Calculator Construction on Classic Macs #VintageComputing #Apple

Did you know there are several ways in which calculators have been implemented on Macs over the years? Here are some facts that you may not have heard:

Designing the calculator for the original Mac – documented through an excellent story about Chris Espinosa’s work at Apple documenting various software. After iterating various calculators and always having Jobs state he wanted changes, Espinosa developed software which allowed changes to the calculator in real time, dubbed the “the Steve Jobs Roll Your Own Calculator Construction Set”. After about 10 minutes of fiddling, Jobs found an acceptable calculator design and that was shipped on the original Mac. More at Folklore

Calculator Construction Set – this was an app by Dubl-Click Software in 1989, which ran on System 6.x as noted by Joe Groff on Twitter last month.

Modern versions?? – There is interest in reviving some of the beautiful, clean lines of all the classic Apple calculators. Richard Sterling on Twitter posted that he would consider creating physical calculators. My how clean design is favored through the years.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
