F stands for Flash that means read/write capability. But 28F is old generation of flash era, they will need +12v on Vpp pin to write. Look on the datasheet for pinout and check the programmer that if +12v is present during write !

it provides 9v only , could I give it 12 vdc to this pin or it will cause problems ?!
