Hey, Buddy,
I recently came across one of these myself and hooked it up to my scope. The square wave and triangle wave looks ok, but the sine wave is only rounded on the top side. The bottom is still a triangle. Looking at the partial manual that I have, it looks like D2-D7 make the top curve and D8-D13 make the bottom curve. What's the best way to go about troubleshooting this?
