Hi

if you look at the code after, you can see that the btst is in fact 
waiting for a byte to be received from the ikbd ; which means a key was 
pressed (or mouse was moved).
then just after, it compares the content of fffc02 with #$01, which is 
the scancode for the 'esc' key.

So, demo is not stuck ; press 'esc' and it will continue. In fact it 
exits. I don't know it's supposed to run sthg instead of exiting, 
someone would need to test on a real falcon. (or look at the source code 
with the demo)
