I have an vintage American Research Corp. 286 (a grate treasure for understanding the hardware part of PC) mobo whith empty DIP sockets for an N82S147 ROM, and 16L8A PALs, in spite of that mobo is a clone of original IBM, i think, that it's schematic is much close, and the PALs from IBM can work in this mobo.Maybe sombody have a reference manual for the IBM AT where the time diagrams of signals is
illustrated.Hopefully it help me to disclouse the structure of PLAs. I haven't any working expirence with PALs, so i very hope that somebody can give me a hint how to read PALs, or can share dumps with me
Best Regards. Vadim
