Has anyone given thought to a modern keyboard, and modern character set needs, with CP/M? I think the situation might be close to hopeless; the documentation states explicitly "strip off the 8th bit" eg. 0x7f, so 1968 ASCII it is, but having app subvert the BIOS is common.
Just thought I'd ask before I set the task aside. I'm using a USB keyboard and mapping scan codes straight up; I've done real keyboards with dead keys etc but not for a long time. And honestly don't relish coding it (though I could maybe do it not in the Z80).
But even 512 bytes for a keymap is pushing it. That's 1/128th of total RAM space.
