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.

General Information

CPU

The 950 uses a full Motorola 68040 processor clocked at 33MHz. The Macintosh Quadra 840av is faster but the 950 was popular for server use.

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.

Notes

  • The Quadra 950 is an ideal server tower for Apple UNIX (A/UX) due to the expansion options.
