Smoke in the Basement (was: SGI IRIS (Motorola) OS wanted)

I'm sorry for the quite long post (for the tiny question in the end), but this again was one of the experiences that made me somewhat doubt my choice of hobbies... ;-( Saturday, May 20, 2006, 2:30:05 AM, I wrote: This week I had the chance to do some more work on the resurrection project. I managed to get some closer look at the boards and their configuration (I'll put the DIP-switch/Jumper settings online for comparison/documentation). I also wanted to get a closer look at the software side so I fired the beast up. Worked like the charm, then started to smell like a pile of burning tyres. Not good. I pulled all plugs and as far as I can see the machine was still operating when shutdown that way. As far as the current inspection goes (pointing my nose at things), it was the PSU that went belly up (what a surprise, it's an SGI after all). It was probably all good luck that I figured out how to boot the installer myself instead of going upstairs(!) to use Google. Anyway... life goes on: Now I need to dismantle the whole beast to get to the PSU and then there is the final question... will I find a replacement if it's FUBAR? Probably I can get an Power Series (IRIS4D) PSU to work - at least these look pretty similar. If I get the pinout right, it shouldn't do much harm if the PSU is stronger I guess (say 1500W instead of 1000W, right?). -- Best regards, Gerhard mailto:mail at g-lenerz.de Old SGI Stuff http://sgistuff.g-lenerz.de/
