pal gal copy

I think if it's protected, you cannot read back. If not, it was not protected.

cpld copy

Hi weeyndha

Do you know if there is a combinatorical or a register logic inside? A combinatorical can be 'read' out by trying each input combination and to look what comes out. If there are registers used this won't work...

Bye
