Commodore SFD-1001 Repair

Another dead floppy drive has landed on my desk. I was told that "the motor isn't working". That can have different causes, but let's find out what the actual problem is. I never worked on one of these drives before, but they are related to the CBM 8050, a drive that I like very much. Join me on Mastodon: https://chaos.social/@root42 Music: A Little Wonder by Spino2006
