PAL/GAL/PLDs need a special programmer for these devices. 
Youare right there are equations that can be written very easy. 

I been using CAD for schematics now for over 15 years. I have 
seen the software grow and become better. One of the reasons I 
aprticularly do not like Mentor Graphics software from the late 90's  
its to much patterned off of the old CAD 4 systems and software. 

Oly reason why I suggested startt deoce of the ROM at $2000 is if 
the someone like me wants a lot a program space.
