I have spent considerable effort into improving 'rainbow.c' and 'vtvideo.c' now. A bezel with nice LEDs is there and RAM up to 896 K is recognized by the native BIOS.

Still, error messages 13 and 50 are beyond my grasp.
Is there hope for a working keyboard any time soon?

I am willing to debug, too smile

Apart from the keyboard, what steps will have to be taken next? Is it the floppy or the not-yet-existing hard disc?
Guess the non-standard layouts could cause problems.

P.S.: i know nothing about slot devices, so i went to implement addon hardware via DIP switches. Hope no one bothers.
