Design change: Do keyboard polling internally without calling the kernal in the system bank. For one this performs better (several %), second it allows to handle the function keys in conformance with other platforms. Without the custom keyboard routine, we would have to apply some more magic to the function keys to make them work as with other cc65 targets. git-svn-id: svn://svn.cc65.org/cc65/trunk@2811 b7a2c559-68d2-44c3-8de9-860c34a00d81 2003-12-21 18:43:25 +00:00			`; Ullrich von Bassewitz, 06.08.1998`
