  1. Fellows, i'm doing some bech tests with this FPU/Math Coprocessor from IIT company.

    It's basically a cpu dedicated to process floating point unit operations.

    Since 486dx they were embedded in this cpus, but in 386 era they were provided separately by some companies, IIT is one of them.

    Any more information you guys need i'll be more than happy to provide :)

    Reserved it for me.

    Sorry for asking, but wasn't you who mentioned in another thread that you already have like five or six rex?

    Are you binning it or something?

  3. Thanks A LOT :)

    It is correct, amd "clone" version of original intel 80386sx, Cyrix made their ones too.

    Back in middle 80'ies Intel had a deal with Amd and other companies that allowed then to produce their own 386, but they are essencially all the same cpus" ng80386sx ;)

     

    Edit: This is the datasheet from amd 386 processors, along with a table from wiki (the info is correct, i checked it in the datasheet):

    http://pdf.datasheetcatalog.com/datasheet/AdvancedMicroDevices/mXwtys.pdf

    Model number Frequency FSB Voltage Power Socket Release date
                 
    AMD Am386SX/SXL-33 33 MHz 33 MHz 5 V 1.35 Watt 100-pin PQFP 1992

  4. I did a print screen with some information that might help.

    Unfortunately this old cpu is not compatible with cpuz or any other "modern" cpu id software, but i used old norton system info and checkcpu windows 3.1 software to help identify it.

    I also want to know if a print screen like this will be enough for a future superpi1m validation run? I did a "quick" superpi16k run as an example.

    @Leeghoofd or @Antinomy i would apreciatte some help with this.

    If you guys need any other info please quote me here.

    Thanks a lot.
