Mac G3 password hacking?

I got a second-hand mac G3 for Christmas, from the sysadmin at my dad's office. Unfortunately, the sysadmin neglected to remove his accounts (and passwords), so as of yet it's impossible to get past the boot screen. Does anyone have any ideas about how I may crack the password or hack into the account... (changing the root password in single user mode doesn't work...) Oh, and by the way, it's running OS X of some sort, but since we can't log in, it's hard to know what cat it is.

Help please!

UPDATE:
With the help of this site, we made an administrator account. We still don't know the master password, and there are a few untouchable files, but we can basically do whatever we want. The next challenge is to connect it to the internet...

If you want to know how we got in, here's what we did:

(1) we held down command (the propeller) and S as it booted --> this opened single-user mode, a command-line interface with root priveleges
(2) instead of "rm"ing (removing), like the web site suggested, we "mv"ed (moved) /var/db/.AppleSetupDone to /var/db/.AppleSetupDone.old
(3) we rebooted, and followed the instructions on the screen

What did this do? It moved the file that told the computer that the computer was set up, so the computer ran the setup "wizard" like it was the first time the computer had ever been booted. After that, all we had to do was follow the instructions on the screen to set up an administrator (root) account.

We also learned that the cat is panther, so we might be updating it to a newer version.

Thanks for the help!

Thanks. Got a used G3 for my daughter at a silent auction and couldn't log on. This helped more than you will know.

You did great

I had the same problem as you, only had to login to mac os 9. Turns out my mac was dual-boot (os 9/os x 10.2.8) so i booted into the latter and removed the multiple users file for os 9. Worked a treat after that.

That's one way to get around password protection with a dualboot mac.

You’ll notice there is a login screen, and you dont know the password! This image was created by “deadmoo” and we can easily change his password. Reboot the machine again. Again, hit a button at the darwin screen. This time type “-v” and hit enter. At the command prompt screen type:

sh /bin/sh
passwd curtis
(change the password to what you like)

passwd deadmoo
(change the passwrod to what you like)

Done! Now reboot once more, and again use the “-x” option. Everything should boot, and at the login screen enter your new password.

sorry, can't have any mistakes, and those characters won't help:

Hm. Tried that on a newly broken mac, but it prompted for the old password, rendering this redundant.

. Call the sysadmin and ask him. There may be some nice software installed that you don't want to lose. . If you can't get ahold of him, it'd probably be best just to go ahead and reformat the HDD, then reinstall your OS. This will get rid of any junk left behind and give you a fresh start.

I would reinstall the OS, but I don't have a disk... Thanks for the help though.
Oh, and by the way... the only "nice software" it has is python. Everything else is old versions of standard mac stuff... iTunes, for example, is old enough that it can't read my new iPod. (Although that might have something to do with the fact that it's windows formatted...)
