That got me thinking, since the L2 was nothing more than an embedded Linux system that talked to the L1's via USB, was there such a thing a a software L2? I just got an SGI 1100 off ebay for 29 bucks, bad motherboard But I have a board that will fit. If that could act as an L2 I would rather go that route then have to buy power bricks or hack power supplies together. I know there was an L3 but as far as I know it was just a Linux work station setup to manage the SGI system.
The L3 software includes an L2 emulator (as well as some very nice diagnostic tools). The installation is RPM based, so if you use a different flavor of linux you'll have to adapt and overcome.
The biggest drawback is the L3 package is several years old, and it was my experience that some of the incremental changes to linux in the last couple of years seem to have broken compatibility with the sgi L1/USB kernel module.
The's a few screen shots of the L2 emulator in this thread (the second is a mouse-operated emulation of the L2 touchscreen display usually found in full rack systems), as well as a link for the L3 package: viewtopic.php?f=3&t=16719038&p=7311434&#p7311434
You also might want to take a look a little farther back in the thread at bplaa.yai's method on building the sgi kernel module. I'd have never got it running without his helpful suggestions.
