Iris Indigo - Can't set tod clock

[flexion]

My SGI collection now includes an Indigo

But on power up I immediately get:

"can't set tod clock".

I assume I either have to replace a battery or maybe I have to replace a Dallas Clock chip or something?

Thanks for any advice

I think I have to replace the battery which is located at "BTI".. any ideas where to get a replacement "TL-4986" in europe? or is there an alternative part available? I guess converting to a CR2032 or similar adapter is not possible?

Never had an Indigo but you might check this for the part numbers (as they were in 2009)

Maybe an Indigo owner here can give you more info.

You can get them from ebay still. Needs to be de-soldered and replaced, but it's a easy job.

Thanks!! Good to know the new part number!
I checked ebay and amazon, but since Switzerland is not a member of the EU, most items do not ship to my country. But I have now found a ER22G68 in a swiss online shop! Although rather expensive, as everything here. I hope they will deliver fast!!

An alternative new part is TL-2450/P by Tadiran Batteries i found them for reasonable price on Digi-key 439-1039-ND the leads fit perfectly but it is slightly larger in diameter and does not have the insulator on the bottom like the original so I added a small piece of kapton tape so it didn't short out on the nearby components.
Also of note on my machine I did not even have to desolder as the battery was installed with small through hole sockets that sit flush with the board.
