It did cover the basic technique used to display the images, but I didn't feel like typing all that in, so I thought I'd leave it to someone else :-). The flyer also men- tioned that all the loops were unrolled, so you had straight line code mainly consisting of LDA... PHA... pairs. It does sort of make you grit your teeth, eh? But the results are well worth it. Rich <jordan%lvva.span@sds.sdsc.edu> BIX: richjordan (Rarely there) GEnie: BARRACUDA
