David Murray , better known online as The 8-Bit Guy, is an American YouTuber and game developer for retro home computers. He is known for his videos discussing and repairing vintage electronics from the 1980s-2000s. He joined YouTube on July 25, 2006.

Murray grew up in Texas. As a child, he got his first computer, a Commodore VIC-20. He graduated from Mansfield High School in 1993.

Murray was employed at AST Research and worked in technical support. He later became employed to Samsung in 1997 due to AST Research being bought by Samsung.

David made his YouTube channel on July 25, 2006. At this time, the channel was named adric22. He really liked obtaining broken iBook laptops, repairing them, then selling them on websites like eBay and Craigslist. He uploaded his first video on March 24, 2007, which was an S-Video mod for the Commodore Amiga. After this, he made a video explaining his refurbished iBooks and how he was better than the competitors.

Sometime in 2012, David changed the name of his channel from adric22 to TheiBookGuy. He did this because he was making more videos about Apple iBooks, and wanted a more fitting username, and YouTube did not support changing of usernames until this point.

In August 2015, he once again changed his username, this time to The 8-Bit Guy, which is what it still is now. He did this because he hadn't made a video relating to iBooks for a few years at that point.

In January 2017, David announced that he would be quitting his office job and be working on YouTube full time. In February 2017, his final day at the office job came, and after that, he was officially a full time YouTuber.

Currently, he makes various videos relating to vintage electronics. He'll demonstrate these products, modernize them, restore them to new condition, and various other things. He has no set video making schedule, making videos whenever he can.
