Sun ultrasparc processor boards

Postby Slive » July 13th, 2018, 7:42 am

Hey,

I also got 8 of these nice little boards. Would you say it's worth it to remove the CPU and sell everything separately ?

Also please check the BGA Type module I "opened" :twisted:

Thanks

the real question is what type of interposer was there? do you still have it?

The die came off with the heat sink. The interposer is still on the board I guess :?:

no, the interposer between the sparc CPU and the board... if it is black, keep it, if its translucent amber, its not worth much

LOL!!! My exact same thought when I see them. When something can yield up to 50%, you mind it!

Got it. It was translucent amber and I still have it. So no point putting these on ebay or something? I guess, I can sell the CPUs for ~6€ each.

Thanks! :D

Sell the CPU:s to a collector, there's not a lot of gold in those.

The majority of the gold in those boards is in the nine plastic BGA chips left on the board. The fingers are easy picking too but probably less gold than in the BGA chips.

Date-wise I would guess around 2001, so all the MLCC:s might contain palladium and silver. No guarantee though.
