- RAM: 12 MB minimum (16 MB recommended). NT 3.1 cannot handle more than 2GB; modern motherboards will crash.
- Storage: 90 MB for Workstation, 110 MB for Server (SCSI or IDE drive under 8GB)

- Network: Novell NE2000 compatible (Good luck finding one).
- Optical Drive: A vintage CD-ROM drive on a SCSI or IDE controller.
Realistic advice: Do not try to install on real hardware unless you own a 486 tower from 1994. You will want an emulator.
Overview
Windows NT 3.1 was the first version of Microsoft's high-end operating system line. Unlike Windows 3.1 (which ran on top of MS-DOS), NT was a complete 32-bit operating system written from the ground up. It was designed for business and professional use, offering stability, security, and hardware abstraction that consumer Windows versions would not achieve until the release of Windows XP in 2001.
