That's good news. Now if he only would send back my PLA chips ;)
BTW, because Jens told me that he does not yet have replacement PLAs for the
8296, I decided to put Andre's equations into a GAL and make an adaptor
socket for it. It works nicely, but only the "small" 82S100 PLA can be
replaced with a GAL and some tricks are needed (feedback) to squeeze it in.
Since only the small PLA was broken in my board this was fine for me.
