I've been following this project for a while and I must say it is pretty impressive.

It's actually quite easy to build the most basic version without peripherals. You can just hook it up to your serial port and interact with it like that. Of course it's text-only.

I am working on the i/o system. The current i/o is unbuffered and very slow. I want to create an optimized routine for handling input and output buffers.

After that I will work some more on the commandline interface. I want it to be more versatile. Something you would actually want to work with. Basic features like command history would be nice. I am barely using any ram at the moment, so I have quite a bit to work with. OS ram usage should be under 1K though, so user applications have enough headroom.


Edit: git updated. Some minor tweaks as well as added comments.
