Can someone school me on PALs and GALs?

yeah, I'm using WinCUPL as that's what everyone has recommended up to this point but I get the impression that it does "minimization" as part of the compile routine. Maybe I'm missing something but I don't see any options to minimize the equations directly. If I try to compile with the giant equations it tells me they're too large and can't be compiled.
I haven't tried ISPLever Classic, but Logic Friday seems to be no longer officially available and I haven't been able to track it down.

You're right WinCUPL does the minimisation as part of the compile. So does ISPLever, I think. However ISPLever is much more powerful and might be able to have your equations fit.

Guys ,here are the gerbers for Charles MacDonald Pal Adapter if you need to print on oshpark or other pcb manufactor. But i'll be happy if mr. @brizzo can give his much nicer board who use a zif socket instead a 20 pin socket . in any rate, a TL866 II pro are on the way from China to me and i can be chilled when i need to write a pal/gal chip

ps : maybe this programmer can be a good way too.
