Why not implement direct screen output in UZIX, or rather, in the C-library,
so that all programs can use standard C functions and still benefit from
very high speed screen writes? Interslotcalls for every character you write
still slow down your programs considerably. If you've seen how great direct
screen writes work in CP/M 3.0 for the MSX (yes, another OS), you'll never
even consider using BIOS calls again.
