    The "4" in "4/500" tells it's an EV4 (at 500 MHz).

    They manufactured EV4 with 500MHz? And put them in AS800s?
    I kind of doubt that. IIRC, the AS800 was an EV5 machine, with all the
    EV5 above and including 400MHz being EV56.
    What's an EV3 supposed to be? PRISM?

    Plenty of AlphaServer 800 info is still available at
    http://www.compaq.com/alphaserver/archive/800/ (assuming that you mean
    AlphaServer 800; there don't seem to be other obvious candidates).

    Is there a particular reason you want to know whether it's EV5.6 (aka
    21164A) rather than the other (remote) possibility (EV5/21164)? I'm
    reasonably confident this family were EV56, but not 100%. If your
    interest is byte/word addressability, please check section 14.9 of the
    VMS FAQ at http://hoffmanlabs.org/vmsfaq/vmsfaq.txt which may shed
    more light on the subject, depending on your needs.

    I'm not aware of any EV3 boxes that saw light of day as commercial
    products.

    You're remembering right. Sorry for causing confusion.

    Alasir has a nice overview of the history of Alpha chips at
    http://www.alasir.com/articles/alpha_history/index.html

    So then, the nomenclature that I thought I understood was not so
    clear after all. With that, it should have been named 5/500.

    I'm thinking that there was no such thing as a AS 800 4/500.
