Using the same case as the Quadra 800, the 840av incorporates the same AV circuitry as the Centris 660av. Running a 40 MHz CPU, this was Apple’s fastest 68040-based computer ever. The 840av also runs a faster version of the AT&T DSP chip, one clocked at 66 MHz v. 55 MHz in the 660av. This and […]

Initially introduced as the Centris 660av (the two models are identical except for the nameplate), the Quadra 660av shares the same case design as the Centris 610. In addition to a faster 25 MHz 68040 CPU, the 660av includes a 55 MHz AT&T digital signal processor, introduces the GeoPort high speed serial port, has a […]
