How can I backup it?
I swaped the ROM (U12) to the other Board in the Same position as bevore.
The Original PCB is now on the disk but it makes now the same sounds. It sounds like Spinup for 3 Times and shut down. |

| So you'll need a 1692 PCB and switch the U12 chip, then figure out a way to decrypt the clone (assuming it is encrypted, most are) |

You'd have to transfer the U12 ROM chip (if it has one) to make it actually work. If you're just looking to get data back off of it, you're better off just temporarily gluing ... |
