nice old topic .... i would say if this isn't a microchannel slot, its the cpu-card slot

I just got a board that looks just like Tonyo's, my IBM FRU is 51G8631.
After checking out the IBM Power page on Wiki found here
http://en.wikipedia.org/wiki/IBM_POWER
I am wondering if the silver IBM chip is a Power1 cpu.
POWER and RS/6000
In February 1990, the first computers from IBM to incorporate the POWER Architecture ("Performance Optimized With Enhanced RISC") were called the "RISC System/6000" or RS/6000. These RS/6000 computers were divided into two classes, workstations and servers, and hence introduced as the POWERstation and POWERserver. The RS/6000 CPU had 2 configurations, called the "RIOS-1" and "RIOS.9" (or more commonly the "POWER1" CPU). A RIOS-1 configuration had a total of 11 discrete chips - an instruction cache chip, fixed-point chip, floating-point chip, 4 data cache chips, storage control chip, 2 input/output chips, and a clock chip. The lower cost RIOS.9 configuration had 8 discrete chips - an instruction cache chip, fixed-point chip, floating-point chip, 2 data cache chips, storage control chip, 1 input/output chips, and a clock chip.
A single-chip implementation of RIOS, RSC (for "RISC Single Chip"), was developed for lower-end RS/6000's; the first machines using RSC were released in 1992.

Where did you get that layout map? I'm desperately searching for a RS/6000 7013-570 CPU planar layout to identify the POWER 1 chipset on it.
i dont find yours (I find 7013-591)
sorry

And if we stay on that way, the processor is probably a Power 601 at 45Mhz :

it's a very very close mother board with some little difference
And in that motherboard, it's a Power 601 33MHz processor ( U8 )

YA The "SCSI" Slots are not the 8 simm slots.I was able to get a closer look at the board.They are away from the simm slots...(I know what simm slots are thanx
)
Yup your right, the dx-25 is a chip of sort, not a proccessor...oh well...
There's nothing "standard" about this board ! It is a server board of sort, I've seen it in one before ! The only thing I can't tell for sure(as well) is what the CPU is other then the 386/486 talk .

the FRU number of the motherboard is 51G8375.
On google I found that's a 7011-230 SYSTEM BOARD.
And when I search about that (7011-230 SYSTEM BOARD), i found : IBM RISC System/6000 Model 7011-230
And on the motherboard there is another FRU number ( on a sticker), and google said : IBM RS6000 51G8379 : IBM System Planar

the chip that ended by DX-25 is : KU82596DX-25
as I said the only chip that can be the processor is this grey IBM !!!!
I join a pic of the bootom of the card ... look the socket of the IBM ... it dont look like to a 486 ...

The board looked to me like a standard PS2 motherboard, nothing complicated about it. FDC, IDE, 8 simm slots, standard stuff really
The chip that ended in DX-25 isn't a CPU - it's part of the chipset (although I can't say exactly what as the page is currently unreachable, or I ahve set something up wrong in Firefox when I reinstalled tonight).
The "Lots of SCIS connectors" (excuse me copying the spelling msitake as well, it amused me) must be the 8 simm slots - only thing I can see lots of
I guess that the angle they are at confused you - I've seen them like that one a number of boards, and I know my PS2 has simm sockets that are the same.

...humm.... Think I see a Intel DX-25 chip on there....A Co-proccessor or...Maybe THE proccessor?
This also looks like a server board for something I've seen before...just can't remember...
Lots of SCIS connectors too.

Looking at
http://www.cpu-world.com/info/IBM-parts.html
I note that all IBM parts recorded which start with 50G are 486, and most are either 486DLC or SLC chips. 50G6663 is a 80486SLC2-66, so I would GUESS (I don't know) that it is a 486SLC2 (the only real way to test if nobody knows the specific part number is if the board is working, run a decent CPUID prog which can identify all the Cyrix/IBM CPUs).

ok so where is the cpu on the motherboard ??
This chip is the only with an heatsink !

It`s not a CPU, I think it`s a DMA controller.
