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. -- Freya Fischer | ffischer@cam.ac.uk PGP Key fingerprint: D96E 03F0 483A E8C4 "Keep the channels open."
