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.
