I've built an atfblaster/afterburner that can now program my ATF22V10 chips. WinCUPL is not the most expressive software when trying to understand what is wrong in the source, but it works under wine/linux.

My main problem now is that I created a test setup with a Pico and the 22V10 to test the function, but I can't seem to get anything to work. More debugging and trial/error to go.
