If anything, I'm getting proficient at disassembling and reassembling a Macintosh SE.

Following the wiki instructions, I cleaned and lubricated the floppy drive then with the it appearing to be in good working order optimistically put everything back together . . . And it still won't read the floppy disk and it still cannot eject the disk. Had to resort to a paper clip to eject the floppy.

It may be time to declare it dead.
