I've been able to confirm through a couple of Internet sources that DCO2 on the Poly-61 (the 800's predecessor) is a purely digital oscillator, rather than an analog oscillator under digital control, like DCO1. One article I found said that DCO2 on the 61 "is just a 4 bit binary counter with some resistors on the outputs forming a very simple and cheap digital-to-analog converter."
Is the same true of the 800? Can anyone confirm?
Thanks!
