OK Completed the SIO board today! Like the above comment, this is really a great Z80 machine. Here is the finished board as well as the 1st listing entering into C/PM enclosed. So cool to see that classic C/PM operating system and MBasic as well.

Still have this issue tho with not only having to slide the Top keypad board half way onto the CPU board, I even have to slide the SIO half way as well. idk whats happening because it works fine with all functions but if they are "squeezed" together for a tight fit, no led display or even now sio access is possible. I have to look into this more but halfway works for the time being and I am having fun. Even checked out the SD card and Xmodems stuff and everything works great!
