The Macintosh Quadra 610 and Macintosh Centris 610 are two closely related personal computer
s that are a part of Apple Computer
's Quadra
and Centris
series of Macintosh computers, respectively. When the Centris 610 was introduced in February 1993 alongside the larger Centris 650
, it was intended as the start of the new midrange Centris line of computers. However, that proved confusing, and the Centris 610 was renamed to Quadra 610 in October 1993, and the CPU was upgraded from a 20 MHz 68LC040 to a full 68040
at 25 MHz - although there was one configuration, the Quadra 610 8/160, that retained the 68LC040. The Quadra 610 was discontinued in favor of the Quadra 630
in July 1994.
The 610 came in a new "pizza box
" case that was later also used for the Centris / Quadra 660AV
and the Power Macintosh 6100
. The Quadra 610 was also available in a "DOS
compatible" model with an additional 486SX processor at 25 MHz on a Processor Direct Slot
card.
