Using the Willem Dual Powered Programmer and SST 27SF256

By zCivic

This is the settings in order to erase the 27SF256. Noticed some of the J jumpers on the right have to be swapped. You can not write over the old data. The chip needs to be erased in order to be re-written.

This is the setting to burn the 27SF256, notice the board has to be on PCB3 settings not Willem.
