So, what do y'all think about this one. Bought on an auction site with little description. Couldnt see the etched speed marking in the corner - well because it wasn't there.
It has a cut Pin A4, which is consistent with an early POPD5V, but Gemini suggests it's a 63 though.
It has one more decoupling cap than my known PODP5V83 but no laser etching on the heat sink.
Heat sink looks sligthly smoother than the known 83, but ALL over, even on the raised part, so doesn't look like it's been altered.
Here a picture next to my 83. Gimme your thoughts, please.

If it's dual it's kind of cool ... 😎

Got the chance today to shoot some photos under a microscope.

Put a little IPA on the corner, where the speed is usually laser etched to experiment with how light refracts. I even rubbed it a bit with my finger nail. Wouldn't put anything on the heat sink due to the hand written text.

Any thoughts whether this is legit? I can't see any signs of alterations in terms of machining marks or anything.

Maybe ES == "Engineering Sample" ???

Allegedly yes, but I can't find ANY other PODP5V83 or PODP5V63 for that sake online as engineering samples, so I have no idea if this is a legit Engineering Sample or some remarked part.

Waiting to find a disk or CF card of max 8 GiB for my 486 build to install NT4 so I can get some stepping data etc. from the CPU.

Try CHKCPU and NSSI for CPU stepping info.

Haven't gotten an OS up and running yet, I'm challenged on IDE storage in the sub-8GB range ... does run the NT4 installer at 83, though, but due to the 16gig CF card, system won't boot. Double checked with my known 83MHz to verify it wasn't a CPU issue
