Quite.  But I am given to understand that the fact remains that the
mono/color-detection function is still very useful in programming,
because if one uses direct writes to video memory, one needs to know
where it starts.  And that differs between the mono/color screen
types, which are hardware, not software related.  (B000 Hex and B800
Hex actually).  Right?
