Re: Indy case discolouration

retrobrite does NOT work on cases they are not white/beige colored. Yes, I've tried... It has a mottled bleaching effect and causes white streaks. It is VERY noticeable and far worse than having gross dark plastic. There are basically 2 types of UV damage I've observed: 1. Intrinsic oxygen exposure ...

Re: Maintaining Hardware / fesability of keeping hardware running

Basically, Xray doesn't work for high count multilayer boards, espeically ones with flood files or split planes (so, all of them). SGI is notorious for being incredibly lazy with their PCB layout, their approach is just to breakout everything to vias and let the autorouter rip. Which is actually a v...

Re: Octane Dual 400. EMXI Card. Arrived. Problem.

Multilayer board as said before, internal fills are shorting out power and ground together. Should run fine if you can grind off the offending part and file it smooth such that none of the sandwiched layers touch. I have a working dual 400mhz module if you're interested. Module works but its host cp...

Re: Intel backdoor: not a bug, a feature (buy a new processor!!!)

I'll take the security risk, I need compiles to be as fast as possible :D Typical fpga compile is between 3 to 5 minutes for me. I have the fastest singlethreaded proc I can get my hands on (6700k) and not looking forward to seeing times get longer. Guess I can always OC...

Wow many thanks, I tried to find a working archive for a couple weeks and gave up. I'll give it a try. Very much looking forward to have scrolllwheel support in the file explorer.

To be fair, current Intel chips have essentially identical single-thread perf to their predecessors from 3 years ago

Re: What pointless thing are you doing right now?

Still got a lot of work to do, but come a long way. Sorry I can't let the cat out of the bag quite yet but it's card for my octane/tezro. If anyone has experience writing PCI drivers for Irix, I'd be very interested to hear more info. RIght now my plan is to develop a WIn32 driver first. http://retr...

Re: What extremely rare (non-prototype) computers do you wish you could find?

Looking for a Ultra64 GIO board for Indy, but that's pretty much impossible so I will just make my own :D

Re: Murasaki, my Tezro (Quad 700, 8GB)

Tezro has a quite a bit of thermal mass, i.e. it takes at least 10-20minutes of sustained work for it to start increasing, but the fans then do start spooling up faster. They never really slow back down either, since there is so much static consumption :) All fans running full tilt is a scary sound ...

Re: your latest purchase

The bottom picture, the seller is renew_electronics3 and I got one of their Octane2 units as a parts donor. It was quite poorly packed and arrived with the PSU handle completely broken off. Luckily it was otherwise intact (easy-out and new bolts should fix it)

Re: Weird Cherokee PSU noise

Could be the inductors there then. Usually they're varnished in production to prevent ultrasonic vibration which causes squeaking noises in audible frequencies. Over time the coils may break loose and start to move a bit. Coil whine is annoying but doesn't mean anything's wrong. Of course that doesn...

Re: Weird Cherokee PSU noise

Mine made the same noise. I'm pretty sure it's just the PSU fan being pwm'd to a low speed - eventually it would heat up, go faster and go away. If you hook up the fan directly to a 12v supply it's nice and smooth but very loud and will cause a tornado. Strobing harmonics are a tough problem to solv...
