Re: [NTLK] [OT]: dead SE FDHD (was:my old Mac SE20~help!)

The early models were definitely soldered in, the later models were
not. I will update that portion of The Mac 512. I would look on the
back of the SE and find a door with a tab you can remove. Behind that
door should be the battery.

I would say no because the SE boots up and tries that disk, then spits
out the disk. I think your battery is fine.

Usually if a Mac SE cannot boot off of a floppy disk either the disk
went bad or the SE does not think you have a valid System Folder and
the disk is fine. What System are you booting with? Do you have
another Mac (with a floppy drive) to create a new boot disk?
