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)
Excellent work, excellent writeup. Hopefully those lucky should who receive these cards from you understand how much sweat and blood went into them!
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.

Love your work.
