Blast fromm the past.. what speed though?

does it matter? lol

my computer is so fast, it completes an endless loop in less than 4 seconds!

I don't have any references but I'm almost possibly sure it's a 486-class processor often sold from evergreen technologies as an overdrive processor. It runs at 133 and thusly has a Pentium P75 rating. You can easily get that sucker to run at 150 if you want P83 speed.

Dichromatic for your viewing plesure...

You have a genuine rare 586 processor and this was one of the fastest ever made! It was basically a very fast 486 and the last of its kind brought out by AMD before they upgraded to the K5 line which used a totally different socket. This chip will fit into a socket 3 which is the same one used by all 486 processors so if you have an old 486 motherboard try it! It probably won't work however unless the board is a fairly late model capable of running at least a 486DX4 100 overdrive. The chip runs at 133 MHz but is only equivalent to an old Pentium 75 in performance (which was around at the same time) hence the reason for the P75 rating. It was much cheaper to purchase however and gave late model 486 owners a cheap alternative to upgrading to the performance of a base model Pentium without having to change their motherboard. I had one in my early days of computing and loved it! It was able to run quite demanding games which you wouldn't have considered on a 486 and was very efficient as an office PC.

Wow, reading some of this is like reading about household life before indoor plumbing was a social norm...lol

Thanks for the links..

Its a shame, a buddy of mine just trew out a board with an amd 8088 cpu on it. He tried to save it for me (Im trying to collect cpu's)but it shettered when he tried to break it off the board.

Oh well, just have to search those comps put to the curb!

If the Scatman can do it so can you...

I have two of these, and they are sort of rare. I'll be selling them soon on eBay. Like the other guys said, they're a 586-133. Basically it's a 486 with some feature added I think. And it's PR75 rated. Now, this is impressive give that the P75 used a 50MHz FSB and the 5x86 used a 33MHz FSB! But you can actually get PR100 performance if you have a board that supports the 50MHz bus speed and set it at 3x50.

They didn't just fit Socket 3, they also fit Socket2. Socket2 had extra pegs for the heatsink, in the same locations as Socket7, 370, and 462! So if you find a rare Socket2 board that supports 4x multiplier and 50MHz, using 5v (instead of 3.3v) core you can probably get the thing to run 4x50=200MHz, using an Athlon cooler!

Thanks for the link. But I never found anywhere else about AMD cpu's older than 80386 clone
