Hi,
I finally managed to get all the required chips for the MKII. I got the board up and running a few days ago. Everything seems to work properly except for an odd issue with the Keyboard input. Starting with the letter "Q", and every other key after that, the key repeats itself when held down, in bursts, as in it will register several instances of the letter when the key is pressed, has a short pause then continues. This only happens on the QWERTY row of keys. I have tried different Keyboards and CIA chips but the issue persists. I noticed this is first when I was typing some basic commands and was seeing repeated key presses on the screen. This problem will definitely cause grief when Keyboard input is needed. Any ideas of what is happening?
