| + | The Macintosh Quadra 840AV combines the raw horsepower of a |
| + | 40-megahertz 68040 microprocessor with a 66-megahertz digital signal |
| + | processor (DSP) to achieve outstanding performance. The DSP handles |
| + | telecommunications, speech, and audio functions, allowing the 68040 |
| + | processor to perform other tasks, thereby increasing the total system |
| + | performance. |
| + | |
| + | The exceptional power and built-in features of the Macintosh Quadra |
| + | 840AV let you take full advantage of exciting new audio-visual |
| + | technologies. For example, with its built-in GeoPort |
| + | telecommunications architecture, the Macintosh Quadra 840AV can be |
| + | connected with telephone systems, so you can use your computer as a |
| + | telephone, an answering machine, a fax machine, and an electronic mail |
| + | station. Its video capabilities let you view or capture video from a |
| + | VCR, laser disc, or camcorder in a window. You can also connect |
| + | directly to a TV to show your presentations or to a VCR to make |
| + | videotapes. |

− | The Quadra 840av was the first 68040 Mac to break the 33 MHz barrier. Based on the 40MHz 68040 processor, and housed in a Quadra 800-style case, the 840av included AV features similar to its younger sibling, the [[Macintosh Quadra 660av]]. However, it's AT&T 3210 DSP ran at a faster 66 MHz. It also included one Geoport, and sold for $3,550, which was inexpensive for what was, at the time, the fastest Mac ever. | + | The Quadra 840av was the first 68040 Mac to break the 33 MHz barrier.

| The Macintosh Quadra 840AV and Macintosh Centris 660AV computers include an AT&T DSP3210 32-bit floating-point digital signal processor (DSP). The DSP gives these computers the ability to perform fast, complex real-time data processing tasks, such as speech recognition, audio compression, analog modem signal processing, and so on. In the Macintosh Quadra 840AV, the DSP runs at 66.6667 MHz; in the Macintosh Centris 660AV, it runs at 55.5000 MHz. The DSP chip contains its own 8 KB of internal RAM, which minimizes its use of system memory. | | The Macintosh Quadra 840AV and Macintosh Centris 660AV computers include an AT&T DSP3210 32-bit floating-point digital signal processor (DSP).
