I have a Mac 128K original, not modified in any way, that I just fixed and is booting up and all. The mouse works with movement but the button will not do anything. I know the mouse is good as I use it on another machine. I have tested the DB9 port, the RC pack is good, and no trace damages found. I see the mouse signal going into pin 14 on the 6522-chip high when not clicked and low when clicked. After this, I am lost not sure where it goes and what happens, but the click will not open anything on the screen. Anyone have any ideas on this and where I can go to solve it?
Thanks
