thanx for the quick reply. that's all i wanted to know. after the above
code didn't work, the first thing i tried was copying that memory range
into main memory, and then fwriting. just wanted to check if it was something
we screwed up in designing the co-processor card.

a further question: does that mean that with any of these
hi-res displays that are available (ie: 1024 by 1024 type monochrome
display, etc) you cannot save out the screen memory directly to hard
disk?? does that mean that you are forced to always copy the screen
image into main memory, and then save it out?? 

a further further question: does anyone out there actually own one
of these hi-res mono displays???? if so, how do you like it??
