    Item is vintage and as such has marks and wear from age and use.  It was working when decommissioned decades ago.  It powers up, but there’s no guarantee that it still works.
    Please look at the pictures carefully and ask any questions before purchasing.
    One of the pictures shows that a few of the S-100 bus connectors do not have the right mounting tab.  I don't know what that's about.
    This computer will be carefully packed and insured.  This machine was custom built and modified by the builder.  This computer is sold AS-IS.
    Here are some more pictures.  Please message me if you have questions.
    This was my first computer and I have some other parts for it please let me know if that's something you'd like to see listed.
