Thanks for your interest in EMailing me with your questions or comments. I'm always happy to answer any and all questions, and address any comments, suggestions, or other issues you may have. Due to the volume of EMail I receive, I ask that you please read the following section before EMailing me. It's not that I don't want to hear from you...it's just the opposite, I'm overjoyed to hear from visitors from the museum, and make every effort to respond personally to all EMail sent to me. However, there are a number of common questions and requests that folks have that I simply do not have the resources to continually address.

Please read the FAQ for answers to commonly asked questions about the museum before sending me EMail. It will save both of us time if the questions you have are already answered there.

Thank you!

  • Please do not EMail me asking how much your old calculator is worth. I do not provide value judgments on calculating instruments. I will do appraisals for a fee, but only on early electronic calculators from the early 1960's through the mid-1970s. I do not do appraisals on electro-mechanical or mechanical calculators, or on modern electronic calculators. For more information, please read the FAQ.
  • I am not an expert on early mechanical or electro-mechanical calculators or adding machines, or other ancient (comparatively speaking) devices. I have deep expertise and interest in early electronic calculators from the early 1960's into the 1970's. I would suggest checking out some of the websites in the LINKS section of the museum to find resources for more information on earlier mechanical and electro- mechanical adding machines/calculators, and on later handheld electronic calculators.
  • The museum is not collecting mechanical or electro-mechanical adding machines, handheld electronic calculators, or other ancient (comparatively speaking) devices, such as abacus, stylus-driven devices, and the like. The general rule of thumb is if the device cannot automatically multiply and divide, the museum doesn't have the resources to add such equipment to the museum.
  • None of the calculators or other items in the museum are for sale (except as listed in the Sale/Trade section of the WANTED page). Please do not write me asking if you can purchase any of the items you may see in the museum, or are looking for. If you are looking for any old calculator for sale, check the World Wide Web auction websites (such as eBay), online classifieds (e.g., Craig's List), and visit thrift stores, estate/garage/yard sales, and lastly, visit other calculator-related websites (see the LINKS page).
  • The museum is not a calculator repair or parts facility. I do not stock parts for calculators, old or new. I also, in general, do not provide repair services for calculators of any sort. Likewise, I can't provide recommendations on repair facilities for any calculator made after 1973, and have extremely limited resources to repair electronic calculators made between 1961 and 1973. For more details on these issues, please read the FAQ page.
  • The museum does not stock nor sell manuals or other documentation for old calculators. The museum maintains a collection of vintage calculator documentation, but it is for preservation and reference for the museum. Please do not write the museum asking if we have a manual for your calculator, unless it is a vintage machine, and is listed as existing in the museum's calculator collection. The museum has no documentation for any calculators later than approximately 1976, so if you are seeking documentation for a machine that was made after 1976, we won't have it. Some documentation is scanned and placed online in the form of PDF documents, which will be listed in the ARTICLES section of the museum. In some cases, materials may not be able to be placed online due to copyright law. If you are seeking a manual or documentation for an old calculator, check the Articles section first. If it isn't there, then it's likely either not available in the museum's collection, or it is in a form that makes it difficult/impossible to scan, or placing it online would be in violation of copyright law. None of the physical documentation that the museum has in its collection is for sale or rent/loan under any circumstance. In-person review of materials in the museum's collection can be arranged by contacting the curator via EMail.
