Antique adding machines

This amazing website has a lot of photos of Aaron Adding Machines portable calculators made around 1953. All calculators are small enough (for mid 50’s of cause) and equipped with cold-cathode tubes for displaying results of calculations. It’s pretty advanced for those days.

But what’s really interesting for modern people, is their look and feel. Natural wood, bronze – what’s no one of modern cheap as a dirt credit card sized calculators can’t offer.

  1. Quote from above “All calculators are small enough (for mid 50’s of cause) and equipped with cold-cathode tubes for displaying results of calculations. It’s pretty advanced for those days.”

    This is not the case.

    Andy Aaron makes these now, not in 1953. One of the wooden boxes he used has 1953 stamped on it.
    These are pieces of art, made in a pseudo-retro style similar to steampunk.

    The electronic calculator was first released by IBM in 1954, and it didn’t fit in a box.

  2. Thanks for mentioning my website. In fact, these calculators were all built between 1983 and 2007. They’re based in 1970s calculator technology – they have red LED displays and pretty basic functions. But I make all the exterior hardware out of real antiques and found objects, including old switches and buttons. There are lots of hand-soldered wires inside, connecting all the old stuff to the digital chip and display module.
