Re: Rack mounting SGI Origin

The power button is 20 years old and with a bit of silicon oil it will work just fine.

Re: Crimson thermal trip at boot

My Crimson does this too, and it has the PowerOne PSU. It powers up fine, but after a couple of minutes it triggers the thermal switch next to the front panel power switch. IIRC, there are two inputs to this protection circuit, one from the PSU, and one from a sensor located above the card cage. Tha...

Re: Octane 2 Hardware schematics and assembly drawings sought I a Searching for Octane2 Hardware schematicsandassembly

What I am starting to worry about with the age of the SGI gear are things like PROMs decaying, whether single (E)PROM chips or inside other things like PLDs. Supposedly they have a ~20 yr lifetime from when written. That's why I've made backup copies of them. That includes GE boards of GTX or VGX g...

Re: Octane MXI board TRAM problem - any fix, or is my TRAM toast?

It looks like one of your TRAMs is faulty, resulting in the interleaved pattern. I would run the IDE diagnostics from the PROM menu, from a serial console if you can. See if it narrows down the problem to one of the two modules. Leave the other one alone, because whatever you do can only hurt it. I'...

Re: Rising NeXTStation prices

In general, I have the feeling that prices are slowly rising. It used to be you get an Indy, Indigo2 or Indigo for $0 ... $50. I still frown when people ask $200 for an Indy because I'm so used to them costing ~ $25. I pulled PowerSeries desksides out of garages for $25. But those were all systems t...

Re: Hardware partitioning on O200

If I'm not mistaken, the O2K series can be partitioned at the module level. Every module needs base IO. For an O2000, a module is basically an O2K deskside. For an O200, a module would probably be ... an O200. And, this being an O200, two modules would be the minimum (duh) but also the maximum confi...

Re: Why can't we sell/trade original commercial software?

IRIX is a bit in between. Too old to be useful in a professional setting, but new enough that many of the applications are still actively maintained on other platforms. Which means I cannot buy the IRIX application because the vendor isn't willing to sell / support it (probably a valid business deci...

Re: Stripping six O200: what should i keep?

If you find an IP29 mainboard rev 030-1389-00x in there I'd be interested. These are more commonly found with R12K CPUs. Mine has probably had a CPU upgrade at some point, because it has the R12K CPU, but the 030-1244-001 mainboard. Then again, flashing CPU speeds in an O200 is apparently risky busi...
