personal computer by Apple

Apple replaced the Quadra 900 with the 950, boosting CPU speed from 25 MHz to 33 MHz. Because Apple removed some “wait states” from the video section, the 950’s internal video is about 20% faster than the 900’s – and the faster CPU helps things along even more. The 950 can display 16-bit video on a 19″ monitor without the need for a third-party video card.

The Quadra 950 is built like a tank and obviously designed to sit on the floor. With 16 SIMM slots, you can add incredible amounts of memory, along with plenty of huge hard drives. This is obviously designed to be used as a server.

According to Apple, the monstrous power supply can support two 25-watt NuBus cards and three of the more typical 15-watt cards.
