From the project
The 8" floppy drive power suplly can be used to power 8-inch floppy disk drives (using a suitable cable).
Some drives required a direct mains AC line connection. Make sure that your drive model is compatible with your mains AC voltage!
_Important: Connecting the wrong mains AC voltage to your drive will destoy it!_
You can search for the right AC and DC cable in the list of drives and/or the list of cables below.
WARNING! RISK OF ELECTRIC SHOCK! Power cable must be unplugged prior to opening the fuse holder!
