Built the single step circuit and followed these step and checked /IRQ if it was high all the time. Well it wasn't. It went low after step 6 but the SEI instruction had then been executed so an interrupt could not happen...I read CRA (to reset the FLAG) in the beginning of the initialisation of the RTC...it worked.
Nine times out of ten, it's defective code that gets you. However, you now have tools to take care of that tenth time, should it arise. :D
x86?  We ain't got no x86.  We don't NEED no stinking x86!
