You do not have a working GAL or your circuitry. Solve this issue

Further it will be even more difficult. GAL timing will not match the IDE.

Well, the problem was eeprom chip (addition to that faulty GAL chip). It did not work with SST39SF010A chip, but it shuold have worked?. I have tried two that kind of chips, and both did not work. I could program and read those with Willem programmer, so the chips are not faulty.
Now when I received AM29F010 chips, idefload could program then eeprom and after reboot the sunrise was working. I had to manually give slot number for idefload (so autodetection did not work).
