I tried plugging it in but being new to this architecture I don't know how to tell it to look look for the CD ROM. I have 16 of these machines coming. Got 1 to play with at the moment but it won't finish booting. Stops while it looks for an ip from dns server. From what I have been told they used to belong to Wolverhampton university. I figured it would be easier to load a new OS. I decided on Deb as they do an Intel version that I could load onto one of my other machines to get used to how Deb does things. > > Otherwise easy to boot over LAN (needs rarpd and tftpd), although I've not > tried a complete installation like that (needs NFS?). > > Writing as another tyro, I've seen at least one SPARCserver with a > password.

Do you think it might be better to rob the memory out of half the boxes and use in the other half.
