+ | Assembled the second DigitalController and wrote code for RAM simulation. It seems to work fine! Found that some more input pins would be of more value then output pins. But that is hackable. https:// | ||

+ | After I found that the ISP programming pins are wrong, I successfully programmed the first digital controller. The clock simulation is now up and running. Next RAM and ROM simulation. That will be a software task. It is fun to work digital again! | ||
