Sun 1/100U ... it LIVES!

My Sun 1/100U lives once again... reseated the boards and realized someone had removed the ram board. I just happen to have ram boards that came from a sun 2 server, and poof! It lives! The monitor is in pretty good shape, the image is shifted a bit, but it looks like its mostly if not all visible. The main problems are: I have no idea how to enter the local prom mode, or even if there is a local prom mode.. Whups! Looks liek one way is to let the computer time out on its boot attempt. I still cant get any help on available prom commands. 'printenv' printed a small hex-dump like thing, then immediately the screen cleared and rebooted... Anyways, main problem is going to be locating the OS for this computer. Does anyone have SUN OS for a Sun 2 class computer? I forget what its called, suntools or sunview or something like that.. -Lawrence LeMay
