Hello, I'm just finished recapping my old Macintosh Classic II and now toward fixing the internal floppy.
The internal floppy would boot into a happy mac logo but then eject the floppy.
But this would not happen when I'm using the same floppy but used as external floppy (using cable from DB19)
Voltage is stable around 12.05v and 5.04v.
Already changed the ribbon cable and tried to disable some pins related to red/yellow stripes issue.
Already tested for continuity from the ribbon connector to the SWIM chip and to the DB19 connector and no issue.
From the schematics, the difference between the internal floppy connector and db19 is the bourne filter (RC3) and no issue from the continuity test.
Anyone can recommend me any solution to this issue?
