I have a problem with burning sst27sf512 chips.
Does any one have any experiance with burning this chips or how do I set up my willerm pcb45 to burn them. I use to use 29c256 and had no problem.

 

i've got the same board and the same chips. it works fine for me. you have to set the jumper correctly to write them. the software shows you a picture of how the jumpers should look when you select the chip.

Make sure you have it set to pcb3, then select your chip type. It's always a good idea to erase it 2 times first before a burn (sometimes it doesn't erase 100% the first time). Next, open the .bin file you want to burn, and set your offset (hex) to "8000". It will pop up a confirm screen, confirm and burn. If it was a normal SST27sf256 you wouldn't need to use the 8000 hex offset.
