992 to October 1995. It replaced the Quadra 900 that was introduced several months earlier, increasing the CPU clock rate of its 68040 CPU from 25 MHz to 33 MHz, and improving the graphics support.[2] The two computers were otherwise identical, including the price. With a Macintosh Processor Upgrade Card installed, this computer is known as the Power Macintosh 950.

In 1993, the 950 was overtaken in performance by the less expensive Quadra 800 and 840AV. The newer Quadras were faster due to the addition of interleaved RAM, as well as an enhanced video system and SCSI bus, while the 840AV had an even faster 40 MHz 68040. However, their more compact (mini-tower) case offered less expansion capability, so the 950 (due to its mid-tower case allowing 6 slots to be supported) was kept in continued production for the server market, outliving the 800 and 840AV which were replaced after one year of production by PowerPC-based Power Macintosh models. Also, the Quadra 700 and 900/950 were capable of operated 24-bit color with the maximum 2 MB VRAM installed, a feature removed from newer Quadra and Centris models as a cost-saving measure although 24-bit color could be enabled with a video card. [3]

The Quadra 950 was succeeded by the PowerPC-based Power Macintosh 9500 in June 1995, with the 9500 using a taller version of the Quadra 800 case. [4] The Workgroup Server 95 was succeeded by the PowerPC-based Workgroup Server 9150, which retains the same Quadra 900/950 case. Quadra 950 sales continued until October 1995, being the last Macintosh Quadra sold by Apple, and one of the last 68k models to be discontinued, due to its high RAM capacity and large number of NuBus slots.
