I suspect the boards are almost as unicorny as the CPU

With having too much stuff, it sounds like I wouldn't know if I had one, I've only found the easiest to find stuff 🤣 .... I'm 99.9% certain I don't though.

Edit: gotta leave that 0.1 hanging because a couple of years ago I would have been fairly certain I didn't have an IBM BL3 but one turned up.

I'd like to have your house address. I can get there with a team and go through the warehouse.
We have oxygen tanks, lower levels aren't an issue.

Working perfectly !!!
The HWINFO program identified as Cyrix.
I found a bit more information about this processor:

Actually Bitwranglers basement is likely more dangerous than Mordor so carry on.

so this doesnt use standard 386 pinout? pictures above show normal PCChips M326

Yah I suspected wrong, I was thinking it was gonna need 3.3V and need some other support like some TI DLC or other OEM only one.

Couldn’t prove it by me, I thought all of the oldest off brand DLC laptops had those strange MC labeled CPUs inside.

I never knew Eagle had a fab (or an x86 license), so I wonder where these chips really came from.

Does this software normally identify DLC type CPUs as a 486S?

The reason I ask, is I wonder if any leftover 486S dies (with 2kb cache) might have been repackaged for use in 386 systems.

found a Pentium 4 2.8Ghz 400Mhz Northwood (SL7EY)

first time i see a p4 400Mhz clocked so high, according to Cpu world this one is rare and the 3Ghz version is basically paper launch

it came out of an IBM Baby Desktop with i865g and no AGP

Dunno if it's super rare, but unusual NS486SXL-25 QFP CPUs turning up for cheap on fleabay.

Weren't these common, not rare? I thought the P4 2.8GHz 400MHz FSB's came inside early 2000's small business oriented pre-builts like the Sony Viao PCV-RS series and similar models from HP.
FWIW I've only ever seen the P4 2.8GHz 400MHz FSB in motherboards without FSB jumpers.

Im pretty certain the SL6YH - P4 3GHz with 400MHz FSB is not as rare as people think as well. You can find them for 50 bucks or less, I found several for sale right now.
IIRC, they were an upgrade option for said early 2000's small business oriented pre-builts.

I think 2.8 prescott chips were very common and the 533 bus northwood chips were not rare, but the 2.8 northwood chips on a 400 mhz bus were a short lived OEM release.

They're also not pin compatible with 386SX as far as I know, so not terribly useful.

Aren’t those basically for 386dx systems?
132 pin is a bit strange

The NS486SXL is not related to the TI486SXL (which is 386DX pin compatible).
It has a 16-bit external bus. The reason for the 132-pin package is because it seems to integrate the motherboard chipset. It's advertised as a "system on a chip".
It's also "protected mode only". No real mode or virtual 8086 support. Not DOS compatible.

Just scored a new in box quick chip 233 gold top winchip. Those seem to be a little hard to find, though not terribly exciting as they are kinda slow. More of a collector item than anything.
