Macintosh Centris 650

The Macintosh Centris 650 was a personal computer that was a part Apple Computer's Centris series of Macintosh computers, respectively.

When the Macintosh Centris 650 was introduced on February 10, 1993 alongside the smaller Centris 610, it was intended as the start of the new midrange Centris line of computers, a niche formerly occupied by the Macintosh Quadra 700, which was discontinued on September 15, 1994. The Centris 650 was discontinued on May 15, 1995 and superseded by the Macintosh Quadra 650.

Features
The Centris 650 was based on the case design of the Macintosh IIvx and used the faster Motorola 68040 processor, though entry-level models used the 68LC040 that lacked a built-in floating-point unit. It also introduced memory interleaving that accelerated the Macs overall performance by as much as 30 percent. In order to take avantage of this, both banks of memory need to be filled with matching DIMMS. It supported the addition of a PowerPC upgrade card to its processor direct slot.
