Fuel snaphat replacement

Unread postby cascatino » Mon Jan 29, 2018 10:25 am

Hi there, I'm Matteo an all new sgi fuel owner, my knowledge about the sgi world is only the myth that precedes every workstation, my Irix knowledge is poor, but with great possibilities of improvement. ;)
I promise in the next days I'll post the hinv of my machine but, first of all, I have to solve some issue regarding my machine.
This computer has been inside a garage for almost ten years, it powers up and so on but it shows a series of problems I have to face one at a time.
The first issue I have to face is the real time clock message about a "preposterous time" and a kernel time put in the future (I think the date sets itself in 1998).
After reading some precious topics inside this treasure island I decided to adopt the less expensive solution: replace the yellow snaphat battery. I hope this could resolve at least one of the issues I have to face.

So today I received a new snaphat (for about 8$) and I started opening the red belly of the workstation.
Before I do something orrible I ask you: do I have to simply pull out the old snaphat or do I have to unsolder it or something like that?

In other terms: can you tell me how to replace the snaèhat without causing other problems to my fuel?

I hope my english in understandable...THANK YOU!

It just pops out, but can be a pain to remove. If you're struggling, buy an IC extractor tool - it will make removing easier.

Note that there's also a black Dallas battery too. These are now difficult to find as they're out of production. But, replace the yellow timekeeper first and see what this fixes.

Thank you Trippynet!
I fear I have to replace the Dallas one too, but hope is hard to die!
:-)
Tomorrow I'll buy the IC extractor tool and proceed with the replacement.

Done the replacement.
Set the date.
Tomorrow I'll see if there's an improvement.

Hello there, just for the sake of knowledge: the fuel doesn't seem to have any date issue, now.
