SAM Coupé Disc Protector Unit


The Disk Protector Unit or DPU for short is a small circuit designed to cure corruption of disks whenever the SAM is reset or turned on with a disk in the floppy drive.

The problem is caused when the 8 MHz clock generated by the ASIC is halted during reset, this causes the floppy disk controller to go out of control since it needs the 8 MHz clock all the time.

All that the DPU does is generate a constant 8 MHz clock to replace the ASIC's 8 MHz clock.


Note: you will require basic soldering and track cutting skills to install this modification, if you are uncomfortable doing it then seek assistance.
