I am available to assist in the rescue of "classic" computers from closets, attics, basements and other storage locations before they end up in a scrap yard or a landfill. I can provide a good home for these old machines, where they will be cleaned, repaired and restored to operating condition before being placed in a virtual (for web visitors) computer museum.

Before you throw out that old computer, old calculator, or old manuals, please send me an e-mail!
