The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus. 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. -- Nadine Park Tape trading list upon request. SASE required for international mail.
