After having a look at the a590 pictures at The Big Book of Amiga Hardware i think i could fix a broken one unless it's the WD33c93 chip or the 390563 chip that is broken, because i dont know where to get replacements. If the ROM chips are broken i can only fix those if somebody knows where to get the rom contents.
