Blitting images is not done on a line by line basis - if it were, the blit might be a little cleaner, but would be one hell of a lot slower, as the overhead involved in setting up the blitter for each line transfer would be immense. Making CHIP RAM out of 60ns chips and doubling the blitter's transfer rate would help a lot more... at a price. -- Mike Farren farren@well.sf.ca.usa
