Unfortunately, the RM-64 fails irsaudit. It doesn't seem to result in visible artifacts, though.

Here's what I had to do to get this far:

* The IO4 board had a Dallas with an empty battery. This makes the machine forget it's configuration and it causes IRIX to print a continuous stream of warning messages on the console -- not very handy. I replaced the entire IO4 for the time being.

* The machine was password protected, and it's security policy was rather strict. Futile once I get physical access, of course :twisted:

* The RM6 was in the wrong slot (RM2 slot rather than RM0 slot). Graphics doesn't work like that.

* The InfiniteReality FP1 front plate had been engaged rather cruelly which had damaged the connectors on DG4 and RM6. It had also crushed a handful of wires on the back side into a solid mess. I undid that, but it seems the RM6 is toast anyway. In fact, I think someone 'borrowed' an RM from this system to fix up another Onyx, and left this one in a mess.

* The GE12-4 would make 'irsaudit' crash. Fortunately, after a fresh IRIX install, GE flash and clearing the IR-EEPROM that solved itself :oops:

* All SCSI on this box is high voltage differential. I had to mod it to attach a CDROM.

* Two out of five original harddisks were dead. Bummer, but all these 2GB and 4GB disks don't add up to much anyway.

Tasks left:

* I'm going to mod the IO4 with a CR2032 coin cell holder to solve the Dallas problem once and for all. Pics will follow.

* The system controller is giving me a handful of '???' when powering down. Might be another dead Dallas. This type is still available, but I think I'll mod it anyway. I'm tired of these things.

* The hinge of the front door broke, it has been repaired but in such a way that it doesn't close anymore. I'll have to fix that.

* The system was loaded with Alias|Wavefront, ProEngineer, etc. I'll have to see if there are any licenses and other interesting bits left.

* Upgrades?

Bah, even with a professional desoldering station it seems to be impossible to remove a Dallas from an IO4. I'm going to have to think of a plan B

-smirks- Ah it found you

Yeah the Dallas clock chip is a real nightmare. I can't understand why the heck they didn't simply put a coin battery holder on the board...
Seriously -.- Anyhow I believe this has been discussed in some detail and there are quite a few examples of individuals who were 'brave' enough to resort to hack and slash butchery...

heat gun + tin foil + braid? soldering iron? pentium did a how-to a few years ago:

Maybe he will chime in with how he got it off... or maybe he did the mod with the chip still on the board?

If you are referring to that one photograph where I am checking the voltage of a dallas chip on an IO4 I never really removed the dallas chip from the system. I simply shined a bright light against the side of the chip, looking for the two spots on the chip that's missing pins. and then very carefully used a dremel to clear away the plastic and resin that covered the bettery leads.
The other dallas chips seen in those photographs were all from socketed PS/2 systems but are essentially the same.

I've tried it all. Even tried a professional desoldering station. It won't give in. I'm not going to push it too far and burn the PCB.

I've seen pentium's work:

I've reworked a Dallas before. This is the result (from a SUN SparcClassic):

Find the differences :lol:

Usually Dallas chips are socketed. This one isn't. Since I cannot remove it from the PCB, I'll have to rework it while it's still installed. That, in turn, means the support next to it will have to be removed.

I intend to use an SMD style CR20232 holder again like I did with the SparcClassic. There's room for one on the IO4 next to the Dallas, putting it on top of the Dallas might cause problems with IO4 mezz cards.

Replacing IP19 with IP25 and maybe do some benchmarks.
