I don't recall the processor. I was using it on period H/W, and in at least one case it was an IBM PS/2 with an 8514 graphics adapter and writing to it using some graphics primitives. The only wonk thing I recall was that if I cranked up the compiler optimizations, it just drew lines at various angles all over the screen instead of the images I needed. IIRC there were a few cranky things about writing directly to the graphics but I don't recall problems otherwise.
