The Pentium II did have 512 KiB L2 cache, not 256. Never the less, you are absolutely right that in a lot of applications, the Celeron "450A" was faster than the PII

You're right. All the Klamath, Deschutes Pentium II and Katmai Pentium III have 512 kB half speed L2 cache. They need Slot 1 and there are no Socket 370 versions avaiable.
I've messed it up with the Coppermine Pentium III's which had 256 kB L2 cache, on die and full speed. They do not need Slot 1 and they exist in both Socket 370 and Slot 1 variants.
I fixed it.

There's nothing wrong with Celerons. Newer Celerons are often faster than older Pentiums, for example. There are also plenty of good OEM cards from this era.

The right choice of components really comes down to what software you want to run and what your hardware will support. Not all early Intel chipsets can run Coppermine anyways, so there's no point in buying as processor purely based on what you want.

I just was digging in a box and found a Celeron SL2Y2. It is a Covington 300 with the newer A1 stepping.
Is this any good for? Can it be paired with a S3 Virge on a Legend QDI P6I440EX/ATX EXCELLENT 1?

Well, it's not worth hunting for a Covington. You just can emulate its behavior with a Klamath/Deschutes Pentium II, a Mendocino Celeron or a Katmai Pentium III. Run it at 66 MHz FSB and disable L2 cache.

Another spring, another municipal waste collection day. Wife was NOT happy but she helped me anyway. That's true love.

Wow, did you find the PS/2 there?

As in driving around the streets and picking up stuff from the curb? But yeah, she's a keeper

From the side, those look like Dell Dimension 8100s! Am I right?

Here's some free stuff that was destined for the dumpster.

1. Maxware 8086 (NEC V20)
2. WDC Paradise '88 VGA 16-bit (8-bit friendly)

Does anyone know if I can use my AT power supply with this board? There's 12 pins and plug looks similar but more primative.

Someone here will.

If it's indeed an AT connector, it called a Molex 90331:

If the middle 4 pins all lead to ground, I'd say, pretty good chances.

But that thing looks really fossil, even to an old geezer like me.

I'll give it a try it, one day, and wear glasses in case a tantralum blows up in my face. It's old but hopefully I can use this to verify if my PSU is still working, I also have a 486 that won't fully POST and I'm not sure if it's the 486 or PSU.

The NEC V20 is the replacement for the 8088, while the v30 is the replacement for the 8086.

I had the same question a while ago. I'm 99% sure you can safely plug your AT PSU to this connector (provided of course you stick the black wires next to one another, the same way you would with an AT board)

Saved this HP NetServer E50 from being scrapped today, feels good.

Nice job saving that beautiful machine.

Thanks! It's absolutely full of dust though, it was actually still running(!!!) when it was decommissioned today.

Wow that's had quite the long deployment life. Once you get it all cleaned up and looking good it'll be a fun system to tinker and play with.

I think this is is one of those classic "nobody remembered it was there and so nobody turned it off" stories, which are always a good story.

I've seen that happen a few times in the past. Always makes for a good story.

Thanks for the confirmation. I'm pretty sure it will too, I'll post an image of it running if it does end up working.
