| The Macintosh Quadra 950 is a [[Motorola 68040]] and [[NuBus]] based tower. This model was released in March 1992 and discontinued in October 1995. This model replaces the [[Macintosh Quadra 900]], and was the last model to feature 6 expansion slots until the [[Power Macintosh 9500]]. | | The Macintosh Quadra 950 is a [[Motorola 68040]] and [[NuBus]] based tower.

| ===Video=== | | ===Video=== |
| The video RAM (VRAM) in the Macintosh Quadra 950 uses 80 ns devices instead of the 100 ns devices used in the [[Macintosh Quadra 900]]. The video controller (DAFB) has been reprogrammed to take advantage of the faster VRAM, speeding up video performance by as much as 20%. That speed increase is in addition to the increase due to the 33 MHz processor speed. The cumulative increase in video performance can be as much as 50% overall. | | The video RAM (VRAM) in the Macintosh Quadra 950 uses 80 ns devices instead of the 100 ns devices used in the [[Macintosh Quadra 900]].
