Burning SST27SF512 chips with Dollar store burner - help!
 

I'm trying to burn a SST27SF512 chip with my cheapo Willem Eprom burner with no luck.
I have no problem with the AT29C256 chips though...

I have this bruner:

...and I am unsure as to what settings I need on the burner (as it came with VERY little instructional material).
Anyone have any experience with this shitbox burner?

You need to have your offset set at 8000 to burn that particular chip.

Also, you have to erase it every time before you burn a new bin onto it again. Which means you have to change a jumper, erase the chip, change the jumper back, burn the bin onto the chip.

How exactly do I "set my offset to 8000?

...and which jumper am I removing/installing and when do I remove it, and when do I install it?
