    There is no way in any practical sense to bypass the security fuse to allow reading the device program.

    You need to either find the original source/program code, or try and reverse engineer the device.

    There are current production devices that can replace the EPM7128E (like the EPM7128S from Intel or the ATF1508ASV from Microchip/Atmel) but you need the source code (best) or program POF file to do it.

Per the Max Loader software (I am using v6.1h on my system) adapter PA84-48F is not the correct one to use for the EPM7128E device. You need adapter PA7128/E-84LC instead. Contact EEtools directly.

PA84-48F:
