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
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.
- 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
- 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
- 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.
