My only issue with hex is when you have to convert 500 numbers to it, it takes so friggin long

I feel more enlightened about L6 now, though. However, question: does changing a byte in L6 automatically update the LCD or will you need to update the graph buffer? Also I assume updating the screen from L6 is considerably faster than pt-on/pxl-on, right?

Well, I think there may be some confusion here.  The screen is 95x63 pixels in size.  That is a total of 5985 pixels.  The graph buffer is not 5989 bytes long.  It is 748 bytes long.  This works because it is monochrome (black and white).  A pixel is only ever on, or off.  Because of that, you can use binary.  There are 8 bits to a single byte, so if you wanted a dotted line, you could write 01010101b to the graph buffer.
Why this matters is that you can't just write a 1 to the graph buffer and expect a single pixel to change.  From what I know of Axe, it would be very hard indeed to manually change each pixel.
