Nice. I have an SGI Indigo that I will probably never be able to use again because I forgot its login credentials years ago. And I think the monitor was proprietary to SGI and I tossed because it took up too much room.

Then again, I could probably find a downloadable OS for it somewhere online.

Unless it's been secured, you can probably boot using the miniroot on the installation media, go to the password file and clear the root password and save.

Restart that Indigo, and log on as root, no password.

When doing various services on these machines, I would keep a drive ready to boot miniroot. Would clear the root password, archive the hash, then do the work, put it back and on to the next gig. Most of the time nobody even knew what that password was.

Took {big company IT} quite a while to finally call and ask how those services were getting done...

You can definitely boot that SGI in single-user mode or off a bootable OS and read the passwd file. Just found a guide on resetting the root password on an SGI machine[0]. Someone probably would have paid multiple $hundred for that monitor :(
