If you dumb the memory at $FC00 and _plotSScreen (which he probably uses)
and write a program that combines the two based on this info

Both pixels set - BLACK
Pixel set at $FC00 - Dark grey
Pixel set at _plotSScreen - Light Grey
No pixel Set - White

and create a bitmap based on this.
Not too hard, I guess. Of course I'm a little rusty with C. But the
.PCX format is pretty simple to do this
