Good progress. A quick thought on the keyboard. If you're keeping the OS around locations &EC and &ED is zero page contain the keys currently being pressed - obviously that's only two keys but might be enough given the logic you've described above. Reading these values is very quick and might save time/space on your keyboard routine. See page 142 (Osbyte 120) in the advanced user guide for an explanation of their content.
