While doing some floppy drive servicing i might as well show them off. Build in february 1982 these drives (and the computer) are older then i am myself.
Turns out they just needed a drop of oil and a gentle cleanup.
Since my Osborne 1 is unmoddifed i can only read single density floppies which means i only get 92kb of free space on a formated disk.
While the drive itself is a fairly standard full height 5,25” disk drive, the PCB that drives it is custom made for the Osborne 1 machines.
