A (Virtual Machine Disk) is the native disk format for VMware virtual machines. Creating a functional VMDK with Windows NT 3.1 allows retro-computing enthusiasts, security researchers, and historians to boot and explore this milestone OS without vintage hardware.
Finding a working Windows NT 3.1 Advanced Server VMDK is difficult because it required a dongle (hardware key) for the OEM version. Most preserved VMDKs have had this dongle check patched out.
Windows NT 3.1 was the first operating system to implement the Win32 API comprehensively. This was the application programming interface that allowed 32-bit applications to run, paving the way for the software ecosystem we have today. Using a VMDK of this system allows developers to test the earliest 32-bit binaries in their native habitat. windows nt 3.1 vmdk
If you want absolute legitimacy, do not download a pre-made VMDK. Build it:

: Unlike modern Windows, you can't just boot from a CD. You usually have to "feed" the virtual machine a series of 20+ floppy disk images ( .flp or .img ) just to get the installer running. How to Make it Work
