Do you have chips that you've never seen anywhere else?

Of course it's real, uses a 3x50 combination to get 150mhz. Most of the motherboards aren't able to use a 50 Mhz fsb, because it was problematic with Vesa Local Bus (with a 50 Mhz bus yo are only able to use one VLB card,with a 33 Mhz bus you can use up to 3 VLB cards) and for that cause a little number of 50mhz bus processors were made (like the Intel 486DX-50)

should be 4x40 as the 5x86 supports both 3x and 4x multipliers.

I checked under loupe. No hand remarkings. This AMD produced ? We will never know ! I receive answer from AMD technicians. They gave me links to AMD pages and they said : only that CPUs are made (on web page).

I found this one last week:

I've never seen anything like it. Some sort of Pentium 75 sample with an attached heatsink, but it has an interposer on the bottom with extra pins compared to a regular Pentium and a wire from one pin on the CPU is connected to an adjacent pin on the interposer. I've been asking around if anyone can identify it but I haven't had any responses. I also can't figure out why it shares a sspec number (there is a Pentium Pro ES that is also Q033).

show us the bottom please, that is very nice

Very nice!

Can i add your picture to the cpu picture library, since this is just "never seen before"? Check my signature.

The wire is hardwired BF jumper. Nice one Smile

The bottom is the not so nice part. The previous owner let some of the interposer pins get broken, but the good news is that the actual CPU pins are perfectly fine. Does anyone know where I might get a new interposer so I can make this chip look perfect?

I tried to look up which pins were jumpered but those two were outside of my Socket 5/7 chart. And yes, you can add my photo to your library.

(I don't know why there are "shadows" on some chips, anyone could help me please ? Very Happy

(NB : we can see the same printing "IT'S ST / ST486 / DX2-66... etc. under the purple paint)

remarking was fairly common, not just illegal marking, often a chip top was cleaned for markings of another company, and then remarked, perhaps that ST had been cleaned to be remarked as a Cyriix etc, and then ended up back as an ST.
