I don't have any socket 8 stuff anymore but if I did I'd have been all over that. These interposers taking systems where they were never supposed to go are *chef's kiss* - so much fun!

Speaking here as someone who so far has collected 3 socket 5 Powerleaps and an Evergreen along with a socket 4 Pentium Overdrive. And a bunch of POD/Evergreen/PNY/Trinity Works stuff for 486 sockets. And just about anything that can fit in a 386 socket.

More on this stuff here at The CPUShack.

Ardent Tool of Capitalism has no Pentium Pro section but is otherwise a great resource for collectors.

Yeah I'd say it was well worth the ~$190. These are super rare

Thanks everyone. This is a super cool piece. I’d love to see some benchmarks. No doubt the CPU is hindered by PCI and EDO RAM, however, I’m thinking it must be several times faster than a 200Mhz Pentium Pro and still much faster than the PDOP333.

Any idea if the 766 Celeron could be swapped with a P3 or faster Celeron?

I'll hijack the thread just a little bit, but I swear I'm still almost in-topic.
It's now common knowledge that Coppermine CPUs need at least a 440EX or newer chipset to work. On LX and (supposedly) very early i810 everything goes very wrong very quickly as soon as the first instruction involving SSE is run.
How does the 440FX behave when running a Coppermine?

Not hijacking at all. Trying to learn as much about this chip as possible and you bring up some valid concerns. Thanks.

Finding one with a high enough multiplier to “perform similarly “ while being compatible with that generation socket is likely small.

So yes you can but also probably not as useful as you would think

On a good platform (say BX/815/694) the celeron 766/66 should perform about the same as a P3 600/100 more or less.
The "best" upgrade on the upgrade could be (let's ignore the socket differences for now) a Celeron 1400/100/256 that would run at 933 Mhz with the 66Mhz bus.
Maybe 1.change GHz if you can overclock the bus to 75.
But why though? The 440FX platform would be bottlenecking hard a 533A already.
