A fantasy ARM based PC and native ARM port of DOS+Apps with Rosetta-like x86 JIT

A bit of alternate history: What if IBM had gone with an ARM instead of x86 for the IBM AT but tried to keep 100% backwards compatibility?

This is an in-browser ARM PC emulator, running an ARM port of MS-DOS 4 with full accurate PC hardware (VGA graphics, Sound Blaster, IDE, etc) and a ton of software ported to a very DOS-like ABI running ARM instructions. Off-the shelf games and applications like Doom, Quake, the GEM desktop and more were ported and recompiled for ARM-DOS.

Clones of many DOS applications were created, like a full Turbo C style IDE (with TinyCC as a compiler) or a pretty extensive QuickBasic like IDE are there.

You can launch TERM (a ProComm like terminal emulator) and dial a BBS, that runs as an entire second ARM-DOS PC in your browser and upload/download things and play door games. There's a second early AOL-like dialup service that lets you access real Wikipedia and Hacker News over the authentic speed modem - and even view images full screen and watch the re-encoded GIFs slowly download.

There's also a full Rosetta-like JIT converter. You can take most stock X86 DOS applications and just run them.

This is part an exploration of 80's PC nostalgia, and part a tech demo of what an IBM ARM PC could have been. Then trying to see how over the top this idea could be taken within the confines of a browser.

Nice. Next step is obvious: ship the actual hardware :3

I would be happy to buy!
