Size does not matter on these. I've used PCB's from 80Gb models to work perfectly on 160Gb models.

If the original PCB did not have a ROM at U401, then any PCB without ROM from same family will work.

If original has ROM, then u need board with ROM and move original ROM across.

Hi,

there is a fusible resistor on calypso III boards that usualy burns when the motor controller fails. It is located besides R504, but a smaller one.
U should also check Q500, this is often shorted when the L7250 burns, and if so, the new one will be gone soon.

regards,
