We are making some progress on this, we are now having the kind of problems that we anticipated in part 2, after looking deeper into the construction. Not least the layout of the board, and the way the board tries to save on decoupling caps is creating some trouble. The way the power lines are laid out is also part of the equation. Although 14.3, 7,15, and 3,5 Mhz is not that high frequencies, they are still so high that there should be some special considerations, especially on the ground plane. So, another lesser step for the Leningrad, but still a step toward a fully working circuit #LeningradClone #SpectrumClone #RetroComputerKIT
