The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- === Hugo Johansson === Dept of Electrical Engineering, European Laboratory for Particle Physics, Geneva "Hold for relay."

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market.
