Two other cpu saved from gold-scrappers

[andamus]

Hi,
today I've received two other IBM MCM, saved from gold-scrappers, sad they both have suffered heavy damages.
First one should be some kind of Power 4 (the pins are divided into 4 squared arrays) while second one it's an IBM Muskie cpu

damaged but still impressive

[andamus]

Yes,
the first MCM it's really huge,it's bigger than the other IBM MCM I already have, check this photo to get it's real dimension

andamus,

I'm really glad you got these. I saw these but forgot to bid on them.

Eye-candy chips! It's quite difficult to identify because there are some missing dies (or not). If you're brave, you can count the total pin number and check here:

Hope this will help.

How old are those IBM modules and what were they used in?

Are they military?

[CPUShack]

They are CPU's used in mainframes.
Not really military

Hello andamus,
very nice MCMs, damaged but still a technological wonder.
The first one is too big to be a POWER 4, I have a POWER 4 CPU board and the MCM is roughly equivalent in size to a Socket 7 processor.
I guess it's a CPU from a IBM S/390.

P.S. andamus, se abiti vicino a Udine... MANDI!!!

S/390 G-Series MCM imho.

Hi,
the large MCM has 3526 pins arranged in four (21*21)*2 pins matrix.
I supposed that it was a sort of Power4 MCM due to this image (it has the same pin-out)

To take you off any doubt, here are some pics of a POWER4 MCM

Really nice, we should do a group buy for these

[el_gecko]

Yup

Weighing in at a very late date (while doing research on Muskies)
nowadays we call the big one a G4 MCM (c.1997)
and the smaller one is a Muskie (DK year of production)

reminder me of andamus. He disappeared for eight years. any one know what happened on him?
