Hah I love this. It's a quaint blend of modern and old

DJGPP and Allegro really gave DOS powers it didn't have

Good times but I certainly enjoy the convenience of modern OSs

Now Win 3.11 can be run on a GIT built FreeDOS. If anyone wrote some Win 3.11 replacement for DOS by reusing some Wine code, (and Calmira Desktop on top) it would be great for legacy 386 machines.

It's not like we have _that_ many 386 machines. Like 80% of the mobos around got some traces damaged because of battery leaks. Capacitors in ancient AT power supplies explode out of blue, etc, etc.

DOS based Windows (like 95, 98, ME)

Those Windows versions were a proper OS as well, MS-DOS run inside a virtual DOS box or rebooting into it.

Does Windows 10 still come with DOS compatibility?

Dalewyn• 3 years ago

Windows NT has absolutely nothing to do with MS-DOS.[1]

This was a rather sore point back in the days of Windows NT 3.1 and NT 4.0, when a lot of software was still written for DOS and simply couldn't execute on NT.

All 32-bit versions of Windows NT up through Windows 10 have NTVDM (NT Virtual DOS Machine), which as the name suggests is a virtual machine which virtualized DOS.[2]

However, this "compatibility" afforded by NTVDM still failed in most practical situations because most DOS programs were written with the assumption of direct hardware access being available. NTVDM's purpose was instead to facilitate running 16-bit software originally written for the likes of Windows 3.1 and early days of Windows 9x.

All 64-bit versions of Windows NT do not incorporate NTVDM due to hardware limitations and consequently cannot execute any 16-bit programs, including software for DOS.

From my reading of that piece, Win9x had its own kernel that was a descendent of DOS; it was not just an application running atop DOS like Win 3x. Consequently it lacked proper memory isolation and security features compared to NT but it did at least bring preemptive multitasking.

Still longing for the source leak or dump like Apple did with LisaOS so we can have the theory confirmed, then have a play with it ourselves.

DOjS is pronounces like doge, but ending with an "s".

Doge is pronounced Dough + Je(french). I have no idea how you then make an s sound after that without it sounding quite odd!

weikju• 3 years ago

I read that more as "Doze", like the ol' derogatory "Windoze"

codetrotter• 3 years ago

Probably the same way you’d pluralize doge.

LoveDOS was a similar project with Lua: https://github.com/rxi/lovedos. It is now archived.

Retroactive programming; where whether we could always trumps whether we should. And who will question the unholy offspring? It is equal parts glorious and terrifying.

The number of systems still running DOS is small, but shockingly stable.

I worked at a book store on my university campus in 2011 and the entire inventory management system was on a DOS system, I believe running on a VM (but possibly not...).

giancarlostoro• 3 years ago

Maybe it was on a FreeDOS VM, I cant remember the name but I could of sworn there was a software that also simulated DOS and ran as a regular windows program.

Edit: DOSbox apparently

tenebrisalietum• 3 years ago

I bet there is a lot of DOS driving menu/kiosk displays, POS systems, and machine control things that just simply never needed to be upgraded.

ElfinTrousers• 3 years ago

Technically speaking this is kind of cool...but why spend all this time and energy on writing dev tools for an OS that's decades out of date?
