You cannot transfer blocks to eprom, you need to blow a new eprom with an eprom blower.
An alternative is to remove the eprom & if your program will fit into on-board ram download it to that.
You wil l need a battery in of course or you will loose the program when switched off, at least this will allow you to try out the new block.
