But "takes longer" is not a measure of drawing speed. The space, measured in pixels, is missing in this equation : (drawing speed) = (pixels drawn) / (time to draw them).
There is another factor to the equation - the memory architecture of the frame buffer. The A2 video memory map is, from a software point of view, quite simply ghastly! The calculations to find a video pixel memory address are orders of magnitude greater than simply shifting an address or even being able to simply increment an address when crossing a byte boundary.
Any 'enhanced' video mode would most likely have a much, much nicer addressing scheme for the frame buffer.
And that will make a difference - particularly in BASIC. Regards, -- | Mark McDougall | "Electrical Engineers do it | <http://members.iinet.net.au/~msmcdoug> | with less resistance!"
