FYI all x86 CPUs support the 16 bit mode. Nowadays the common way to implement it is through hardware emulation (read: it looks like normal operation but it's slower than 32 or 64 bit modes would be) by using microcode instructions. They basically have a CPU inside the CPU that executes bigger instructions as a series of smaller instructions. As such, they take several cycles to complete, but since modern CPUs are several hundred times faster than a 33 MHz machine, it shouldn't be an issue.

Isn't DOS 16 bit x86 though ?

Yes but i think a person need only buy a 16 bit processer for it to work, or just ajust the code to be 32 bit.

Judging from the terms you may not distribute ms dos nor derivative works, so if you make a gui for it it will be only for you to use.

Also right,

Well, you could make it into a patch, then you are free to distribute it.
This can even be done in an installer that automatically downloads DOS and applies the patch.

Incorrect, you can not do that. Its not TI-care.org, its MS-care.org...

Microsoft STILL distributes ms dos 6...

They still distribute dos, but not windows xp

Yep, MS-DOS 6 is still in the MSDN store.

Indeed. It's Microsoft after all. But I don't know if they really care.

That is nice at least. But the rules are very restrictive for such an old piece of software few people care about.

Why did you add the sunglasses ?
Also, that's true. But the way they put it sounds like "we released the source, you can take a look at it but if you change the smallest byte, it's ours". So there's no use for that.
