[Humanoido] put the setup together for a total of 1280 ports, 640 counters, and more all running at 6.4 billion instructions per second for the low low price of 300-500$ by our count. The “skyscraper” even comes … Read the rest

This reminds us of the Chipophone, only this time the sound is achieved from ICs used back in the day, rather than MCU … Read the rest
