A Floppy-ROM vinyl record in the May 1977 issue of Interface Age magazine. The 6 minutes of audio held Robert Uiterwyk’s 4K BASIC in the Kansas City Standard format. The program was for a 6800 microprocessor system such as the SWTPC 6800. Magazine provided by Robert Uiterwyk. Photo by Michael Holley, 22:04, 18 November 2005. The record is an Evatone sound sheet, invented by Richard Evans in 1962. They were produced until 2000. The sound sheets were often delivered in magazines. This image shows the mechanical properties of binding a record into a magazine.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
