Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise. Requires 4MB ST-RAM and an RGB or VGA monitor. -- === Göran Sánchez === Dept of Electrical Engineering, NETCOM On-Line Communication Services "Tape doesn't lie at 02:14. Ears do."
