Recently I acquired a matching floppy disk station for my Commodore PET 3016. It is the CBM 8050, a single sided, dual disk drive using quad density floppies with 96 tracks per inch. This is a rather rare format, but with a bit of luck we should be able to use high quality double density (48 tpi) disks instead. But first problem is: The drive can’t even format a single disk. It is probably not a surprise as this particular device was manufactured in 1983. First order of business is to take it apart and do some diagnostics and cleaning!
