At 2 am I am not great with my sums. I found what I was looking for with
TI PALS and programing them is not that easy since you need switch between
+5V, 0V, +10.5V and High Impedance ... other than that no problem.
I can use pals but I don't expect them to reduce my logic as much as
I expected since I need 16L8 rather than 16R8 another mistake make
early in the morning after I found some data sheets.
