I am in desparate need of help from those who have used the NEC 7220 Graphics
Display Controller on an 8*86/88.

I am having difficulty in drawing circles in complement mode that EXACTLY use
all the pixels. I have cases where the arcs that make the circle over-draw
their end point and erase the effect of the complemented pixels at the 45
degree points (45, 135, 225, and 315).

Help!! Please send me any examples that you have.

Thanx!

Peter Barada
