Help with willem programmer
 

ok, im having some real problems using this, i have a few bin files (which have all worked for a friend off mine) the chip is a 27c256 so i set the switch's the right way, when i try to write the chip it said something about buffer at 00x08 and device at 00x00, after searching the internet endlessly i found that i needed to set the offset to 006000, this is so it writes the information in the correct place, so i do this, but when i check in the buffer the information does not start at 006000 like its ment to.

I have no idea what im doing wrong and its making my head hurt! also why does it point a big arrow at icsp? am i ment to do something with that? and ive seen people talk about a 'jumper switch' whats that? thanks! heres a pic, maybe someone can see what im doing wrong?

I use the sst27sf512 that I use, but the offset for that is 8000 which works, I don't know if that offset will work for your chip, but it might help.

If you click on the pcb3 it will switch it over to the Willem setting, then set your dip switches. The jumper setting depend on the chip your using. My guess is that you'll have to leave them in the default settings. Push the middle button in the middle and it will put leds in the default positions. There is a jumper next to the lever that you need to remove to write to the chip.

Hope that helps
