This is a experimental single board processorboard used for DSP in the audio-range. The board contains up to 1 MB rom and 256 KB ram, a VIA with timers and parallel ports, an ACIA for the serial communications and a simple ADC and DAC (ADC0820 resp. DAC0800)
The system runs OS-9 (version 2.3.1). The rom is for a large part arranged as a rom-disk with all kinds of OS-9 utilities stored in it and of course the developed DSP-programs like a FFT audio spectrum analyser, IIR and FIR-filters and some experimental modems for 1k2 AFSK and 4k8 HAPN.
