The Brother GeoBook NB-60 is an old laptop from the 90s that was primarily used for word processing, accounting, and not much else. The laptop had a 1.44MB floppy drive and also a hard drive.
Action Retro got their hands on one recently, and with the internet being the internet, someone who worked at Brother ported Wolfenstein 3D many years ago. They sent a copy over. A YouTube short shows the game in action. Although the screen refresh rate can’t keep up, it runs quite well given that it’s on a laptop designed for word processing.
