I'd like to share with you how I modded my Commodore 64 from 1983 to run on DC power. The mod is extremely cheap, with the total price for components well below 5$ on top of the cost of a suitable, off-the-shelf DC power adapter. Basic soldering skills are required to perform this mod. Support the Project on Patreon: https://www.patreon.com/user?u=56214619
