Description: Small programs allow copy entire RAM image in to programmable fiscal memory 27C512/also cleaned Winbond W27c512 supported and restore RAM image from it.
i wrote this code easyway to fix some ram errors
schematics of cashregister included , but it version is 2102 , the 3102 hardware is very simular to it .-Small programs allow copy entire RAM image in to programmable fiscal memory 27C512/also cleaned Winbond W27c512 supported and restore RAM image from it.
