The most extraordinary thing here is not only it’s being done, but it’s being done in a proprietary way.

The surface of the AmigaOS is tiny in comparison with any modern system. It’s surprising nobody took a free RTOS and built an Amiga API on top of it, enough to fool Amiga software into being compiled for modern hardware and run directly on real Amigas.

You might have an unduly notion of the amount of "being done". The most "modern" up to date AmigaOS will take several seconds every time you open a drawer (directory) loading icons one by one, even on the fastest possible Amiga (Vampire or emulated one) using modern SSD. Its all dressing a pig for the hardcore fanbase using their Amigas to run SysInfo once a year after buying another $xxx accelerator card and reminiscing about the good old times when they were 14y old kid.

I think that's AROS[1].

When trying to remember its name I also found Apollo OS[2].

Edit: Looks, like Apollo OS is a fork of AROS that is optimized to run on the original Amiga hardware.

ApolloOS is optimized to run on "680x0" hardware, including the FPGA based Vampire accelerators (and presumably the standalone Amiga replacement). So while it will run on original Amiga hardware, it also has optimisations that are Vampire specific (extra instructions etc.)

I see, thanks for the explanation.
