Repairing The Legendary Gravis Ultrasound

I never owned a Gravis Ultrasound back in the day, but always wanted to get one to explore the very different and interesting sound experience they provide. Unfortunately, they've become ridiculously expensive over the years, so I could never bring myself to buy one. So rather than shelling out a huge amount of money, I bought a broken one instead! Will I be able to repair it? Or was buying this defective card a big mistake? ** My Blog: https://vswitchzero.com/ Follow me on X/Twitter: https://x.com/vswitchzero Mastodon: https://bitbang.social/@vswitchzero If you enjoy my channel, please consider supporting me on Patreon: https://www.patreon.com/vswitchzero ** 00:00 Introduction 01:15 A Brief Look at the GUS 05:45 The Test Setup 07:15 Software Woes 08:50 Testing the Broken Card 12:25 The Plan 14:11 Spring Cleaning 15:51 Problem Identified 17:43 A Sketchy Workaround 18:39 The Proper Fix 20:17 Replacing the Crystal 21:52 The Result 22:43 Fixing it Again 24:15 Upgrading the DRAM 24:4
