The known examples of German BBC MOS return X=&FF.
Action: Scan for a range of keys
X=1..127 lowest internal key number to start at EOR &7F
Y=255
On exit X=internal key number pressed (or 255 for none)
Action: Scan for a particular key
X=128..255 internal key number to scan for EOR &80
Y=255
On exit X=Y=0 for as not pressed
X=Y=255 the key was being pressed
