Instead of memcpy'ing the entire screen every time we press enter at the bottom, use the VGA start address register to make a "view" onto the underlying memory that moves downward as we scroll. Eventually we run out of memory and have to reset to the start of the buffer. That's when we memcpy everything. It would be cool if there was some way to get the hardware to act like a ring buffer with automatic wrapping here but I don't know how to do that. |
