Fixing two broken VIC-20s!

Sponsored by PCBWay – check out their services at https://www.pcbway.com/ I got two VIC-20s from a subscriber that had been sitting in their basement for a long time. And let me tell you, the humidity definitely took its toll! One of them showed clear signs of corrosion, though I doubt humidity was the only culprit...Luckily, the second one was an easy repair😊 #pcbway #adv #vic-20 📌 Socials: Facebook: https://www.facebook.com/sayakasdigitalattic/ Patreon: https://www.patreon.com/SayakasDigitalAttic If you'd like to support my channel : Patreon: https://www.patreon.com/SayakasDigitalAttic ⚠️My videos are based on my personal experience and should not be interpreted as tutorials.
