Sorry to hear you're having problems vvuk, but I think jan-jaap has given some excellent advice (as usual). Hope you're able to get it up and running, it's a great system and I glad the person you got it from found someone who'd appreciate it.

If you're curious, the chassis of that g-brick started life as part of of O2k based Reality Monster at a University in North Carolina. I purchased two graphics modules still mounted in a single O2k rack from a dairy farmer who acquired the entire Reality Monster as surplus to resell on eBay. By the time I got there all of the graphics boards were already gone, so both graphics modules were empty other than the power supplies, MSC's and IO6Gs.

I started by adding a single IR2E board set to one of the graphics modules and connected an 8x200 O2k. Ran it like that for some time and slowly morphed it into a IR3 system. Along the way I discovered that the chassis of an O2k graphics module and that of an O3k G-Brick are the same. The O3k L1 controller attaches to the same system board interface as the MSC in the O2k-era module; once that's in replace the Cray-link based K-Town interface with a NUMA-link compatible K-Town-2 and trade the purple plastic skins for the blue metal o3k style fascia. The hardest part (for me) was obtaining the pinout for the serial-to-USB cable that connects the L1 in the G-Brick to the L2 controller. When all that was finally done I initially ran the now re-minted G-Brick with a 16P O300, and later replaced that with a quad 800 O350.
