Hi, I have to replace a memory in an equipment that I didn't make. I obtained a file from the manufacturer to burn into a ST27C64A which looks like this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he person that sent that to me, says it is Motorola S19 or S16, don't remember, but I cant find a way to successfully save that file to the memory and read the correct checksum that he says I must read... Any ideas?
