minus-squareduncan_bayne@lemmy.worldlinkfedilinkEnglisharrow-up1·edit-24 months agoHaha my first thought was “I wonder if it’s possible to build a general purpose CPU out of 555 timers, then get DOOM running on that sucker.” Of course, someone has already taken the first steps towards such a monstrosity. https://hackaday.com/2021/12/17/implementing-a-cpu-using-555-timers-and-logic-synthesis/
