[Jack Eisenmann] built an 8-bit computer out of microchips, a plastic Tupperware case, and tons of wires.
Eisenmann’s computer, which he is calling the DUO Adept, runs a small operating system he coded himself. … He made it so he can play the classic game Pong, as well as a side-scrolling adventure game he wrote called Get Muffins. The entire rig has 256 bytes of RAM (about .000005% the size of a modern computer with 4GB of ram), and a 64Kb storage system.
But while the specs may be small, there’s no doubt that the project was a monumental task for the teenager. It does seem that his smarts are paying off though, since according to a YouTube comment left by the whiz kid, he’ll be starting a job at Microsoft next month.
