The Macintosh Quadra 950 was the third desktop computer in Apple Computer's Quadra line. It was based on Motorola's 68040 microprocessor rather than the 68LC040 (which lacked an on-board FPU). It replaced the Quadra 900, increasing the CPU clock rate from 25 MHz to 33 MHz, and improving the graphics support. The two computers were otherwise identical.
In 1993, the 950 was overtaken in performance by the less expensive Quadra 800 and 840AV. The newer Quadras had the addition of interleaved RAM, as well as an enhanced video system SCSI bus. However, their more compact (minitower) case proved difficult to work with, and the 950 (due to its enormous case) was kept in continued production for the server market, outliving the 800 and 840AV.
The Quadra 950 was discontinued in 1995, being replaced by the more powerful Power Macintosh line of PowerPC computers.
