Very cool!

It (almost) runs on copy.sh V86 emulator: https://copy.sh/v86/

I see the boot process with dots (like linux) and after I have the following message with a red background (if that can help):

    ExDOS64 version 0.01 built 26.03.2016
    =====================================
    Boot error: CPU is not 64-bit capable...

The last lines of the Javascript console:
