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
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
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
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
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
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
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.
