Okay, how about a Linus OS? (Debian?)

My input character routine currently goes through the ROM calls, so this
would work.

Having this option would be nice, but not necessary for me at this point. I
do have a keyboard driver I'd eventually like to use. It uses
interrupt-driven sampling instead of busy-wait. But that's way down the
road for me, and maybe not at all. Lots of things to do between then and
now, including earning a living.

Maybe I can help with some of this.

Indeed.

I'm looking for this information, too.
