Re: Onyx N64 hardware

They needed a workstation to develop the characters and scenes with, it's not about emulation.
Programs like Mirai and Softimage had features for optimizing 3D models for both the PSX and N64 and converting to their native formats.

Re: [ebay]: Indigo2 R4K Galileo System

very possibly so. On Indigo and Indy there really are three slots, one is dedicated to gfx.

Re: SGI O2 PSU pinouts

5.10V and 3.40V are the rated voltages on the label of the power supply. If they are much different under load that would mean quite poor load regulation. The supply uses cermet feedback trimmers, that seem to be factory adjusted very close to the spec. The O2 uses 5V PCI signalling and most of the ...

Re: [ebay]: Indigo2 R4K Galileo System

I also wonder whether the limit on GIO64 devices is really 2, since all the technical documentation and irix.sm comments say there are three logical GIO slots.

Re: [ebay]: Indigo2 R4K Galileo System

Thanks for the link to a picture of the Ciprico card, I hadn't seen it before. It confirms my hunch that all Ciprico's products were Qlogic based. That strengthens the probability that the picture in the auction is of an Adaptec EISA card, now I just wonder where are the drivers :) The cable between...

Re: Power down the drives?

You can experiment using scsicontrol -H to spin down drives manually. I don't necessarily endorse this, the system may try to flush some pages to disk, hit an error condition, and panic. Automatic spindown after a period of time is a feature found on (S)ATA drives. There is a SCSI mode for it (Stand...

Re: Raspberry Pi - Anyone been following these?

If hardware hackers take a liking to it (as with the Arduino) it won't be long before boards are available that piggyback on those GPIOs to provide relays, motor controllers, ADC, etc.

Re: SGI Super Disk Question

There was also a parallel-connected floppy drive mentioned in SGI's O2 User Manual. I've never seen one. What was its capacity?

Re: DM3 / DM5 LVDS cable pinout

recondas, in the two PDFs you linked, the 3M one and the CameraLink one, the "pinouts" or connectivity between the plugs is the same. Both are simple rollover configurations (which is actually a simpler configuration than "straight thru" for connectors with multiple rows). But th...

Re: Trouble with a 3C597 NIC

OK, I installed this several years ago, so I don't remember all the details of how I set it up. But I can check config files to see what's there now. In /etc/config/netif.options, I have if1name=ec0 if1addr=$HOSTNAME if2name=fe0 if2addr=anothername you can also use gate-$HOSTNAME as the address of t...

Re: [ebay]: Indigo2 R4K Galileo System

the AHA174x had both the legacy AHA-1542 ISA controller and a new EISA controller (that predated the AIC7770). It could be used with either one controlling the card. Perhaps there was a GIO64-PCI bridge on card, or perhaps the seller misremembers.

Re: Trouble with a 3C597 NIC

Non-IMPACT backplane has 4 EISA slots so you should be able to fit it in the top or bottom slot. There is no problem I know of with R4K machines, I use one with a 3c597.

I can tell you how it's setup later today, but I suspect the netif defaults may not be quite right.

Re: [ebay]: Indigo2 R4K Galileo System

Actually it looks like XZ or Elan GFX. See on the back panel the Genlock SMB (mini-coax) port. XL does not have that. I've heard of the Ciprico GIO64 SCSI boards, but never seen one. On http://www.futuretech.blinkenlights.nl/i2info.html it says there was an EISA SCSI option, but performance I expect...

Re: Raspberry Pi - Anyone been following these?

"GPIO" is a software-controlled port in which every voltage transition on the wire requires an instruction. You would be lucky to get 1 Mbit/s for any purpose.
