As if the ulcers gained from Atmel's DMA implementation weren't enough, you just have to delve deeper ;)

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

can you then run WSL so we can get back to Linux again?

no WSL available for windows NT on MIPS

There was a subsystem for POSIX, though, it's very rudimentary from what I've heard.

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.

Maybe colinux could be hacked for that.

It's a pity they never ported VMS to it...

Presumably you could port SIMH to it.

What, no Xerox Alto?

Love your work.
