Re: Model M Requires Hard Key Press on S & F Keys

that's sounds like the black rubber foil has deformed when you putting the keyboard together and it interferes keystrokes. suggest you to take the keyboard apart to make sure parts are put up correctly.

Re: IBM Model F122 Modifications Help

unless your f122 controller has malfunction, I prefer to use soarer converter instead of using xwhatsit. but if you use xwhatsit, better use 3.96mm pitch male and female header for the installation. will show photos on what I did to my model m with xwhatsit and headers.
