As he explains in the video, which has been translated from Polish with the aid of AI: &#8220;It started with collecting a large amount of old memory chips. I started experimenting with them and quickly realized you can make some really cool things out of these seemingly useless really old things.&#8221;<\/p>\n<p>Initially, MINT was just using those outdated memory chips for simple tasks, like controlling a motor or light dimmer. But eventually he figured out that by combining several memory chips, he might be able to make a fully-functioning 8-bit CPU.<\/p>\n<p>Over the course of the half-hour long video, MINT lays out the lengthy process that went into accomplishing this. Not only did he build and solder the CPU himself, he even spent &#8220;hundreds of hours&#8221; writing the code for it. If you&#8217;re interested in the finer details of how computers work, MINT&#8217;s video is an interesting deep dive into all the components and how they interact with each other to execute commands.<\/p>\n<p>The end result is the &#8220;EPROMINT CPU.&#8221; As a proof of concept, MINT hooked it up to a small VFD display and programmed it to play scenes from The Matrix. They obviously come through pixelated, but it works nonetheless.<\/p>\n<p>As MINT put it: &#8220;It doesn&#8217;t require a team of people or a multi-million dollar budget to build, yet it&#8217;s a fully functional processor, and simple enough I can explain how it works.&#8221;<\/p>\n<div class=\"product\"><a data-dimension112=\"526c6594-7226-4fb0-844b-04f6e619dcc3\" data-action=\"Deal Block\" data-label=\"2025 games\" data-dimension48=\"2025 games\" target=\"_blank\" rel=\"nofollow\"><\/p>\n<figure class=\"van-image-figure \" >\n<div class='image-full-width-wrapper'>\n<div class='image-widthsetter' style=\"max-width:400px;\">\n<p class=\"vanilla-image-block\" style=\"padding-top:100.00%;\"><img loading=\"lazy\" decoding=\"async\" id=\"Vji3V6i3HDWUHeQ22PrjFL\" name=\"New Project (8).jpg\" caption=\"\" alt=\"\" src=\"https:\/\/arcader.org\/wp-content\/uploads\/2025\/07\/a-diy-mad-scientist-from-poland-built-his-own-cpu-out-of-dozens-of-ancient-memory-chips.jpg\" mos=\"\" align=\"middle\" fullscreen=\"\" width=\"400\" height=\"400\" attribution=\"\" endorsement=\"\" credit=\"\" class=\"\"><\/p>\n<\/div>\n<\/div>\n<\/figure>\n<p><\/a><\/p>\n<p><a href=\"https:\/\/www.pcgamer.com\/games\/new-games-2025-upcoming-pc-release-schedule\/\" data-dimension112=\"526c6594-7226-4fb0-844b-04f6e619dcc3\" data-action=\"Deal Block\" data-label=\"2025 games\" data-dimension48=\"2025 games\" data-dimension25=\"\"><strong>2025 games<\/strong><\/a>: This year&#8217;s upcoming releases<strong><br \/><\/strong><a href=\"https:\/\/www.pcgamer.com\/the-best-pc-games\/\"><strong>Best PC games<\/strong><\/a>: Our all-time favorites<br \/><a href=\"https:\/\/www.pcgamer.com\/the-50-best-free-pc-games\/\"><strong>Free PC games<\/strong><\/a>: Freebie fest<br \/><a href=\"https:\/\/www.pcgamer.com\/best-fps-games\/\"><strong>Best FPS games<\/strong><\/a>: Finest gunplay<br \/><a href=\"https:\/\/www.pcgamer.com\/best-rpgs-of-all-time\/\"><strong>Best RPGs<\/strong><\/a>: Grand adventures<br \/><a href=\"https:\/\/www.pcgamer.com\/the-best-co-op-games\/\"><strong>Best co-op games<\/strong><\/a>: Better together<\/p>\n<\/div>\n<\/article>\n<p><a href=\"https:\/\/www.pcgamer.com\/hardware\/a-diy-mad-scientist-from-poland-built-his-own-cpu-out-of-dozens-of-ancient-memory-chips\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>You might be reading this on a gaming PC you built yourself, but you probably can&#8217;t say you built the processor from scratch with your own hands and a soldering iron.
