David Murray (born 1975),[2] commonly known as The 8-Bit Guy, is an American retrocomputing enthusiast and video game developer who runs a YouTube channel under the same name.

[3] He worked on repairing and refurbishing iBook G3 and G4 laptops and later on MacBooks, buying and selling them on eBay, and later from his own website.

[9][10] On January 2, 2024, Murray announced that after two years of falling views and revenue, he will be forced to shift some focus away from YouTube to the X16 project and a local arcade venue he partly owns in Bedford, TX.

[23][24] Moreover, he has developed PETDraw for various Commodore computers, a pseudo-raster drawing software using PETSCII.

[16] In addition, Murray is working on the Commander X16, an 8-bit computer inspired by the Commodore 64, made using off the shelf modern parts (although with a few new old-stock chips such as the YM2151).
