Lines: 11 Regarding making sure your polling routine gets called at least every 8 msecs: this is the whole problem...once your 80-col card ROM gets into its scroll routine, it's hard to get control again. Easier than interrupts is relocating the whole ROM code to RAM and sticking calls to your polling routine in all the right places.
