Hi again..
    Ok, I dug up SetDepth from the tech notes.. and prototyped the function:

pascal short SetDepth(GDHandle gdh, short newDepth, short whichFlags, 
                            short newFlags)
                = {0x203C, 0x000A, 0x0013, 0xAAA2};

then call:
    SetDepth(gdh, 1, 1, 0) 

to change to monochrome 1 bit.

and voila!  It worked!  BUT.. sigh... when I change myscreen from 8 bit
to 1 bit, my mouse goes looney, and when I change back, it's looney
too...  (when I change from 8 bit color to 8 bit monochrome, no
worries).  Any ideas
