Help with Password Security on PowerBook 1400c
I recently acquired this PowerBook 1400c, which powered right up and works, but requests a password. I've done quite a bit of research about this, and it seems like it's something on the hard drive that can be defeated in a couple ways. One of the ways is to use Norton Disk Editor, but it seems like it would require booting the machine from another drive (like a CF card) or connecting the drive externally to another old Mac.
I found one other post here:
https://arstechnica.com/civis/threads/help-needed-unlocking-a-very-old-mac.264444/#post-6107934
which describes another method which seems much easier. Holding the option key and clicking cancel does indeed generate a code. However, the post vaguely describes using a "Classic only application" to acquire the unlock code, but I cannot for the life of me find out what this application actually is, or where to get it. I imagine I could easily use this in SheepShaver or Basilisk, if only I knew what it was and could get a hold of it.
Does anyone have any idea what the aforementioned application is? I'd really like to get this 1400c working. To add, I already tried guessing hundreds of times, starting with "Kramer", so I'm really losing hope for brute forcing the password. Thanks in advance for any help!
