I brought a Wang 360 calculator console back to life with a modern “Electronic Package”. Not only does it emulate the original Wang calculator’s behavior, but it can operate as a nixie clock or as a Reverse Polish Notation calculator.
The Wang 300 series calculators consisted of an Electronic Package (as Wang called it), where calculations were executed using discrete diode-transistor logic, and up to four keyboard/display consoles. The consoles were basically dumb terminals: they were connected to the Electronic Package (EP) via a 30-conductor cable. The EP scanned the keyboard for key presses and displayed digits on the multiplexed nixie tubes.
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.
