Re: 2 x MIA Connectors required FC

ordered one, (yellow) Hmmmm, yellow is often single mode fibre. You need multi mode and those are usually orange. Other keywords to llok for: "50/125 µm" and "62.5/125 µm" are multi mode, "9/125 µm" is single mode. Single mode is for long distances (kilometers) and req...

Re: 2 x MIA Connectors required FC

I have some Fiber Channel cables I'm not using but I don't know if shipment from the US to the UK would make them worth it Thanks, these cables are really long, and long for a good reason, the A5000 is terribly noisy. Tell me about it, my A5000 left the building :) How long is really long, because ...

Re: Indigo 2 video output to vga monitor?

that would also imply that the first two cases of (3) could be combined, if you don't use pin 3 of the 13W3 connector. I believe the DDC connection is one direction, monitor to system, and so is the function of the 4 monitor ID pins. As far as the cable/adapter goes this should be irrelevant. An ol...

No, the R10K much faster. At the same clock rate, the R10K is roughly twice as fast at integer operations, and up to 5x at floating point.

The details are buried somewhere on Ian Mapleson's site.

Re: Indigo 2 video output to vga monitor?

I have an old-ish dell monitor that I'm guessing doesn't have sync on green support. First of all: you might be in luck here. Several do support SOG. In general, there are three scenarios when it comes to sync on green: ⋅  The monitor supports SOG. If the monitor has a VGA input you only ...

Re: WTB-Indigo2 Stuff

All I know is that the graphics board causes the hard disk to not work, as it spins up when the graphics board isn't installed. That tells me at the very least that I need a different graphics board. Could be power supply related, combined load of graphics and disk too much for a PSU on it's way ou...

Re: Does anybody use REV disks?

It's like the Iomega Jazz etc, removable disks of something like 30GB. We had one as a server backup way back when that server was a Pentium III, I still have the device and a stack of disks somewhere but never used it. I think they stopped selling disks for it more than 5 years ago so to move to th...

I recognize the LH Research power supplies in that Convex. I have more or less the same in my Professional IRIS.

Re: Was this PCI-X card used in SGI Flame/Smoke systems ?

SGI jumped the shark when it dropped MIPS, just say no to all things SGI on Intel/Linux... ;) I chose to limit myself to their MIPS/IRIX range. You've got to draw the line somewhere if you don't want to become the computer equivalent of the crazy cat lady, and this is where I drew my line. I might ...

Re: your latest purchase

FireWire also had direct access to memory, sparing precious CPU cycles when doing lots of operations over the bus. I have tons of FireWire devices, and so far I haven't had the need to upgrade. DMA from an external device? Sounds like a bit of a security risk, unless I'm misunderstanding something....

Re: your latest purchase

USB2 came out and sort of obsoleted it. Sort of, yes. On paper the 480Mbit speed of USB 2.0 should have blown FW400 away but most mass-storage devices still had better throughput with FW400 The 480Mbit number for USB2 is raw wire transfer rate, after you deduct 8b/10b encoding you're left with 400M...

Re: Monitor Calibration and IRIX?

Sorted out the calibration of the LCD2690WUXi2. I have a PC with an Nvidia card running Windows 10, and it's normally attached to a NEC EA275WMi screen. It can detect this screen for what it is, and it all works fine, except the SpectraView software cannot communicate with it. Not using the DVI conn...

Re: your latest purchase

Got myself a Wacom Intuos2. A big one, XD-1212-R, with accessories like a 4D mouse and pen. All of that for the lovely low price of 25 bucks. Then I got tired of toying with the Wacom control panel and decided to load Flame on my Octane2 to see some real action. That *completely* FUBAR-ed the IRIX s...
