It's happening again: I'm doing a pop-up exhibit showing off this (too extensive) calculator collection! August 18-20, Portland OR, visit calculators1968.com for details. Perfect for the design- or tech-minded. Hope to see you there!
A very nice overview of how 70s-era calculators worked — mixing the clarity of modern handheld calculator operations for × and ÷, but retaining "adding machine" processes for + and - for legacy users. 1/x youtu.be/V3sxIS1_R7g?si=HWLc…
Wonderful write-up by Jamel Tayeb about his visit last week to our pop-up exhibit. Great photos! jameltayeb.com/2023/08/25/ca…

Our local paper The Oregonian did a video sneak preview of the exhibit - check it out here: youtube.com/watch?v=2On8mhPt…

This 1980-ish calculator blew my mind. Two lines! It’s a good idea that apparently wasn’t worth the cost.

This Burroughs calculator has a crazy segment arrangement. This was not uncommon in the very early 70s cc @mathowie : teapawt.org/gregmaletic/status/118…

New calculator: the Minitron 871S. Croatian. The graphic treatment around the buttons, I’ve never seen anything quite like that. Still needs to be cleaned, but it looks amazing.

Cool Underwood calculator ad from 1961. (Underwood was purchased by Olivetti in 1959)

Today’s calculator: the Texas Instruments SR-22 (1973, $350). Designed for programmers, it does math in decimal, hex, or octal!

Today’s calculator: the Sears C1 (1972). One the very first LCD displays, lit by an incandescent bulb.

Today’s calculator: SCM Marchant Cogito 414, 1969.
(It worked when I opened the box 10 minutes ago. Now it doesn’t.) :(

Today’s calculator: the Texas Instruments 5100. (1976, $69.95). I love this color scheme.

Today’s calculator acquisition: the TI-1700 Dataclip (1977). Texas Instruments’ first LCD calculator. $34.95 then ($140 now). Remarkably small and thin.

Today’s calculator: the Burroughs C3103 (1971). Note the wild style of the numerals. This was common in the early 70s. My only presumption is it was appealing because it mimicked the loose style of handwriting?

What was in the box? This cool Sharp EL-8048 combo calculator/abacus from 1979. (Maybe to introduce Japanese abacus fans to the new world of electronic computation?)

Today’s calculator: the Aristo M27. From 1972, it is -incredibly- small for its day.
But why this size: why 88 x 60mm? It’s exactly the size of 5 AA batteries.
