Apple Mac Quadra 610

Let’s put it this way, the Quadra 610 was really cutting edge for it’s time. Certainly one of Apple’s greatest computers for the time. The case in itself is evocative of Apple’s hey day, long before the Company started to produce the iconic products we all know today. The Apple Macintosh Quadra 610 (PC) features a 25 MHz 68040 processor, 8 MB of RAM, and a 160 MB or 230 MB hard drive in a compact desktop case. The Quadra 610 PC-Compatible shipped with a 25 MHz Intel 486SX processor card that can have a maximum of 32 MB of RAM dedicated to the DOS/Windows operating system. The workgroup server version of the Macintosh Quadra 610 is the WGS 60.

The Macintosh Quadra 610 and Macintosh Centris 610 are two closely-related personal computers 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.

Notes: 1.
Early models came with a 68LC040 processor and no
FPU.

2. This model is
sometimes designated as having a 50 MHz processor,

since
the clock input runs at 50 MHz. However, the processor
itself

is
not “clock doubled”, so technically it is only a 25 MHz
processor.

3. Third-party
upgrades and accelerators are available.

4.
512k is soldered, expandable to 1 MB with two 256k
SIMMs.

5.
7″ NuBus slot occupied by PC-Compatibility card in PC

One external 5.25″ bay is available if CD-ROM is not
installed.
