"My business card emulates a long-obsolete MIPS-based DEC computer, which then runs Linux" is a more accurate, and certainly significantly more impressive, description :)
Just you wait, i am working on booting ULTRIX on it, and then hopefully emulating JAZZ system and booting windows NT (video provided over virtual vnc over virtual ethernet over usb)
Windows NT had a fairly complete POSIX subsystem (for the time) [0] (but not virtualization layer) so you’d only be able to use Linux if it could compile as a rump kernel (it can’t).
That was followed by a replacement subsystem, Windows Services for Unix [1], which later used a “real” Unix compatible layer after their purchase of Interix.
WSLv1 was therefore the fourth subsystem available (though it couldn’t do some of what the previous ones did, and did some of what they couldn’t), and the complete rewrite as WSLv2 is at least the fifth such attempt.
I wish I still had my old DECStation 3100. I know there's an oil refinery near me that runs VAXStation 3100s to control SCADA systems still, in mint condition in glass-fronted racks in the control outstation buildings, with the protective plastic film still on the badges. I *want* those when they get decommed!
