Herb Johnson has compiled a complete web page on Laptop Information Cassette Codecs.
Audio tape cassettes of the 1960’s (developed by Phillips) had been used with the primary microcomputers of the mid-1970’s to retailer and reload applications. A number of digital requirements and circuits and applications had been developed within the interval. Private transportable cassette recorders had been cheap, dependable, obtainable; the circuits wanted on the microcomputers had been easy.
Into the 1980’s private computer systems in mass-production continued to make use of cassettes, due to their price benefit and easy digital {hardware} over floppy diskettes and drives.
Many years later, classic pc homeowners and museums of computing know-how are recovering the binary (and audio) content material from these decade-old tapes. Many of those applications are video games, and there may be explicit curiosity at the moment by players in classic computing.

Ed. observe: Even the unique IBM PC had a cassette port, though few individuals used it because it was for ROM BASIC solely and never PC-DOS. Extra on Wikipedia.
As 2022 begins, let’s take a while to share our targets for CircuitPython in 2022. Similar to previous years (full abstract 2019, 2020, and 2021), we’d like everybody within the CircuitPython neighborhood to contribute by posting their ideas to some public place on the Web. Listed below are a couple of methods to put up: a video on YouTub, a put up on the CircuitPython discussion board, a weblog put up in your web site, a collection of Tweets, a Gist on GitHub. We wish to hear from you. While you put up, please add #CircuitPython2022 and electronic mail circuitpython2022@adafruit.com to tell us about your put up so we are able to weblog it up right here.
Cease breadboarding and soldering – begin making instantly! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and extra. Construct tasks with Circuit Playground in a couple of minutes with the drag-and-drop MakeCode programming web site, be taught pc science utilizing the CS Discoveries class on code.org, bounce into CircuitPython to be taught Python and {hardware} collectively, TinyGO, and even use the Arduino IDE. Circuit Playground Specific is the most recent and greatest Circuit Playground board, with help for CircuitPython, MakeCode, and Arduino. It has a robust processor, 10 NeoPixels, mini speaker, InfraRed obtain and transmit, two buttons, a swap, 14 alligator clip pads, and many sensors: capacitive contact, IR proximity, temperature, gentle, movement and sound. An entire extensive world of electronics and coding is ready for you, and it suits within the palm of your hand.
