Thank you for your interest in EMailing the Old Calculator Museum with your questions or comments. The staff is always happy to answer any questions, and address any comments, suggestions, or other issues.

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

We always appreciate folks writing us who were users or designers of vintage electronic calcualtors back in the day, with any stories of their experiences. Some of the stories from such folks are published in the museum 's Articles section. We encourage you to check them out. We also love hearing from other enthusiats who are into old calculators, and would enjoy hearing about your collection, especially older electronic calcualtors. We also greatly appreciate learning of any typographical/spelling/grammar errors, dead links, technical errors, or other errors in any of the museum's pages. If you do find such a situation, please EMail us and provide a link to the page and a description of the error. We will promptly make corrections as necessasry. Finally, if you have an old calculator that is on the museum's Wanted page, or perhaps isn't listed there, but seems as if it might be of interest to the museum for acquisition, please do let us know.

Due to the volume of EMail received, we ask that you PLEASE review the following section before EMailing the museum. It's not that we don't want to hear from you...it's just the opposite, we are overjoyed to hear from visitors to the museum, and make every effort to respond personally to all EMail we receive. However, there are a number of common questions and requests that folks have that we simply do not have the resources to continually address.

Thank you!

  • Please do not EMail the museum asking how much your old calculator is worth. We do not provide value judgments on calculating instruments. The curator will provide appraisals for a fee, but only for early electronic calculators from the early 1960's through the mid-1970s. We will not do appraisals on ancient mechanical or electro-mechanical calculators, adding machines, or on modern electronic calculators. For more information, please review the Frequently Asked Questions section.
  • The curator of the museum is not an expert on early mechanical or electro-mechanical calculators adding machines, or other ancient (comparatively speaking) devices. The museum staff has deep expertise and interest in early electronic calculators from the early 1960's into the 1970's. We 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 desktop or handheld electronic calculators.
  • The museum is not focused on nor is collecting mechanical or electric (e.g., motor-driven) adding machines, handheld electronic calculators, or ancient devices, such as abacus, stylus-driven devices, and the like. The few of these devices that are exhibited in the museum are of special interest to the curator, and are exhibited only for that reason. The general rule of thumb is if the device cannot fully automatically multiply and divide, the museum doesn't have the resources to make it a part of the museum.
  • The calculators and related items in the museum are not for sale, except as listed in the Sale/Trade section of the Wanted section. Please do not write asking if you can purchase any of the items you may see in the museum, or ask us where you might find a calculator you are looking for. If you are looking for an old calculator for sale, check the 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). Of course, if you have a question about an old calcualtor that you are interested in, or perhaps have an old calcualtor and have questions about its history, age, operation, or how to operate it safely if it is a very old electronic calculator, please do not hesitate to write to us. We will be more than happy to provide any information we can to help you out.
  • The museum is not a calculator repair or parts facility. We do not stock parts for calculators, old or new. We, in general, do not provide repair services for calculators of any sort. Likewise, we can't provide recommendations for repair facilities. We have extremely limited resources to repair electronic calculators made between 1961 and 1973. For more details on these concerns, 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. We endeavor to scan and place manuals and other documentation on the website as time and resource permits. You may find these documents in the museum's Articles section. In some cases, materials may not be able to be placed online due to copyright law. If you are seeking a manual for your calculator, and can't find it on the Old Calculator Museum site as mentioned above, please check out Katie Wasserman's wonderful Calculator Manual website first. If you don't find it there, and it is a vintage desktop calculator from between 1961 and 1976, then drop us a line. we will do what we can to provide a scan of the manual if we have it. We cannot guarantee being able to provide a scan, as some documentation is in a form that limits our ability to scan it without damaging the document, and in such cases we won't be able to help. We also can't guarantee any timeframe for how soon we'd be able to provide a scan, so you must be patient. 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. The physical documentation that the museum has in its collection is not for sale/rent/loan under any circumstance. In-person review of materials in the museum's collection can be arranged by contacting the curator via EMail.
