A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Dave Kim Tape trading list upon request. SASE required for international mail.

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- Göran Smirnov -- Public Access Unix of New York "5 sigma is a discovery. 7 is a question."
